 # How to contribute
 
-Todo
+## TL;DR
+
+The project is massive - if you like it do consider to contribute!
+
+## Getting started
+
+Currently I'm keeping a private dashboard to prioritize new features and bug fixes.
+
+If you want to propose something please open a new issue or to reach me using 
+my email address [valerioageno@yahoo.it](mailto:valerioageno@yahoo.it). 
+I'm also available on twitter (X) DMs @valerioageno, [linkedin][https://www.linkedin.com/in/valerioageno) 
+and discord @__v__v__.
+
+## Requirements 
+To contribute to tuono is not strictly required to know both typescript and rust (even though it
+would be a great nice to have). Most of the feature tasks can be handled solely on
+the client or the server side.
