+## Versioning
+
+The recipe model uses a crude versioning scheme:_
+- The baseUri and filename of the recipe schema is `recipe-vX.json`
+- `X` is be the number of the version of the recipe format the model represents, starting at `1`.
+    - When a breaking change is made, the number shall be incremented by one. The old version should also be kept, with the previous version number, and in a separate file and model. 
+    - This number may be used to select which version of the standard to process in [blue-build/cli](https://github.com/blue-build/cli/)
