 **ntfy** (pronounce: *notify*) is a simple HTTP-based [pub-sub](https://en.wikipedia.org/wiki/Publish%E2%80%93subscribe_pattern) notification service.
 It allows you to **send notifications to your phone or desktop via scripts** from any computer, entirely **without signup or cost**.
 It's also open source (as you can plainly see) if you want to run your own.

+
+This is a server-only command. It directly manages the user.db as defined in the server config
+file server.yml. The command only works if 'auth-file' is properly defined. Please also refer
+to the related command 'ntfy user'.
+
+The command allows you to show the access control list, as well as change it, depending on how
+it is called.
+
+Usage:
+  ntfy access                            # Shows access control list (alias: 'ntfy user list')
+  ntfy access USERNAME                   # Shows access control entries for USERNAME
+  ntfy access USERNAME TOPIC PERMISSION  # Allow/deny access for USERNAME to TOPIC
+
+Arguments:
+  USERNAME     an existing user, as created with 'ntfy user add', or "everyone"/"*"
+               to define access rules for anonymous/unauthenticated clients
+  TOPIC        name of a topic with optional wildcards, e.g. "mytopic*"
+  PERMISSION   one of the following:
+               - read-write (alias: rw) 
+               - read-only (aliases: read, ro)
+               - write-only (aliases: write, wo)
+               - deny (alias: none)
+
+Examples:
+  ntfy access                        # Shows access control list (alias: 'ntfy user list')
+  ntfy access phil                   # Shows access for user phil
+  ntfy access phil mytopic rw        # Allow read-write access to mytopic for user phil
+  ntfy access everyone mytopic rw    # Allow anonymous read-write access to mytopic
+  ntfy access everyone "up*" write   # Allow anonymous write-only access to topics "up..." 
+  ntfy access --reset                # Reset entire access control list
+  ntfy access --reset phil           # Reset all access for user phil
+  ntfy access --reset phil mytopic   # Reset access for user phil and topic mytopic

-see [server.yml](https://github.com/binwiederhier/ntfy/blob/main/config/server.yml)), via command line arguments

+!!! info
+    Definitely check out the **[server.yml](https://github.com/binwiederhier/ntfy/blob/main/server/server.yml)** file.

+
+The most basic settings are `base-url` (the external URL of the ntfy server), the HTTP/HTTPS listen address (`listen-http`
+and `listen-https`), and socket path (`listen-unix`). All the other things are additional features.

+## Access control
+By default, the ntfy server is open for everyone, meaning **everyone can read and write to any topic** (this is how
+ntfy.sh is configured). To restrict access to your own server, you can optionally configure authentication and authorization. 
+
+ntfy's auth is implemented with a simple [SQLite](https://www.sqlite.org/)-based backend. It implements two roles 
+(`user` and `admin`) and per-topic `read` and `write` permissions using an [access control list (ACL)](https://en.wikipedia.org/wiki/Access-control_list). 
+Access control entries can be applied to users as well as the special everyone user (`*`), which represents anonymous API access. 
+
+To set up auth, simply **configure the following two options**:
+
+* `auth-file` is the user/access database; it is created automatically if it doesn't already exist; suggested 
+  location `/var/lib/ntfy/user.db` (easiest if deb/rpm package is used)
+* `auth-default-access` defines the default/fallback access if no access control entry is found; it can be
+  set to `read-write` (default), `read-only`, `write-only` or `deny-all`.
+
+Once configured, you can use the `ntfy user` command to [add or modify users](#users-and-roles), and the `ntfy access` command
+lets you [modify the access control list](#access-control-list-acl) for specific users and topic patterns. Both of these 
+commands **directly edit the auth database** (as defined in `auth-file`), so they only work on the server, and only if the user 
+accessing them has the right permissions.
+
+### Users and roles
+The `ntfy user` command allows you to add/remove/change users in the ntfy user database, as well as change
+passwords or roles (`user` or `admin`). In practice, you'll often just create one admin 
+user with `ntfy user add --role=admin ...` and be done with all this (see [example below](#example-private-instance)).
+
+**Roles:**
+
+* Role `user` (default): Users with this role have no special permissions. Manage access using `ntfy access`
+  (see [below](#access-control-list-acl)).
+* Role `admin`: Users with this role can read/write to all topics. Granular access control is not necessary.
