 ## Installation
+### Requirements
+Before doing anything, you will need to have `git` installed.<br>
 
-/!\ To be written
+#### Arch
+For Arch Linux users, you can simply execute the `.config/setup.sh` script and get going.
 
+#### Other distributions
+I recommend taking a look at the `.config/setup.sh` script and comment out everything special to Arch (`pacman` and `yay` section).
+Then, I advise to install all packages from source if you run into issues, since everything is meant to be used with latest versions (looking at you `neovim`).
+### Dotfiles installation
+- Clone the repository
+```
+git clone --bare https://github.com/TanguyHerbron/dotfiles.git $HOME/.dotfiles
+```
+- Define a one time alias
+```
+alias dotfiles='/usr/bin/git --git-dir=$HOME/.dotfiles/ --work-tree=$HOME'
+```
+- Checkout the content from the git repository to your `$HOME`
+```
+dotfiles checkout
+```
+
+From this point on, if you have `zsh` installed, the `dotfiles` alias will be added to your shell by default. Otherwise, you might want to add it yourself or instasll `zsh`.

 ## Keybinds
 These are the most used and basic keybinds. You might want to read through `.config/i3/config` to find more keybindings and add your own.
