            ## Install

            ### Windows

            1. Extract **nvim-win64.zip** (or **nvim-win32.zip**)
            2. Run `nvim-qt.exe`

            ### macOS

            1. Download **nvim-macos.tar.gz**
            2. Extract: `tar xzvf nvim-macos.tar.gz`
            3. Run `./nvim-osx64/bin/nvim`

            ### Linux (x64)

            1. Download **nvim.appimage**
            2. Run `chmod u+x nvim.appimage && ./nvim.appimage`
               - If your system does not have FUSE you can [extract the appimage](https://github.com/AppImage/AppImageKit/wiki/FUSE#type-2-appimage):
                 ```
                 ./nvim.appimage --appimage-extract
                 ./squashfs-root/usr/bin/nvim
                 ```

            ### Other

            - Install by [package manager](https://github.com/neovim/neovim/wiki/Installing-Neovim)
