+#### autogenerated api frontend
+
+API can autogenerate a frontend that documents, and allows to play
+with, in a limited way, its interface. Make sure you have the
+following variables inside the current `.env`:
+
+```
+docs_url=/docs
+root_path=''
+```
+
+If the `.env` that is in-use is based on `env.default` then it is
+already the case. Start, or restart the http server, then go to
+`https://127.0.0.1:8000/docs`. That is autogenerated documentation
+based on pydantic schema, fastapi routes, and docstrings :wink:.
+
+Happy experiments, and then documentation!
