 [Hakyll](https://jaspervdj.be/hakyll/) + [Nix](https://nixos.org/) template
 
+## Usage
+
+1. Click the "Use this template" button and create your repository
+1. Renaming
+  1. Rename all instances of `hakyll-nix-template` and `my-site` with a name for
+     your project
+  1. Rename `generator/my-site.cabal` to reflect your project name
+1. Cachix
+  1. Create a cachix cache for your project on https://app.cachix.org
+  1. Follow the cachix instructions to generate a signing keypair
+  1. Copy the signing keypair value to a new `CACHIX_SIGNING_KEY` secret on
+     https://github.com/<MYUSER>/<MY-PROJECT>/settings/secrets
+1. Run `nix-build` to build the project and `nix-shell` to open the nix shell
+1. If you want to update `niv` and the other pinned dependencies, then in the
+   `nix-shell` run `niv init` and then `niv update` and then `exit` to leave the
+   nix shell
+1. To start an environment for running hakyll commands like `hakyll-site watch`
+   (the dev server) and `hakyll-site build`: `cd generator && nix-shell`. You'll
+   then have access to the `hakyll-site` executable defined in
+   `generator/my-site.cabal`. While you can do `nix-shell` in the root and then
+   `cd generator && hakyll-site watch`, you get some more tools if you
+   `nix-shell` from within the `generator/` folder.
+1. Once you're satisfied, create a branch, push your project up there, and check
+   that the GitHub Actions successfully build. If so, you're good to merge your
+   project with your main branch.
+1. Once you have a successful build on your main branch, open
+   https://github.com/<MYUSER>/<MY-PROJECT>/settings and set the GitHub Pages
+   branch to be the `gh-pages` branch
+
 ## Features
+
 tl;dr: `nix-build` will collect all your pinned dependencies, build your hakyll
 site, and output the built site in a `result/` directory. If you set up the
 [main GitHub Action](./.github/workflows/main.yml) with what it needs (your
