+This repo contains my Neovim config only.
+You still need Neovim and a few system tools installed.
 
-## Quick start
+## Fastest setup
 
 ```bash
 git clone https://git.sailorpunisher.com/sailor/nvim-config.git ~/nvim-config
-sh ~/nvim-config/install.sh
+sh ~/nvim-config/bootstrap.sh
 nvim
 ```
 
-If `~/.config/nvim` already exists, `install.sh` will back it up and replace it.
-If it is already this repo, it will just update it with `git pull --ff-only`.
+`bootstrap.sh` installs the dependencies for your distro, then installs the config.
