Clarify Settings migrated to projects generated from Templates
Problem to solve
Related to #461846
When creating a project from a template, it's not clear which settings are copied.
Our documentation states the following is copied:
- Branches
- Commits
- Tags
But then also in the same section says:
To learn more about what is migrated, see Items that are exported.
Which adds many examples:
Project configuration
Merge requests
Merge request approvers
Push rules
etc...
In practice we can see some settings are copied over, but fail to work correctly as shown in #461846 for merge request rules when using a group of approvers.

Proposal
Clarify exactly what can be copied from a template, and what cannot
