 ## Running locally
 
 To run it locally
 
 1. Clone this repo.
 2. Install the [App Engine SDK for Go](https://cloud.google.com/appengine/docs/go/download).
-4. Make sure your `$GOPATH` is set to something reasonable, like `$HOME/go`.
-5. Run `dev_appserver.py .` in the checked out directory.
-6. Run `curl -XPOST http://localhost:8080/_configure -d '{"FCMConf": {"ServerKey": SERVER_KEY_FROM_FCM}, "OAuth": {"ClientID": CLIENT_ID_FROM_GOOGLE_CLOUD_PROJECT, "Secret": SECRET_FROM_GOOGLE_CLOUD_PROJECT}, "SendGrid": {"APIKey": SEND_GRID_API_KEY}}'`.

    - This isn't necessary to run the server per se, but `FCMConf` is necessary for FCM message sending, `OAuth` is necessary for non `fake-id` login, and `SendGrid` is necessary for email sending.
 
 ### Faking user ID
@@ -57,8 +66,6 @@ To run the tests
 
 1. Start the local server with a `--clear_datastore` to avoid pre-test clutter and `--datastore_consistency_policy=consistent` to avoid eventual consistency. Since the tests don't wait around for consistency to be achieved, this simplifies writing the tests. Also, use `--require_indexes` so that you verify all the necessary indices are present in `app/index.yaml`. If you find indices for `Game` missing, update and run `go run tools/genindex.go`, for other entity types remove `app/index.yaml`, run `go run tools/genindex.go` and then run the tests without `--require_indexes` to let `dev_appserver.py` add missing indices as it comes across them. The reason `Game` indices are special is that they are built using composite indexes according to https://cloud.google.com/appengine/articles/indexselection.
