The base install uses a local JSON file for storage (stdlib only). For shared
|

dev→server storage, install the mongo extra:
|
||||
|
||||
```bash
|

pip install "envelope_authorizer[mongo] @ git+ssh://git@git.rethinkstudios.io/rethink-public/envelope_authorizer.git@v0.1.2"

|
||||
```
|
||||
|
||||
Installing pulls `envelope_crypto` (and `mongo` with the extra). After install,
|
||||
the `authorizer` command is on your PATH; `python -m envelope_authorizer` also works.
