 ## Contributing
-We use [commitizen](https://github.com/commitizen/cz-cli), so run `npm run cm` to make commits. A command-line form will appear, requiring you answer a few questions to automatically produce a nicely formatted commit. Releases, semantic version numbers, tags and changelogs will automatically be generated based on these commits thanks to [semantic-release](https://github.com/semantic-release/semantic-release). Be good.

+## Tests
+
+Reviewing a package's tests are a great way to get familiar with it. It's direct insight into the capabilities of the given package (if the tests are thorough). What's even better is a screenshot of the tests neatly organized and grouped (you know the whole "a picture says a thousand words" thing). 
+
+Below is a screenshot of this module's tests running in [Wallaby](https://wallabyjs.com) *("An Integrated Continuous Testing Tool for JavaScript")* which everyone in the React community should be using. It's fantastic and has taken my entire workflow to the next level. It re-runs your tests on every change along with comprehensive logging, bi-directional linking to your IDE, in-line code coverage indicators, **and even snapshot comparisons + updates for Jest!** I requestsed that feature by the way :). It's basically a substitute for live-coding that inspires you to test along your journey.