+
+**Example commands** (type `ntfy user --help` or `ntfy user COMMAND --help` for more details):
+
+```
+ntfy user list                     # Shows list of users (alias: 'ntfy access')
+ntfy user add phil                 # Add regular user phil  
+ntfy user add --role=admin phil    # Add admin user phil
+ntfy user del phil                 # Delete user phil
+ntfy user change-pass phil         # Change password for user phil
+ntfy user change-role phil admin   # Make user phil an admin
+```
+
+### Access control list (ACL)
+The access control list (ACL) **manages access to topics for non-admin users, and for anonymous access (`everyone`/`*`)**.
+Each entry represents the access permissions for a user to a specific topic or topic pattern. 
+
+The ACL can be displayed or modified with the `ntfy access` command:
+
+```
+ntfy access                            # Shows access control list (alias: 'ntfy user list')
+ntfy access USERNAME                   # Shows access control entries for USERNAME
+ntfy access USERNAME TOPIC PERMISSION  # Allow/deny access for USERNAME to TOPIC
+```
+
+A `USERNAME` is an existing user, as created with `ntfy user add` (see [users and roles](#users-and-roles)), or the 
+anonymous user `everyone` or `*`, which represents clients that access the API without username/password.
+
+A `TOPIC` is either a specific topic name (e.g. `mytopic`, or `phil_alerts`), or a wildcard pattern that matches any
+number of topics (e.g. `alerts_*` or `ben-*`). Only the wildcard character `*` is supported. It stands for zero to any 
+number of characters.
+
+A `PERMISSION` is any of the following supported permissions:
+
+* `read-write` (alias: `rw`): Allows [publishing messages](publish.md) to the given topic, as well as 
+  [subscribing](subscribe/api.md) and reading messages
+* `read-only` (aliases: `read`, `ro`): Allows only subscribing and reading messages, but not publishing to the topic
+* `write-only` (aliases: `write`, `wo`): Allows only publishing to the topic, but not subscribing to it
+* `deny` (alias: `none`): Allows neither publishing nor subscribing to a topic 
+
+**Example commands** (type `ntfy access --help` for more details):
+```
+ntfy access                        # Shows entire access control list
+ntfy access phil                   # Shows access for user phil
+ntfy access phil mytopic rw        # Allow read-write access to mytopic for user phil
+ntfy access everyone mytopic rw    # Allow anonymous read-write access to mytopic
+ntfy access everyone "up*" write   # Allow anonymous write-only access to topics "up..."
+ntfy access --reset                # Reset entire access control list
+ntfy access --reset phil           # Reset all access for user phil
+ntfy access --reset phil mytopic   # Reset access for user phil and topic mytopic
+```
+
+**Example ACL:**
+```
+$ ntfy access
+user phil (admin)
+- read-write access to all topics (admin role)
+user ben (user)
+- read-write access to topic garagedoor
+- read-write access to topic alerts*
+- read-only access to topic furnace
+user * (anonymous)
+- read-only access to topic announcements
+- read-only access to topic server-stats
+- no access to any (other) topics (server config)
+```
+
+In this example, `phil` has the role `admin`, so he has read-write access to all topics (no ACL entries are necessary).
+User `ben` has three topic-specific entries. He can read, but not write to topic `furnace`, and has read-write access
+to topic `garagedoor` and all topics starting with the word `alerts` (wildcards). Clients that are not authenticated
+(called `*`/`everyone`) only have read access to the `announcements` and `server-stats` topics.
+
+### Example: Private instance
+The easiest way to configure a private instance is to set `auth-default-access` to `deny-all` in the `server.yml`:
+
+=== "/etc/ntfy/server.yml"
+    ``` yaml
+    auth-file: "/var/lib/ntfy/user.db"
+    auth-default-access: "deny-all"
+    ```
+
+After that, simply create an `admin` user:
+
+```
+$ ntfy user add --role=admin phil
+password: mypass
+confirm: mypass
+user phil added with role admin 
+```
+
+Once you've done that, you can publish and subscribe using [Basic Auth](https://en.wikipedia.org/wiki/Basic_access_authentication) 
+with the given username/password. Be sure to use HTTPS to avoid eavesdropping and exposing your password. Here's a simple example:
+
+=== "Command line (curl)"
+    ```
+    curl \
+        -u phil:mypass \
+        -d "Look ma, with auth" \
+        https://ntfy.example.com/mysecrets
+    ```

+=== "ntfy CLI"

+    ```
+
+=== "HTTP"

+## iOS instant notifications
+Unlike Android, iOS heavily restricts background processing, which sadly makes it impossible to implement instant 
+push notifications without a central server. 
+
+To still support instant notifications on iOS through your self-hosted ntfy server, you have to forward so called `poll_request` 
+messages to the main ntfy.sh server (or any upstream server that's APNS/Firebase connected, if you build your own iOS app),
+which will then forward it to Firebase/APNS.
