 ## What's all this code?
 
-- [config.dhall](./config.dhall)
-  - Typed non-deterministic config file for modifying the generator.
-- [flake.nix](./flake.nix)
-  - Entry point for all the nix ways of running and building the code.
-- [generateSealPosts.hs](./generateSealPosts.hs)
-  - A Haskell script that creates a blog post for every day from the configured date until the current day.

+  - generateSealPosts.hs
+    - A Haskell script that checks the website/posts folder and creates a blog post for every day from 1998 until the current date. There you will find the adjective lists if you think of more words to describe seals.
+- dist/
+  - Place for the Haskell build artifacts to go.
 
 ## These seals need more adjectives
 
-In [config.dhall](./config.dhall) you'll find two lists of adjectives. For the repo and add your own! Editing dhall config files does not require recompilation of the Haskell executable!

+- Should running the generate function replace existing posts, or not? Probably not.
