+# LTS package maintenance utility
+
+This tooling is designed to automate 2 main tasks that are part of
+the package maintenance workflow of Clear Linux LTS. These tasks are:
+- Back-porting of a patch (e.g. security fix) to older branches.
+- Building RPMs with the intent of sharing binaries of older LTS branches to
+  newer branches whenever possible.
+
+There should be no need to run this tool directly. Instead use the following
+targets defined in Makefile.common.lts:
+- lts-show: Show a summary of active LTS branches
+- lts-backport: Attempt to fast-forward the previous active branch to the current branch
+- lts-build: Build RPM in Koji, or reuse existing build from older branch
+
+"Active" branches correspond to LTS releases that currently have support.
+They are listed in a flat file "active-branches" in "lts" directory, from
+oldest to newest. New entries are added by Clear Linux LTS developers as
+new releases become available, and entries removed as releases become
+obsolete.
