Pulp - Story #3209: As a user, I have Repository Versions
Update pulp_file README
The README in pulp_file contains outdated commands.
These need to be updated include but not limited to:
- Creating a importer/publisher doesn't take a repository
- Publishing/syncing requires a repo
- Auto-distributing a distrubtion requires that repo and publisher is set.
- Add/Remove units to a repo