+
+To configure it, simply set `upstream-base-url` like so:
+
+``` yaml
+upstream-base-url: "https://ntfy.sh"
+```
+
+If set, all incoming messages will publish a poll request to the configured upstream server, containing
+the message ID of the original message, instructing the iOS app to poll this server for the actual message contents.
+
+If `upstream-base-url` is not set, notifications will still eventually get to your device, but delivery can take hours,
+depending on the state of the phone. If you are using your phone, it shouldn't take more than 20-30 minutes though.
+
+In case you're curious, here's an example of the entire flow: 
+
+- In the iOS app, you subscribe to `https://ntfy.example.com/mytopic`
+- The app subscribes to the Firebase topic `6de73be8dfb7d69e...` (the SHA256 of the topic URL)
+- When you publish a message to `https://ntfy.example.com/mytopic`, your ntfy server will publish a 
+  poll request to `https://ntfy.sh/6de73be8dfb7d69e...`. The request from your server to the upstream server 
+  contains only the message ID (in the `X-Poll-ID` header), and the SHA256 checksum of the topic URL (as upstream topic).
+- The ntfy.sh server publishes the poll request message to Firebase, which forwards it to APNS, which forwards it to your iOS device
+- Your iOS device receives the poll request, and fetches the actual message from your server, and then displays it
+
+Here's an example of what the self-hosted server forwards to the upstream server. The request is equivalent to this curl:
+
+```
+curl -X POST -H "X-Poll-ID: s4PdJozxM8na" https://ntfy.sh/6de73be8dfb7d69e32fb2c00c23fe7adbd8b5504406e3068c273aa24cef4055b

+### Firebase limits
+If [Firebase is configured](#firebase-fcm), all messages are also published to a Firebase topic (unless `Firebase: no` 
+is set). Firebase enforces [its own limits](https://firebase.google.com/docs/cloud-messaging/concept-options#topics_throttling)
+on how many messages can be published. Unfortunately these limits are a little vague and can change depending on the time 
+of day. In practice, I have only ever observed `429 Quota exceeded` responses from Firebase if **too many messages are published to 
+the same topic**. 
+
+In ntfy, if Firebase responds with a 429 after publishing to a topic, the visitor (= IP address) who published the message
+is **banned from publishing to Firebase for 10 minutes** (not configurable). Because publishing to Firebase happens asynchronously,
+there is no indication of the user that this has happened. Non-Firebase subscribers (WebSocket or HTTP stream) are not affected.
+After the 10 minutes are up, messages forwarding to Firebase is resumed for this visitor.
+
+If this ever happens, there will be a log message that looks something like this:
+```
+WARN Firebase quota exceeded (likely for topic), temporarily denying Firebase access to visitor
+```

 ## Tuning for scale
 If you're running ntfy for your home server, you probably don't need to worry about scale at all. In its default config,
 if it's not behind a proxy, the ntfy server can keep about **as many connections as the open file limit allows**.

+## Debugging/tracing
+If something's not working right, you can debug/trace through what the ntfy server is doing by setting the `log-level`
+to `DEBUG` or `TRACE`. The `DEBUG` setting will output information about each published message, but not the message 
+contents. The `TRACE` setting will also print the message contents. 
+
+!!! warning
+    Both options are very verbose and should only be enabled in production for short periods of time. Otherwise, 
+    you're going to run out of disk space pretty quickly.
+
+You can also hot-reload the `log-level` by sending the `SIGHUP` signal to the process after editing the `server.yml` file.
+You can do so by calling `systemctl reload ntfy` (if ntfy is running inside systemd), or by calling `kill -HUP $(pidof ntfy)`. 
+If successful, you'll see something like this:
+
+```
+$ ntfy serve
+2022/06/02 10:29:28 INFO Listening on :2586[http] :1025[smtp], log level is INFO

 ## Config options
 Each config option can be set in the config file `/etc/ntfy/server.yml` (e.g. `listen-http: :80`) or as a
 CLI option (e.g. `--listen-http :80`. Here's a list of all available options. Alternatively, you can set an environment
 variable before running the `ntfy` command (e.g. `export NTFY_LISTEN_HTTP=:80`).

+    All config options can also be defined in the `server.yml` file using underscores instead of dashes, e.g. 
+    `cache_duration` and `cache-duration` are both supported. This is to support stricter YAML parsers that do 
+    not support dashes.

