 Maintaining several versions
 ============================
 
-If you'd like to maintain more than one version of your package, you can use branches on the feedstock. To do this,
-fork your feedstock and make a meaningful branch name (e.g., `v1.X` or `v1.0`).
-Make the required changes to the recipe and rerender the feedstock. Then push this branch
-from your fork to the upstream feedstock. Our CI services will automatically build any
-branches in addition to the default branch.
