WIP: User Manual: Merge new user manual for issue #2298 Composition Guidelines

User manual: Merge new user manual for issue #2298 (closed) Composition Guidelines

Currently, there is no documentation explaining how to use composition guidelines.

The problem is that users cannot access the user manual to see how to enable composition guidelines.

The fix was to add a description and image visualization for the composition guidelines

This doesn't close issue #2298 (closed) but provides documentation for the MR that closes it
