 The goal of this code is to do a soak test of api while we make significant application or infrastructure changes.
 
 There are two soak tests here:
-- `soak_test_send_email.py` will POST an email to api every second.
+- `soak_test_send_notification.py` will POST an email or SMS to api every second.
 - `soak_test_all_servers.py` will do a GET to all our servers (admin, api, dd-api, api-k8s, documentation), on average hitting each server once a second

 Default configuration is in the `locust.conf` file. Note that the `host` is the base address of the system you are testing, for example `https://staging.notification.cdssandbox.xyz` **not** `https://api.staging.notification.cdssandbox.xyz`. The "api" prefix will be added in the code.

-You can supply a `--ref` option to `soak_test_send_email.py` that will set the notification's `client_reference`. This is useful in testing that all POSTs were processed successfully.

@@ -37,7 +39,7 @@ There are two ways to run Locust, with the UI or headless.
 Locally you can run the email soak test with:
 
 ```shell
-locust -f ./soak_test_send_email.py --ref=soak-2023-05-30-A
+locust -f ./soak_test_send_notification.py [--ref=soak-2023-05-30-A] [--sms]
 ```
 
 Follow the localhost address that the console will display to get to the UI. It will ask you how many total users and spawned users you want configured. Once setup, you can manually start the tests via the UI and follow the summary data and charts visually.
