If you're here, you might be looking to contribute. Here's some very helpful commands for devs:
npm run db:migrate # Run all the migrations up to the latest one.
npm run db:seed # Run all the seed scripts. Run this after migrating.
npm run db:reset # Drop all the tables and start over.
# You almost always want to run db:migrate after this.
npm run db:sql # Connect to the postgresql docker server to run raw SQL
