+# Cute Seal Fanpage
+
+> An experiment using [Nix](https://nixos.org/), [Hakyll](https://jaspervdj.be/hakyll/), [Haskell](https://www.haskell.org/), and [shell scripts](https://en.wikipedia.org/wiki/Bourne_shell) to automate a simple website deployment pipeline.
+
+## Why Seals?
+
+It's an in-joke.
+
+## What's all this code?
+
+seal-blog/
+
+- devops/
+  - build.sh
+    - Uses a [nix-shell](https://nixos.wiki/wiki/Development_environment_with_nix-shell) expression to build the Hakyll executable
+
+  - configuration.nix
+    - The [configuration file for the NixOS](https://nixos.org/manual/nixos/stable/index.html#ch-configuration) production server. This takes care of installing all the necessary software, setup [Nginx](https://www.nginx.com/), and get [ACME certs](https://en.wikipedia.org/wiki/Automated_Certificate_Management_Environment) for verification.
+
+  - newSealPost.sh
+    - Script to be called daily by a cron job on the server. Generates the post for the day, builds and commits.
+
+- website/
+  - A basic Hakyll site, slightly modified to serve seals. Most of the site is generated from the `site.hs` file. Check the [Hakyll](https://jaspervdj.be/hakyll/) documentation for more info.
+
+## Work to be done
+
+- The blog post generation and the hosting of the website are currently intertwined when they should be separated
+  - Seal post generator just makes posts
+  - Hakyll blog imports or calls the post generator
+  - The deployed server/nix config file has a cron job for adding a new blog and committing every day
+- Need to move the blog and post generation inside nixos-apps on my beefier server
+  - The configuration file here is for it's own Linode, the current small one running, but I have a better setup for that now
+  - Pull out the useful parts for my deployed server, remove anything not necessary for a small config file
+  - Also switch to using caddy if not already
+- Experiment with `*` A records
+  - For the seal blog
+  - Instead of having `www` and `git` and `...` subdomains spelled out in Namecheap
+  - Just have a `*` record and have caddy do the filtering
