+This plugin is a simple wrapper around the `appcfg.py` and `gcloud app` commands, which makes it capable of making deployments in the standard environment or flexible environments with any language available.
 
 The `action` configuration variable (shown below) can accept any action that you would normally call on `appcfg.py` or `gcloud app`.
 So far, it has been tested with `update` to deploy and `set_default_version` to migrate traffic in `appcfg` and `gcloud app deploy` for `gcloud app`, but it should also be capable of running helpful ops commands like `update_indexes` and `update_cron`.
