# ocracy.backends

Implemented OCR backends.

Each real backend is a subpackage with a `config.py` (`BACKEND_CONFIG`) and an
`adapter.py` (`Adapter` with a `read` method). The registry
([`ocracy.registry`](ocracy.registry.html.md#module-ocracy.registry)) discovers them automatically. Subpackages whose name
starts with `_` (e.g. `ocracy.backends._template`) are scaffolding
helpers, not real backends, and are skipped by discovery.

To add a backend, scaffold one from the template:

```default
from ocracy.make_backend import scaffold_backend
scaffold_backend("easyocr")   # creates ocracy/backends/easyocr/ from the template
```
