how to build?

[geofflangenderfer]

I'd like to contribute, but I can't build.

What I've tried:

• bash build.sh
• cabal build run-server [1]

Could we add build instruction to readme or CONTRIBUTING.md?

[1]:

✦ ❯ cabal build run-server
Build profile: -w ghc-8.10.7 -O1
In order, the following will be built (use -v for more details):
 - run-server-1.0.0 (exe:run-server) (first run)
Preprocessing executable 'run-server' for run-server-1.0.0..
Building executable 'run-server' for run-server-1.0.0..