 ## Active deprecations
 
+### Android app: WebSockets will become the default connection protocol  
+> Active since 2022-03-13, behavior will change in **June 2022**
+
+In future versions of the Android app, instant delivery connections and connections to self-hosted servers will
+be using the WebSockets protocol. This potentially requires [configuration changes in your proxy](https://ntfy.sh/docs/config/#nginxapache2caddy).
+
+Due to [reports of varying battery consumption](https://github.com/binwiederhier/ntfy/issues/190) (which entirely 
+seems to depend on the phone), JSON HTTP stream support will not be removed. Instead, I'll just flip the default to 
+WebSocket in June.
+
+### Android app: Using `since=<timestamp>` instead of `since=<id>`
+> Active since 2022-02-27, behavior will change in **May 2022**
+
+In about 3 months, the Android app will start using `since=<id>` instead of `since=<timestamp>`, which means that it will
+not work with servers older than v1.16.0 anymore. This is to simplify handling of deduplication in the Android app.
+
+The `since=<timestamp>` endpoint will continue to work. This is merely a notice that the Android app behavior will change.

 ### Running server via `ntfy` (instead of `ntfy serve`)

 As more commands are added to the `ntfy` CLI tool, using just `ntfy` to run the server is not practical
 anymore. Please use `ntfy serve` instead. This also applies to Docker images, as they can also execute more than

-# Building

+Hurray 🥳 🎉, you are interested in writing code for ntfy! **That's awesome.** 😎
+
+I tried my very best to write up detailed instructions, but if at any point in time you run into issues, don't 
+hesitate to **contact me on [Discord](https://discord.gg/cT7ECsZj9w) or [Matrix](https://matrix.to/#/#ntfy:matrix.org)**.
 
 ## ntfy server
-The ntfy server source code is available [on GitHub](https://github.com/binwiederhier/ntfy). 
-To quickly build on amd64, you can use `make build-simple`:
+The ntfy server source code is available [on GitHub](https://github.com/binwiederhier/ntfy). The codebase for the
+server consists of three components:
 
-```
-git clone git@github.com:binwiederhier/ntfy.git
-cd ntfy
-make build-simple
+* **The main server/client** is written in [Go](https://go.dev/) (so you'll need Go). Its main entrypoint is at 
+  [main.go](https://github.com/binwiederhier/ntfy/blob/main/main.go), and the meat you're likely interested in is 
+  in [server.go](https://github.com/binwiederhier/ntfy/blob/main/server/server.go). Notably, the server uses a 
+  [SQLite](https://sqlite.org) library called [go-sqlite3](https://github.com/mattn/go-sqlite3), which requires 
+  [Cgo](https://go.dev/blog/cgo) and `CGO_ENABLED=1` to be set. Otherwise things will not work (see below).
+* **The documentation** is generated by [MkDocs](https://www.mkdocs.org/) and [Material for MkDocs](https://squidfunk.github.io/mkdocs-material/),
+  which is written in [Python](https://www.python.org/). You'll need Python and MkDocs (via `pip`) only if you want to
+  build the docs.
+* **The web app** is written in [React](https://reactjs.org/), using [MUI](https://mui.com/). It uses [Create React App](https://create-react-app.dev/)
+  to build the production build. If you want to modify the web app, you need [nodejs](https://nodejs.org/en/) (for `npm`) 
+  and install all the 100,000 dependencies (*sigh*).
+
+All of these components are built and then **baked into one binary**. 
+
+### Navigating the code
+Code:
+
+* [main.go](https://github.com/binwiederhier/ntfy/blob/main/main.go) - Main entrypoint into the CLI, for both server and client
+* [cmd/](https://github.com/binwiederhier/ntfy/tree/main/cmd) - CLI commands, such as `serve` or `publish`
+* [server/](https://github.com/binwiederhier/ntfy/tree/main/server) - The meat of the server logic
+* [docs/](https://github.com/binwiederhier/ntfy/tree/main/docs) - The [MkDocs](https://www.mkdocs.org/) documentation, also see `mkdocs.yml`
+* [web/](https://github.com/binwiederhier/ntfy/tree/main/web) - The [React](https://reactjs.org/) application, also see `web/package.json`
+
+Build related:
+
+* [Makefile](https://github.com/binwiederhier/ntfy/blob/main/Makefile) - Main entrypoint for all things related to building
+* [.goreleaser.yml](https://github.com/binwiederhier/ntfy/blob/main/.goreleaser.yml) - Describes all build outputs (for [GoReleaser](https://goreleaser.com/))
+* [go.mod](https://github.com/binwiederhier/ntfy/blob/main/go.mod) - Go modules dependency file
+* [mkdocs.yml](https://github.com/binwiederhier/ntfy/blob/main/mkdocs.yml) - Config file for the docs (for [MkDocs](https://www.mkdocs.org/))
+* [web/package.json](https://github.com/binwiederhier/ntfy/blob/main/web/package.json) - Build and dependency file for web app (for npm)
+
+
+The `web/` and `docs/` folder are the sources for web app and documentation. During the build process,
+the generated output is copied to `server/site` (web app and landing page) and `server/docs` (documentation).
