 # Automatic CE->EE merge
 
 Commits pushed to CE `master` are automatically merged into EE `master` roughly
-every 5 minutes. Changes are merged using the `ours` merge strategy in the
-context of EE. This means that any merge conflicts are resolved by taking the EE
-changes and discarding the CE changes. This removes the need for resolving
-conflicts or reverting changes, at the cost of **absolutely requiring** EE merge
-requests to be created whenever a CE merge request causes merge conflicts.
-Failing to do so can result in changes not making their way into EE.
