+## Inclusive Language Statement
+
+These guiding principles are very important to the maintainers and therefore 
+we respectfully ask all contributors to abide by them as well: 
+
+- Consider that users who will read the docs are from different backgrounds and
+cultures and that they have different preferences.
+- Avoid potential offensive terms and, for instance, prefer "allow list and
+deny list" to "white list and black list".
+- We believe that we all have a role to play to improve our world, and even if
+writing inclusive documentation might not look like a huge improvement, it's a
+first step in the right direction.
+- We suggest to refer to
+[Microsoft bias free writing guidelines](https://docs.microsoft.com/en-us/style-guide/bias-free-communication) 
+and 
+[Google inclusive doc writing guide](https://developers.google.com/style/inclusive-documentation) 
+as starting points.
