# Branching streams (merge)

Branching is a method of maintaining the relationship between sets of related files. Branches can evolve separately from their ancestors and descendants, and you can propagate (merge) changes from one branch to another as desired.

To create a stream, use the `p4 merge` command. The `p4 merge` command is also used to propagate changes between existing sets of files. For details about merging changes, see Merge changes.
