-### Exceptions
-
-Using fast API as example, we may simply throw exception with a proper status code, and an optional error code. We may
-also supply arbitrary key value in args dict, to help frontend render better error message.
-
-```python
-from awesome_sso.exceptions import NotFound
-from fastapi import APIRouter
-
-router = APIRouter()
-
-
-@router.get('/transactions')
-def get(id: str):
-    try:
-        obj = find_by_id(id)
-    except Exception as e:
-        raise NotFound(message='transaction not found' % id, error_code='A0001', args={id: id})
-    ...
-```
-
-And we may implement a common error handler to convert all these errors to proper response schema
-
-```python
-from awesome_sso.exceptions import HTTPException
-from fastapi.requests import Request
-from fastapi.responses import JSONResponse
-
-
-@app.exception_handler(HTTPException)
-async def http_exception_handler(request: Request, exc: HTTPException):
-    return JSONResponse(
-        status_code=exc.status_code,
-        content={
-            'detail': exc.detail,
-            'error_code': exc.error_code,
-        }
-    )
-```
-
-This would result in a response with status code 404, and body
-
-```json
-{
-  "status_code": 404,
-  "detail": {
-    "message": "transaction not found",
-    "id": "some_id"
-  },
-  "error_code": "A0001"
-}
-```
-
-With this response, frontend can decide to simply render detail, or map it to detailed message. If error_code "A0001"
-correspond to the following i18 n entry
-
-```json
-"error.A0001": {"en-US": "transaction can not be found with supplied {id}: {message}"}
-```
-
-we may format message accordingly with
-
-```typescript
-errorMessage = formatMessage({ id: `error.${error.data.error_code}` }, error.data.detail);
-```
-
-Note that error code is not supplied, is default to status code. So it is always safe to simply use error_code in
-frontend to decide what to render.

-### Data Store
-
-#### Minio
-
-refer to `tests/test_minio.py`
-
-#### Mongo
-
-refer to `tests/service/test_user.py`
-
-```python
-from beanie import init_beanie
-from motor.motor_asyncio import AsyncIOMotorClient
-from awesome_sso.service.user.schema import AwesomeUser
-
-
-def init_mongo():
-    settings = YOUR_SETTINGS()
-    models = [AwesomeUser]
-    cli = AsyncIOMotorClient(settings.mongodb_dsn)
-    await init_beanie(
-        database=cli[settings.mongodb_db_name],
-        document_models=models,
-    )
-    for model in models:
-        await model.get_motor_collection().drop()
-        await model.get_motor_collection().drop_indexes()
-```
