 ## 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).
 
-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)
+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)
 
 ### Ubuntu
