-### Linux
+Please check the official doc on how to install Neovim on different systems: https://github.com/neovim/neovim/blob/master/INSTALL.md
 
-You can directly download the binary release from [here](https://github.com/neovim/neovim/releases/download/stable/nvim-linux64.tar.gz).
+After installing Nvim, we need to set the PATH to nvim correctly.
-You can also use the system package manager to install nvim,
-but that is not reliable since the latest version may not be available.
-
-### Windows
-
-You may download from [nvim release](https://github.com/neovim/neovim/releases/download/stable/nvim-win64.zip) from GitHub and manually extract it.
-
-Another way to install Nvim on Windows is via chocolatey or scoop:
-
-```
-choco install neovim
-
-# via scoop
-# scoop bucket add versions
-# scoop install neovim
-```
-
-### macOS
-
-It is recommended to install neovim via [Homebrew](https://brew.sh/) on macOS. Simply run the following command:
-
-```bash
-brew install neovim
-```
-
-After installing Nvim, we need to set the path to nvim correctly.
 **Make sure that you can run `nvim` from the command line after all these setups**.
 
 ## Setting up Nvim
 
 After installing nvim and all the dependencies, we will install plugin managers and set up this config.
