## Installation

Installation is as simple as:

```py
pip install ormar
```

### Dependencies

Ormar uses `databases` for connectivity issues, `pydantic` for validation and `sqlalchemy-core` for queries.

All three should install along the installation of ormar if not present at your system before.

*  databases
*  pydantic>=1.5 
*  sqlalchemy 


## Optional dependencies

pip install ormar[postgresql]
```
Will install also `asyncpg` and `psycopg2`.

### Mysql

```

```

### Orjson