+
+### Build requirements
+
+* [Go](https://go.dev/) (required for main server)
+* [gcc](https://gcc.gnu.org/) (required main server, for SQLite cgo-based bindings)
+* [Make](https://www.gnu.org/software/make/) (required for convenience)
+* [libsqlite3/libsqlite3-dev](https://www.sqlite.org/) (required for main server, for SQLite cgo-based bindings)
+* [GoReleaser](https://goreleaser.com/) (required for a proper main server build)
+* [Python](https://www.python.org/) (for `pip`, only to build the docs) 
+* [nodejs](https://nodejs.org/en/) (for `npm`, only to build the web app)
+
+### Install dependencies
+These steps **assume Ubuntu**. Steps may vary on different Linux distributions.
+
+First, install [Go](https://go.dev/) (see [official instructions](https://go.dev/doc/install)):
+``` shell
+wget https://go.dev/dl/go1.18.linux-amd64.tar.gz
+rm -rf /usr/local/go && tar -C /usr/local -xzf go1.18.linux-amd64.tar.gz
+export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin
+go version   # verifies that it worked
 ```
 
-That'll generate a statically linked binary in `dist/ntfy_linux_amd64/ntfy`.
-
-For all other platforms (including Docker), and for production or other snapshot builds, you should use the amazingly 
-awesome [GoReleaser](https://goreleaser.com/) make targets:
-
-```
-Build:
-  make build                       - Build
-  make build-snapshot              - Build snapshot
-  make build-simple                - Build (using go build, without goreleaser)
-  make clean                       - Clean build folder
-
-Releasing (requires goreleaser):
-  make release                     - Create a release
-  make release-snapshot            - Create a test release
+Install [GoReleaser](https://goreleaser.com/) (see [official instructions](https://goreleaser.com/install/)):
+``` shell
+go install github.com/goreleaser/goreleaser@latest
+goreleaser -v   # verifies that it worked
 ```
 
-There are currently no platform-specific make targets, so they will build for all platforms (which may take a while).
+Install [nodejs](https://nodejs.org/en/) (see [official instructions](https://nodejs.org/en/download/package-manager/)):
+``` shell
+curl -fsSL https://deb.nodesource.com/setup_17.x | sudo -E bash -
+sudo apt-get install -y nodejs
+npm -v   # verifies that it worked
+```
+
+Then install a few other things required:
+``` shell
+sudo apt install \
+    build-essential \
+    libsqlite3-dev \
+    gcc-arm-linux-gnueabi \
+    gcc-aarch64-linux-gnu \
+    python3-pip \
+    upx \
+    git
+```
+
+### Check out code
+Now check out via git from the [GitHub repository](https://github.com/binwiederhier/ntfy):
+
+=== "via HTTPS"
+    ``` shell
+    git clone https://github.com/binwiederhier/ntfy.git
+    cd ntfy
+    ```
+
+=== "via SSH"
+    ``` shell
+    git clone git@github.com:binwiederhier/ntfy.git 
+    cd ntfy
+    ```
+
+### Build all the things
+Now you can finally build everything. There are tons of `make` targets, so maybe just review what's there first 
+by typing `make`:
+
+``` shell
+$ make 
+Typical commands (more see below):
+  make build                   - Build web app, documentation and server/client (sloowwww)
+  make cli-linux-amd64         - Build server/client binary (amd64, no web app or docs)
+  make install-linux-amd64     - Install ntfy binary to /usr/bin/ntfy (amd64)
+  make web                     - Build the web app
+  make docs                    - Build the documentation
+  make check                   - Run all tests, vetting/formatting checks and linters
+...
+```
+
+If you want to build the **ntfy binary including web app and docs for all supported architectures** (amd64, armv7, and arm64), 
+you can simply run `make build`:
+
+``` shell
+$ make build
+...
+# This builds web app, docs, and the ntfy binary (for amd64, armv7 and arm64). 
+# This will be SLOW (5+ minutes on my laptop on the first run). Maybe look at the other make targets?
