+# hs-flake-utils
+
+A nix flake for use with Haskell, for Least Authority.
+
+# How do I make it go?
+
+1. create a directory
+   2. change into that directory
+2. nix-shell -p cabal-install ghc
+   1. cabal init
+   2. answer all the questions to create the project files
+3. copy the project template below into a file named `flake.nix`
+   1. replace the contents of `description` and `packageName` in the newly created `flake.nix`
+4. run `nix develop`
+   Wait for the world to build or the internet to send you cached packages.
