+This patches folder is managed by quilt, which is a tool for automatic patch
+application and removal. To use quilt with the patches in this directory,
+navigate to the top level directory of this repository, and do:
+
+ $ quilt setup patches/series
+
+To add an externally created patch (in other words, one created with ```diff
+--git``` or ```git diff```), place that .patch or .diff file in this directory,
+and do:
+
+ $ quilt import patches/<patchfile>
+
+Then, to apply the new patch, do:
+
+ $ quilt push
+
+Removing patches from the stack can be done with:
+
+ $ quilt pop
+
+Please see the man quilt(1) for more information on adding and importing new
+patches. The debian package maintainer guides also have chapters on quilt
+usage.
