+Our `Haskell Stack` build uses `Nix` in order to install the non-Haskell dependencies needed by the project.
+If you don't have `Nix` installed, then you may need to install `gmp` and `zlib` development libraries for the build to succeed.

 This will then start up the server on port 8080. The devcontainer process will then automatically expose this port so that you can connect to it from any terminal (it doesn't have to be a terminal running in the devcontainer).
