 # creyPY
 
 My collection of Python and FastAPI shortcuts etc.
+
+## Installation
+
+```bash
+pip install creyPY -U
+```
+
+## Versioning
+
+This library uses [Semantic Versioning](https://semver.org/).
+
+## FastAPI
+
+This library installes fastapi and pydantic, as well as sqlalchemy for you. It also provides a sqlalchemy base class and companion pydantic schemas. Also there are some helper functions for FastAPI in `creyPY.fastapi.app` like `generate_unique_id` to generate unique operation IDs for the OpenAPI schema to work with code generators.
+
+### Database connection
+
+The `creyPY.fastapi.db` module provides a `Session` class that can be used as a context manager to connect to a database. It exposes the `SQLALCHEMY_DATABASE_URL` variable for you to use. It uses the following environment variables:
+
+- `POSTGRES_HOST`: The host of the database
+- `POSTGRES_PORT`: The port of the database
+- `POSTGRES_USER`: The user of the database
+- `POSTGRES_PASSWORD`: The password of the database
+- `POSTGRES_DB`: The database name
+
+Currently only PostgreSQL is supported. It creates a sync session, it is planned to add async support in the future. You can use this like this:
+
+```python
+from creyPY.fastapi.db.session import get_db
+
+async def test_endpoint(
+    db: Session = Depends(get_db),
+) -> Any:
+    pass
+```
+
+## Constants
+
+The constants module contains a few enums that I use in my projects. The best way to understand this library is to look at the code (it's not that much). However for simplicity, here is a brief overview:
+
+- LanguageEnum: Contains all languages according to ISO 639
+- CountryEnum: Contains all countries according to ISO 3166
+- CurrencyEnum: Contains all accepted stripe currencies (Commented out are the Zero-decimal currencies, to avoid custom implementation)
+- StripeStatus: Contains all stripe payment statuses
+- GroupMode: Contains time group modes (e.g. day, week, month, year)
+
+### Usage example
+
+```python
+from creyPY.const import LanguageEnum
+
+print(LanguageEnum.EN) # Output: LanguageEnum.EN
+print(LanguageEnum.EN.value) # Output: English
+```
