Installation instructions are pretty vague

I'm having a bit of trouble getting pulldasher to run locally. The instructions in the readme and config.js sort of gloss over some of the setup instructions and required knowledge.

   // The usual MySQL stuff. Like every other MySQL webapp, basically.
   // You will need to source the `schema.sql` file in the database to create
   // all the tables that Pulldasher expects.
   mysql: {
      host: 'mysql remote host URL',
      db:   'database name',
      user: 'username',
      pass: 'password'
   },

Not sure what to put in here. Maybe we could be a little more descriptive in how we connect this to docker?

Trying to help out with some design tweaks here and there but can't get it running 😢

Start with the README and config.js installation guidance, then inspect schema.sql to understand the required database setup. Document the values needed for the MySQL connection and how to connect the application to Docker; done means a newcomer can follow the instructions to run Pulldasher locally.
