 ## Installation
 
-### Via binary release
-You can download a binary release [here](https://github.com/jesseduffield/lazygit/releases)
-
-### Via Go
-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).
-
-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). Not to be mistaked for `C:\Go\bin` (which is for Go's own binaries, not apps like Lazygit)

 ## 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).
