+# hakyll-nix-template
+
+[Hakyll](https://jaspervdj.be/hakyll/) + [Nix](https://nixos.org) template
+
+## Quick tips
+
+* Read the tutorial to get started! https://robertwpearce.com/the-hakyll-nix-template-tutorial.html
+* If you make changes to anything inside of `ssg/`, you'll need to clean the
+  hakyll cache and rebuild. This is the preferred series of commands for
+  rebuilding (with logs), cleaning the cache, and re-running the dev server:
+  
+  ```default
+  nix build --print-build-logs && \
+    nix run . clean && \
+    nix run . watch
+  ```
+
+## Features
+
+* Build your site into the `./result/dist` folder:
+  ```
+  λ nix build
+  ```
+* Start hakyll's dev server that reloads when changes are made:
+  ```
+  λ nix run . watch
+  Listening on http://127.0.0.1:8000
+  ...more logs
+  ```
+* Run any hakyll command through `nix run .`!
+  ```
+  λ nix run . clean
+  Removing dist...
+  Removing ssg/_cache...
+  Removing ssg/_tmp...
+  ```
+* Start a development environment that
+  * has your shell environment
+  * has `hakyll-site` (for building/watching/cleaning hakyll projects)
+  * has `hakyll-init` (for generating new projects)
+  * can have anything else you put in the `shell.buildInputs` of the
+    `hakyllProject` in `flake.nix`
+  * is set up to run `ghci` with some defaults and the modules loaded so you can
+    make your own changes and test them out in the ghci REPL
+
+  ```
+  λ nix develop
+
+  [hakyll-nix]λ hakyll-site build
+  ...
+  Success
+
+  [hakyll-nix]λ ghci
+  ...
+  [1 of 1] Compiling Main    ( ssg/src/Main.hs, interpreted )
+  ...
+
+  λ >
+  ```
+
+### hakyll
+
+All of this is custmomizable, and here are some things that are already done for
+you:
+
+* [pandoc](https://github.com/jgm/pandoc/) markdown customization to make it as
+  close to GitHub's markdown style as possible
+* [`slugger`](https://hackage.haskell.org/package/slugger) module is included that makes nice link URIs based on post titles
+* RSS & Atom XML feed generation
+* Sitemap generation
+* Code syntax highlighting customization
+* ...other reasonable defaults
+
+Configure the dev server, cache & tmp directories, and more in
+`./ssg/src/Main.hs`.
+
+### Deployment
+
+Deployment is set up through a [GitHub
+Action](https://github.com/features/actions) with [cachix](https://cachix.org),
+and it deploys to a [GitHub Pages](https://pages.github.com/) branch,
+`gh-pages`, when you merge code into your main branch.
+
+Setup information can be found below in the "Cachix" section.
+
+Note: If your main branch's name isn't `main`, ensure `'refs/heads/main'` gets
+updated to `'refs/heads/my-main-branch'` in `./github/workflows/main.yml`.
+
+## Setup
+
+### Nix & Flakes
+
+If you don't have [nix](https://nixos.org), follow [the nix installation
+instructions](https://nixos.org/download.html).
+
+Once you have nix installed, follow the instructions here to get access to
+flakes: https://nixos.wiki/wiki/Flakes.
+
+### Cachix
+
+The `./.github/workflows/main.yml` file builds with help from
+[cachix](https://app.cachix.org), so you'll need to generate a signing key to be
+able to do this.
+
+1. Create a cache on cachix for your project
+1. Follow cachix's instructions to generate a signing keypair
+1. Copy the signing keypair value to a new `CACHIX_SIGNING_KEY` secret on
+   https://github.com/settings/secrets
