How to set up and validate locally

Important

This requires Geo setup on your GDK which you can do using the easy installation method. Setup is straightforward but takes some time. Alternatively, you may simply validate the code functionally.

If needed, I can upload more screen recordings if there's a specific scenario that you would like to validate. Or we could set up a call so I can share my instance with you.

1. Enable the geo_primary_verification_view feature flag.
2. Go to your primary Geo page (usually localhost:3000).
3. Go to /admin/data_management?model_name=snippet_repository
4. Click the checksum all button.
