 # kreeger's dotfiles
 
-My dotfiles. Mostly used for GitHub Codespaces.
+My dotfiles. Also works with the following repos:
+
+- [kreeger/nvimrc](https://git.kree.gr/kreeger/nvimrc)
+- [kreeger/zshrc](https://git.kree.gr/kreeger/zshrc)
+- [kreeger/tmuxrc](https://git.kree.gr/kreeger/tmuxrc)
+
+To use, clone this repo to `$HOME/.config/dotfiles` and run `setup.sh`. This
+makes sure those three repos are cloned to their `$HOME/.config`-equivalent
+homes, that the `zshrc` file is symlinked to my home directory, and that any
+other dotfiles in this repo also get symlinked to home.
+
+My `zshrc` files also include a function (`update_dotfiles`) to do a `git pull`
+on each of these repos to help me keep things up-to-date.
