+	Description: `Manage the access control list for the ntfy server.
+
+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

 Please also refer to the [rate limiting](#rate-limiting) settings below, specifically `visitor-attachment-total-size-limit`
 and `visitor-attachment-daily-bandwidth-limit`. Setting these conservatively is necessary to avoid abuse.
 
+## 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

+- 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"
+    ```
+    ntfy publish \
+        -u phil:mypass \
+        ntfy.example.com/mysecrets \
+        "Look ma, with auth"
+    ```
+
+=== "HTTP"

+    Host: ntfy.example.com

+        }
+    })
+    ```
+
+=== "Go"
+    ``` go
+    req, _ := http.NewRequest("POST", "https://ntfy.example.com/mysecrets",
+        strings.NewReader("Look ma, with auth"))
+    req.Header.Set("Authorization", "Basic cGhpbDpteXBhc3M=")
+    http.DefaultClient.Do(req)
+    ```
+
+=== "Python"
+    ``` python
+    requests.post("https://ntfy.example.com/mysecrets",
+        data="Look ma, with auth",
+        headers={
+            "Authorization": "Basic cGhpbDpteXBhc3M="
+        })
+    ```
+
+=== "PHP"
+    ``` php-inline
+    file_get_contents('https://ntfy.example.com/mysecrets', false, stream_context_create([
+        'http' => [

   only e-mails to `ntfy-$topic@ntfy.sh` will be accepted. If this is not set, all emails to `$topic@ntfy.sh` will be

 ## 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.

+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`)
-> since 2021-12-17
+> Deprecated 2021-12-17, behavior changed with v1.10.0
 
 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

+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 server-amd64            - Build server/client binary (amd64, no web app or docs)
+  make install-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 amd64), 
+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 server-...` targets:
+
+``` shell
+$ make
+Build server & client (not release version):
+  make server                  - Build server & client (all architectures)
+  make server-amd64            - Build server & client (amd64 only)
+  make server-armv7            - Build server & client (armv7 only)
+  make server-arm64            - Build server & client (arm64 only)
+```
+
+So if you're on an amd64/x86_64-based machine, you may just want to run `make server-amd64` during testing. On a modern
+system, this shouldn't take longer than 5-10 seconds. I often combine it with `install-amd64` so I can run the binary
+right away:
+
+``` shell
+$ make server-amd64 install-amd64
+$ ntfy serve
+```
+
+**During development of the main app, you can also just use `go run main.go`**, as long as you run 
+`make server-deps-static-sites`at least once and `CGO_ENABLED=1`:
+
+``` shell
+$ export CGO_ENABLED=1
+$ make server-deps-static-sites
+$ go run main.go serve
+2022/03/18 08:43:55 Listening on :2586[http]
+...
+```
+
+If you don't run `server-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 `server-deps-static-sites`
+target creates dummy files that ensures that you'll be able to build.
+
+
+### 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 server` (or `make server-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
 * **F-Droid:** The `fdroid` flavor does not include Firebase or Google dependencies

+* [play/](https://github.com/binwiederhier/ntfy-android/tree/main/app/src/play) - Google Play / Firebase specific code
+* [fdroid/](https://github.com/binwiederhier/ntfy-android/tree/main/app/src/fdroid) - F-Droid Firebase stubs
+* [build.gradle](https://github.com/binwiederhier/ntfy-android/blob/main/app/build.gradle) - Main build file
+
+### IDE/Environment
+You should download [Android Studio](https://developer.android.com/studio) (or [IntelliJ IDEA](https://www.jetbrains.com/idea/) 
+with the relevant Android plugins). Everything else will just be a pain for you. Do yourself a favor. 😀

+Depending on whether the server is configured to support [access control](../config.md#access-control), some topics
+may be read/write protected so that only users with the correct credentials can subscribe or publish to them.
+To publish/subscribe to protected topics, you can use [Basic Auth](https://en.wikipedia.org/wiki/Basic_access_authentication)
