 ## WSL (Arch)
 
+Tout d'abord, installer [ArchWSL](https://github.com/yuk7/ArchWSL/releases)
+(.appx et [.cer](https://wsldl-pg.github.io/ArchW-docs/Install-Certificate/))
+
+Ensuite, il faut définir un utilisateur :
+
+```bash
+>Arch.exe
+[root@PC-NAME]# echo "%wheel ALL=(ALL) ALL" > /etc/sudoers.d/wheel
+[root@PC-NAME]# useradd -m -G wheel -s /bin/bash anri
+[root@PC-NAME]# passwd anri
+[root@PC-NAME]# exit
+
+>Arch.exe config --default-user anri
+```
+
 Commande pour lancer mon installation :
 
 ```bash
-curl https://git.mylloon.fr/Anri/confOS/raw/branch/main/arch_wsl.sh -s | sudo bash
+curl https://git.mylloon.fr/Anri/confOS/raw/branch/main/arch_wsl.sh -s | bash
