+###Running Tests
+
+The plugin uses the Mocha, Sinon, Chai stack for testing. Included in the repo is a `Makefile` setting up both testing and code coverage. To run tests,  simply type `make test` into the console while in the root directory of the plugin. Code coverage is similar, simply run `make coverage` to generate an lcov report. Be sure you have lcov installed first. More information on lcov can be found [here](http://ltp.sourceforge.net/coverage/lcov.php). You can cleanup the report folders by running the `make clean` command.