+```
+
+You'll see all the outputs in the `dist/` folder afterwards:
+
+``` bash
+$ find dist 
+dist
+dist/metadata.json
+dist/ntfy_arm64_linux_arm64
+dist/ntfy_arm64_linux_arm64/ntfy
+dist/ntfy_armv7_linux_arm_7
+dist/ntfy_armv7_linux_arm_7/ntfy
+dist/ntfy_amd64_linux_amd64
+dist/ntfy_amd64_linux_amd64/ntfy
+dist/config.yaml
+dist/artifacts.json
+```
+
+If you also want to build the **Debian/RPM packages and the Docker images for all supported architectures**, you can 
+use the `make release-snapshot` target:
+
+``` shell
+$ make release-snapshot
+...
+# This will be REALLY SLOW (sometimes 5+ minutes on my laptop)
+```
+
+During development, you may want to be more picky and build only certain things. Here are a few examples.
+
+### Build the ntfy binary
+To build only the `ntfy` binary **without the web app or documentation**, use the `make cli-...` targets:
+
+``` shell
+$ make
+Build server & client (using GoReleaser, not release version):
+  make cli                        - Build server & client (all architectures)
+  make cli-linux-amd64            - Build server & client (Linux, amd64 only)
+  make cli-linux-armv6            - Build server & client (Linux, armv6 only)
+  make cli-linux-armv7            - Build server & client (Linux, armv7 only)
+  make cli-linux-arm64            - Build server & client (Linux, arm64 only)
+  make cli-windows-amd64          - Build client (Windows, amd64 only)
+  make cli-darwin-all             - Build client (macOS, arm64+amd64 universal binary)
+```
+
+So if you're on an amd64/x86_64-based machine, you may just want to run `make cli-linux-amd64` during testing. On a modern
+system, this shouldn't take longer than 5-10 seconds. I often combine it with `install-linux-amd64` so I can run the binary
+right away:
+
+``` shell
+$ make cli-linux-amd64 install-linux-amd64
+$ ntfy serve
+```
+
+**During development of the main app, you can also just use `go run main.go`**, as long as you run 
+`make cli-deps-static-sites`at least once and `CGO_ENABLED=1`:
+
+``` shell
+$ export CGO_ENABLED=1
+$ make cli-deps-static-sites
+$ go run main.go serve
+2022/03/18 08:43:55 Listening on :2586[http]
+...
+```
+
+If you don't run `cli-deps-static-sites`, you may see an error *`pattern ...: no matching files found`*:
+```
+$ go run main.go serve
+server/server.go:85:13: pattern docs: no matching files found
+```
+
+This is because we use `go:embed` to embed the documentation and web app, so the Go code expects files to be
+present at `server/docs` and `server/site`. If they are not, you'll see the above error. The `cli-deps-static-sites`
+target creates dummy files that ensure that you'll be able to build.
+
+While not officially supported (or released), you can build and run the server **on macOS** as well. Simply run 
+`make cli-darwin-server` to build a binary, or `go run main.go serve` (see above) to run it.
+
+### Build the web app
+The sources for the web app live in `web/`. As long as you have `npm` installed (see above), building the web app 
+is really simple. Just type `make web` and you're in business:
+
+``` shell
+$ make web
+...
+```
+
+This will build the web app using Create React App and then **copy the production build to the `server/site` folder**, so 
+that when you `make cli` (or `make cli-linux-amd64`, ...), you will have the web app included in the `ntfy` binary.
+
+If you're developing on the web app, it's best to just `cd web` and run `npm start` manually. This will open your browser
+at `http://127.0.0.1:3000` with the web app, and as you edit the source files, they will be recompiled and the browser 
+will automatically refresh:
+
+``` shell
+$ cd web
+$ npm start
+```
+
+### Build the docs
+The sources for the docs live in `docs/`. Similarly to the web app, you can simply run `make docs` to build the 
+documentation. As long as you have `mkdocs` installed (see above), this should work fine:
+
+``` shell
+$ make docs
+...
+```
+
+If you are changing the documentation, you should be running `mkdocs serve` directly. This will build the documentation, 
+serve the files at `http://127.0.0.1:8000/`, and rebuild every time you save the source files: 
+
+```
+$ mkdocs serve
+INFO     -  Building documentation...
+INFO     -  Cleaning site directory
+INFO     -  Documentation built in 5.53 seconds
+INFO     -  [16:28:14] Serving on http://127.0.0.1:8000/
+```
+
+Then you can navigate to http://127.0.0.1:8000/ and whenever you change a markdown file in your text editor it'll automatically update.
