ATLAS Offline software ======================== General Topics -------------- Please see the [master branch readme](https://gitlab.cern.ch/atlas/athena/blob/master/README.md) for general information and links. This Branch ----------- This branch is `21.0-mc16a` which contains the code for the ATLAS MC16a campaign. This branch supports builds of the `Athena` project, as numbered releases `21.0.20.Y` because the branch was made to ensure consistency with the AtlasOffline 21.0.20 build, which was the starting point for the MC16a campaign.
