+## Updating Neovim
+
+Doom-nvim currently requires neovim `^v0.7.x`, check your neovim version by running `nvim -v` in the command line.
+
+## MacOS / Brew
+
+1. Ensure you have [https://brew.sh/](https://brew.sh/) installed.
+2. Run `brew install neovim` to install the latest version.
+
+## Ubuntu / apt-get
+
+Ubuntu doesn't always have the latest neovim in its own internal PPA.  You will have to add the neovim ppa to get the latest versions.
+
+1. Ensue you have software-properties-common (allows you to add extra ppa sources): `sudo apt install software-properties-common -y`.
+2. Import the stable nim ppa. `sudo add-apt-repository ppa:neovim-ppa/stable -y`.
+3. Run update to sync changes `sudo apt-get update`.
+4. Install the latest stable neovim: `sudo apt install neovim -y`