 
 ## Android app
 The ntfy Android app source code is available [on GitHub](https://github.com/binwiederhier/ntfy-android).
 The Android app has two flavors:
 
-* **Google Play:** The `play` flavor includes Firebase (FCM) and requires a Firebase account
+* **Google Play:** The `play` flavor includes [Firebase (FCM)](https://firebase.google.com/) and requires a Firebase account

+## Watchtower (shoutrrr)
+You can use [shoutrrr](https://github.com/containrrr/shoutrrr) generic webhook support to send 
+[Watchtower](https://github.com/containrrr/watchtower/) notifications to your ntfy topic.
+
+Example docker-compose.yml:
+```yml
+services:
+  watchtower:
+    image: containrrr/watchtower
+    environment:
+      - WATCHTOWER_NOTIFICATIONS=shoutrrr
+      - WATCHTOWER_NOTIFICATION_URL=generic+https://ntfy.sh/my_watchtower_topic?title=WatchtowerUpdates
+```
+
+Or, if you only want to send notifications using shoutrrr:
+```
+shoutrrr send -u "generic+https://ntfy.sh/my_watchtower_topic?title=WatchtowerUpdates" -m "testMessage"
+```
+
+## Sonarr, Radarr, Lidarr, Readarr, Prowlarr, SABnzbd

+
+## Home Assistant
+Here is an example for the configuration.yml file to setup a REST notify component.
+Since Home Assistant is going to POST JSON, you need to specify the root of your ntfy resource.
+
+```yaml
+notify:
+  - name: ntfy
+    platform: rest
+    method: POST_JSON
+    data:
+      topic: YOUR_NTFY_TOPIC
+    title_param_name: title
+    message_param_name: message
+    resource: https://ntfy.sh
+```
+
+If you need to authenticate to your ntfy resource, define the authentication, username and password as below:
+
+```yaml
+notify:
+  - name: ntfy
+    platform: rest
+    method: POST_JSON
+    authentication: basic
+    username: YOUR_USERNAME
+    password: YOUR_PASSWORD
+    data:
+      topic: YOUR_NTFY_TOPIC
+    title_param_name: title
+    message_param_name: message
+    resource: https://ntfy.sh
+```
+
+If you need to add any other [ntfy specific parameters](https://ntfy.sh/docs/publish/#publish-as-json) such as priority, tags, etc., add them to the `data` array in the example yml. For example:
+
+```yaml
+notify:
+  - name: ntfy
+    platform: rest
+    method: POST_JSON
+    data:
+      topic: YOUR_NTFY_TOPIC
+      priority: 4
+    title_param_name: title
+    message_param_name: message
+    resource: https://ntfy.sh
+```
+
+## Uptime Kuma
+Go to your [Uptime Kuma](https://github.com/louislam/uptime-kuma) Settings > Notifications, click on **Setup Notification**.
+Then set your desired **title** (e.g. "Uptime Kuma"), **ntfy topic**, **Server URL** and **priority (1-5)**:
+
+<div id="uptimekuma-screenshots" class="screenshots">
+    <a href="../static/img/uptimekuma-settings.png"><img src="../static/img/uptimekuma-settings.png"/></a>
+    <a href="../static/img/uptimekuma-setup.png"><img src="../static/img/uptimekuma-setup.png"/></a>
+</div>
+
+You can now test the notifications and apply them to monitors:
+
+<div id="uptimekuma-monitor-screenshots" class="screenshots">
+    <a href="../static/img/uptimekuma-ios-test.jpg"><img src="../static/img/uptimekuma-ios-test.jpg"/></a>
+    <a href="../static/img/uptimekuma-ios-down.jpg"><img src="../static/img/uptimekuma-ios-down.jpg"/></a>
+    <a href="../static/img/uptimekuma-ios-up.jpg"><img src="../static/img/uptimekuma-ios-up.jpg"/></a>
+</div>
+
+## Apprise
+ntfy is integrated natively into [Apprise](https://github.com/caronc/apprise) (also check out the 
+[Apprise/ntfy wiki page](https://github.com/caronc/apprise/wiki/Notify_ntfy)).
+
+You can use it like this:
+
+```
+apprise -vv -t "Test Message Title" -b "Test Message Body" \
+   ntfy://mytopic
+```
+
+Or with your own server like this:
+
+```
+apprise -vv -t "Test Message Title" -b "Test Message Body" \
+   ntfy://ntfy.example.com/mytopic

+
+**Features:**
+
+* Support for auth and user management ([#277](https://github.com/binwiederhier/ntfy/issues/277))

+
+## ntfy server v1.25.2
+Released June 2, 2022
+
+This release adds the ability to set a log level to facilitate easier debugging of live systems. It also solves a 
+production problem with a few over-users that resulted in Firebase quota problems (only applying to the over-users). 
