 ## Installation
-In a terminal call this command:
-`go get github.com/jesseduffield/lazygit`
-(if you don't have Go installed, you can follow the installation guide [here](https://golang.org/doc/install).
 
-Then just call `lazygit` in your terminal inside a git repository.
-
-If you want, you can also add an alias for this with `echo "alias lg='lazygit'" >> ~/.zshrc` (or whichever rc file you're using).
-
-Please note:
-If you get an error claiming that lazygit cannot be found or is not defined, you may need to add `~/go/bin` to your $PATH (MacOS/Linux), or `%HOME%\go\bin` (Windows)
+### Homebrew
+```sh

+### Void Linux

+
+### Arch Linux
+Packages for Arch Linux are available via AUR (Arch User Repository).
+
+There are two packages. The stable one which is built with the latest release

+also add an alias for this with `echo "alias lg='lazygit'" >> ~/.zshrc` (or

 ## Work in progress
-This is still a work in progress so there's still bugs to iron out and as this is my first project in Go the code could no doubt use an increase in quality, but I'll be improving on it whenever I find the time. If you have any feedback feel free to [raise an issue](https://github.com/jesseduffield/lazygit/issues)/[submit a PR](https://github.com/jesseduffield/lazygit/pulls).
