+## Note on API stability
+
+While we are on 0.x.y versions, there may be breaking API changes
+between minor (x) versions, while bugfix (y) versions may
+contain fixes, trivial enhancements and development/deployment/documentation tweaks.
+If you are using ResINS it is highly recommended to pin to a specific minor version e.g.
+
+```
+dependencies = [ "resins>=0.1.1,<0.2"]
