## 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
* sqlalchemy
The required versions are pinned in the pyproject.toml file.
## Optional dependencies
*ormar* has three optional dependencies based on database backend you use:
### Database backend
#### Postgresql
```py
pip install ormar[postgresql]
```
Will install also `asyncpg` and `psycopg2`.
#### Mysql
```py
pip install ormar[mysql]
```
Will install also `aiomysql` and `pymysql`.
#### Sqlite
```py
pip install ormar[sqlite]
```
Will install also `aiosqlite`.
### Orjson
```py
pip install ormar[orjson]
```
Will install also `orjson` that is much faster than builtin json parser.
### Crypto
```py
pip install ormar[crypto]
```
Will install also `cryptography` that is required to work with encrypted columns.
### Manual installation of dependencies
Of course, you can also install these requirements manually with `pip install asyncpg` etc.
