 ## Installation
 
+### Site web
+Rendez-vous sur le [site d'Upsilon](https://getupsilon.web.app/) à la section "Installer".
+Si votre calculatrice est reconnue, qu'elle contient une version d'Epsilon inférieure à 16 et que votre navigateur accepte WebUSB, la page vous proposera d'installer Upsilon.  
+Ne débranchez votre calculatrice qu'une fois l'installation terminée.

+<summary>Avec WSL 2</summary>
+
+WSL est un système qui virtualise un environnement GNU/Linux dans Windows.
+
+Votre version de windows doit être >= 1903.
+
+#### Installation de WSL
+
+1. Apuyez simulatanément sur les touches "windows" et "x" puis cliquez sur "Powershell administrateur". Entrez ensuite ceci dans la nouvelle fenêtre:
+```powershell
+dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux all /norestart
+```
+Cette commande active WSL
+
+```powershell
+dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart
+```
+Cette commande permet d'autoriser le démarrage des machines signées par Microsoft.
+
+2. Redémarrez votre ordinateur.
+
+3. Téléchargez ce fichier [this file](https://wslstorestorage.blob.core.windows.net/wslblob/wsl_update_x64.msi) et suivez les instructions d'installation.
+
+4. Ouvrez votre fenêtre powershell comme avant et tapez:
+```powershell
+wsl --set-default-version 2
+```
+5. téléchargez [Ubuntu](https://www.microsoft.com/store/apps/9n6svws3rx71) depuis le Microsoft store. Vous pouvez aussi installer [Debian](https://www.microsoft.com/store/productI9MSVKQC78PK6).
+
+WSL est maintenant installé.
+
+### Installation d'usbipd pour connecter la calculatrice à WSL (facultatif)
+Pour connecter la calculatrice, il faut installer cet [outil](https://github.com/dorssel/usbipd-win/releases/download/v1.3.0/usbipd-win_1.3.0.msi). Il permet de connecter deperiphériques USpar internet.Suivez les instructions pour installer.
+
+#### Ubuntu
+1. Dans un terminal WSL Ubuntu, tapez:
+```bash
+sudo apt install linux-tools-5.4.0-77-generic hwdata
+```
+2. Editez /etc/sudoers pour que l'on puisse utiliser la commande usbip. Sur Ubutu, cele est fait de cette manière:
+```bash
+sudo visudo
+```
+3. Ajoutez `/usr/lib/linux-tools/5.4.0-77-generic` au début du secure_path. Après édition, la ligne devrait ressembler à:
+`Defaults secure_path="/usr/lib/linux-tools/5.4.0-77-generic:/usr/local/sbin:..."`
+
+#### Debian
+1.Si vous utiliser Debian, utilisez cette commande:
+```bash
+sudo apt install usbip hwdata usbutils
+```
+
+### Pour connecter la calculatrice à WSL
+1. Ouvrez encore un powershell en mode administrateur et tapez:
+```powershell
+  usbipd wsl list
+```
+Ceci va lister les périphériques USB connectés à l'ordinateur. Reagrdez le BUSID de votre "Numworks Calculator".
+
+2. Maintenant, lancez cette commande en remplçant <BUSID> par celui de votre caculatrice:
+```powershell
+usbipd wsl attach --busid <BUSID>
+```
+
+Le mot de passe de votre machine WSL vous sera demandé.
+
+Vous pouvez aller à l'étape 2.

+
+### 2. Récupérer le code source
+
+
+Le code source est disponible dans une repository git. Récupérez-le de cette manière:
 
 ```bash
 git clone --recursive https://github.com/Lauryy06/Upsilon.git
 cd Upsilon
-git checkout omega-master
+git checkout upsilon-dev
+```

+
+<summary>With WSL 2</summary>
+
+You need a windows version >= 1903.
+
+#### WSL Installation
+
+1. Use simultaneously win + X keys and then click on "admin powershell".
+```powershell
+dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux all /norestart
+```
+This command activate WSL functionalities.
+
+```powershell
+dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart
+```
+This one allows virtual machines developed by Microsoft.
+
+2. Restart your computer.
+
+3. Download [this file](https://wslstorestorage.blob.core.windows.net/wslblob/wsl_update_x64.msi) and follow instructions.
+
+4. Now open powershell admin like before and type:
+```powershell
+wsl --set-default-version 2
+        ```
+5. Download [Ubuntu](https://www.microsoft.com/store/apps/9n6svws3rx71) from Microsoft store.
+
+WSL is now installed.
+
+### Usbipd installation to connect your calculator
+If you want to connect to the calculator, you have to connect to install this [tool](https://github.com/dorssel/usbipd-win/releases/download/v1.3.0/usbipd-win_1.3.0.msi). This will allow you toconnect WSL to the calculator through internet. Follow the on screen information to install.
+#### Ubuntu
+1. In a WSL Ubuntu command prompt, type:
+```bash
+sudo apt install linux-tools-5.4.0-77-generic hwdata
+```
+2. Edit /etc/sudoers so that root can find the usbip command. On Ubuntu, run this command.
+```bash
+sudo visudo
+```
+3. Add `/usr/lib/linux-tools/5.4.0-77-generic` to the beginning of secure_path. After editing, the line should look similar to this.
+`Defaults secure_path="/usr/lib/linux-tools/5.4.0-77-generic:/usr/local/sbin:..."`
+
+#### Debian
+
+1. If you use debian for your WSL distro, use this command instead:
+```bash
+sudo apt install usbip hwdata usbutils
+```
+And that's all for installation and set up.
+
+### To connect your calculator
+1. Open an Admin powershell and type:
+```powershell
+  usbipd wsl list
+```
+This will list your usb devices connected. Look at the BUSID column and remember the one for your calculator (it should be called "Numworks Calculator").
+2. Now run this command replacing <BUSID> by your calculator's usb port id:
+```powershell
+usbipd wsl attach --busid <BUSID>
+```
+It will ask you to type your wsl's password and will connect your calculator to WSL.
+
+You can now go to step 2!
