+
+A version controlled recipe for Oat Milk Chai.
+
+## Background
+I was struggling to find a good chai recipe that used oat milk instead of regular milk, so I started experimenting with my own recipe. Hope you like it!
+
+## Suggesting an improvement
+Please raise a PR for any improvements that you suggest
+
+## Backward compatibility
+This repository supports backward compatibility on the satisfaction of a good chai. However, YMMV, and I recommend using the `main` branch for the best experience.
