minor changes to setup flow

Summary:
1. The setup flow complains if you haven't updated your schema, so that section
should be moved above the setup flow.

2. The setup flow tells you to lower your timeout, but it doesn't tell you how
low will make it stop complaining.

Test Plan:
Didn't test the setup.
Regenerated the docs and saw the change.
