This directory contains Jiri manifests that list the source code and prebuilt dependencies of Fuchsia that get downloaded by jiri update.
Many of these manifests are updating automatically by “rollers” - scheduled jobs that create and submit CLs.
If making a change manually, you can test the impact of the change locally by running jiri update -local-manifest-project=fuchsia, and then using fx build and the rest of your normal Fuchsia development workflow to test the change.
If making a change to a <package> entry in a manifest, you'll need to run manifests/update-lockfiles.sh to resolve the pinned versions to immutable content addresses to ensure determinism.
