# Home API
Google & Co. really do not need to know any healthdata.
So lets start a home api that stores blood pressure, weight
and lets see what follows.
The apis are documented by swagger.
## Configuration
The server is configured by its environment or a .env file
read by python-dotenv:
```
## Where data will be stored
FLASK_SQLALCHEMY_DATABASE_URI=sqlite:///db.sqlite3
## Docker image and registry
DOCKER_IMAGENAME=code.elfring.ms/elfrinjo/homeapi
```
