It should be accessible it at http://127.0.0.1:5000/

You can change the code and it'll be live instantly. You don't need to start it again.

SQLite is used for database. All the contect is inside database.db.

SQLAlchemy: https://docs.sqlalchemy.org/en/13/orm/tutorial.html

If you change the attributes of an already existing table, you should delete database.db and we should start over. It'll be created on it's own and you don't have to create it again, but we'll lose all the existing data. We should start using Alembic (https://alembic.sqlalchemy.org/en/latest/index.html) to migrate properly.

git checkout -b your-branch