+We now block visitors from using Firebase if they trigger a quota exceeded response.
+
+On top of that, we updated the Firebase SDK and are now building the release in GitHub Actions. We've also got two
+more translations: Chinese/Simplified and Dutch.
+
+**Features:**
+
+* Advanced logging, with different log levels and hot reloading of the log level ([#284](https://github.com/binwiederhier/ntfy/pull/284))
+
+**Bugs**:
+
+* Respect Firebase "quota exceeded" response for topics, block Firebase publishing for user for 10min ([#289](https://github.com/binwiederhier/ntfy/issues/289))
+* Fix documentation header blue header due to mkdocs-material theme update (no ticket)

+## ntfy iOS app v1.1
+Released May 31, 2022
+
+In this release of the iOS app, we add message priorities (mapped to iOS interruption levels), tags and emojis,
+action buttons to open websites or perform HTTP requests (in the notification and the detail view), a custom click
+action when the notification is tapped, and various other fixes.
+
+It also adds support for self-hosted servers (albeit not supporting auth yet). The self-hosted server needs to be
+configured to forward poll requests to upstream ntfy.sh for push notifications to work (see [iOS push notifications](https://ntfy.sh/docs/config/#ios-instant-notifications)
+for details).
+
+**Features:**
+
+* [Message priority](https://ntfy.sh/docs/publish/#message-priority) support (no ticket)

+
+**Bugs:**

+* iOS UI not always updating properly ([#267](https://github.com/binwiederhier/ntfy/issues/267))
+
+## ntfy server v1.24.0
+Released May 28, 2022
+
+This release of the ntfy server brings supporting features for the ntfy iOS app. Most importantly, it
+enables support for self-hosted servers in combination with the iOS app. This is to overcome the restrictive
+Apple development environment.
+
+**Features:**
+
+* Regularly send Firebase keepalive messages to ~poll topic to support self-hosted servers (no ticket)
+* Add subscribe filter to query exact messages by ID (no ticket)
+* Support for `poll_request` messages to support [iOS push notifications](https://ntfy.sh/docs/config/#ios-instant-notifications) for self-hosted servers (no ticket)
+
+**Bugs:**
+
+* Support emails without `Content-Type` ([#265](https://github.com/binwiederhier/ntfy/issues/265), thanks to [@dmbonsall](https://github.com/dmbonsall))
+
+**Additional translations:**
+
+* Italian (thanks to [@Genio2003](https://hosted.weblate.org/user/Genio2003/))
+
+## ntfy iOS app v1.0
+Released May 25, 2022
+
+This is the first version of the ntfy iOS app. It supports only ntfy.sh (no selfhosted servers) and only messages + title
+(no priority, tags, attachments, ...). I'll rapidly add (hopefully) most of the other ntfy features, and then I'll focus
+on self-hosted servers.
+
+The app is now available in the [App Store](https://apps.apple.com/us/app/ntfy/id1625396347).
+
+**Tickets:**
+
+* iOS app ([#4](https://github.com/binwiederhier/ntfy/issues/4), see also: [TestFlight summary](https://github.com/binwiederhier/ntfy/issues/4#issuecomment-1133767150))
+
+**Thanks:**
+
+* Thank you to all the testers who tried out the app. You guys gave me the confidence that it's ready to release (albeit with
+  some known issues which will be addressed in follow-up releases).
+
+## ntfy server v1.23.0
+Released May 21, 2022
+
+This release ships a CLI for Windows and macOS, as well as the ability to disable the web app entirely. On top of that, 
+it adds support for APNs, the iOS messaging service. This is needed for the (soon to be released) iOS app.

+**Features:**
+
+* [Windows](https://ntfy.sh/docs/install/#windows) and [macOS](https://ntfy.sh/docs/install/#macos) builds for the [ntfy CLI](https://ntfy.sh/docs/subscribe/cli/) ([#112](https://github.com/binwiederhier/ntfy/issues/112))

+## ntfy Android app v1.13.0
+Released May 11, 2022
+
+This release brings a slightly altered design for the detail view, featuring a card layout to make notifications more easily
+distinguishable from one another. It also ships per-topic settings that allow overriding minimum priority, auto delete threshold
+and custom icons. Aside from that, we've got tons of bug fixes as usual.
+
+**Features:**
