## Configuring

This project usese environment variables to work. For most cases, the
defaults work but some sensitive info like keys must be overridden. Copy
the file in `config/env.dist` to `.env` in the project root and override
the values.

When running with `make run`, it'll pick up these values automatically.
If you're doing it the hard way, you'll have to source them.
