        The `orm` package is an async ORM for Python, with support for Postgres,
        MySQL, and SQLite. ORM is built with:
        
        * [SQLAlchemy core][sqlalchemy-core] for query building.
        * [`databases`][databases] for cross-database async support.
        * [`typesystem`][typesystem] for data validation.
        
        Because ORM is built on SQLAlchemy core, you can use Alembic to provide
        database migrations.
        
        **ORM is still under development: We recommend pinning any dependencies with `orm~=0.1`**
        
        ---
        
        ## Installation
        
        ```shell
        $ pip install orm
        ```
        
        You can install the required database drivers with:
        
        ```shell
        $ pip install orm[postgresql]
        $ pip install orm[mysql]
        $ pip install orm[sqlite]
        ```
        
        Driver support is provided using one of [asyncpg][asyncpg], [aiomysql][aiomysql], or [aiosqlite][aiosqlite].
        Note that if you are using any synchronous SQLAlchemy functions such as `engine.create_all()` or [alembic][alembic] migrations then you still have to install a synchronous DB driver: [psycopg2][psycopg2] for PostgreSQL and [pymysql][pymysql] for MySQL.

        ## Quickstart
        
        **Note**: Use `ipython` to try this from the console, since it supports `await`.
        
        ```python
        import databases
        import orm
        import sqlalchemy
        
        database = databases.Database("sqlite:///db.sqlite")
        metadata = sqlalchemy.MetaData()
        
        
        class Note(orm.Model):
            __tablename__ = "notes"
            __database__ = database
            __metadata__ = metadata
            id = orm.Integer(primary_key=True)
            text = orm.String(max_length=100)
            completed = orm.Boolean(default=False)
        
        # Create the database and tables
        engine = sqlalchemy.create_engine(str(database.url))
        metadata.create_all(engine)
        
        await Note.objects.create(text="Buy the groceries.", completed=False)
        
        note = await Note.objects.get(id=1)
        print(note)
        # Note(id=1, text="Buy the groceries.", completed=False)
        ```
