+How to Run a Bulk Send Simulation
+==================================
+
+Assuming that you have followed all steps to set up localstack successfully, do the following:
+
+1. Create an sms template that requires no inputs from the user (i.e. the csv file will only have phone numbers)
+2. Uncomment the test 'test_generate_csv_for_bulk_testing' in app/test_utils.py
+3. Run `make test` on this project.  This will generate the csv file for the bulk test.
+4. If you are not a platform admin for your service when you run locally, do the following:
+   - >psql -d notification_api
+   - update users set platform_admin='t';
+   - \q
+   - sign out
+   - sign in.
+   - Go to settings and set the organization for your service to 'Broadcast services' (scroll down to platform admin)
+   - Go to settings and set your service to 'live' (scroll down to platform admin)
+5. Run your app 'locally'.  I.e. run `make run-procfile` on this project and `make run-flask` on the admin project
+6. Sign in.  Verify you are running with localstack.  I.e., you do NOT receive a text message on sign in.  Instead, 
+   you see your authentication code in green in the api logs
+7. Go to send messages and upload your csv file and send your 100000 messages
