+# If you install the codacy-analysis-cli tool (which depends on Docker) you
+# can run codacy locally and get reports
+#
+# This runs those reports and puts them in a common directory
+#
+# Typical usage scenario is to checkout master, run it with
+# `codacy-ankidroid.sh master`
+#
+# ...then check your branch out and run:
+# `codacy-ankidroid.sh <branchname>
+#
+# Finally, run a diff between the two reports and clean things up before a push
