+CI Debug Notes
+================
+To validate some circleci stuff, I was able to run a “build locally” using the steps below.
+The local build runs in a docker container.
+
+  * (Once) Install circleci client (`brew install circleci`)
+
+  * Convert the “real” config.yml into a self contained (non-workspace) config via:
+
+        circleci config process .circleci/config.yml > .circleci/local-config.yml
+
+  * Run a local build with the following command:
+
+        circleci local execute -c .circleci/local-config.yml --job 'github-maven-deploy/build-and-test'
+
+    With the above command, those operations what cannot occur locally will show an error (like `Error: FAILED with error not supported`), but the build will proceed and can complete “successfully”, which allows you to verify scripts in your config, etc.
