+## CONTRIBUTING TO PI4J
+
+### Adding a feature or solving a problem
+
+If you have and idea to extend and improve Pi4J, please first create a ticket to discuss how 
+it fits in the project and how it can be implemented. 
+
+If you find a bug, create a ticket, so we are aware of it and others with the same problem can 
+contribute what they already investigated. And the quickest way to get a fix? Try to search for 
+the cause of the problem or even better provide a code fix!
+
+### Code styling
+
+To prevent unnecessary code (tabs versus spaces, number of characters per line...) we have 
+defined an [editorconfig](.editorconfig) for IntelliJ IDEA. You can find [more info 
+here](https://www.jetbrains.com/help/idea/configuring-code-style.html) about its use.
+
+Some tips to keep the code clean and readable:
+* Short methods with a clear name
+* Use SonarLint to get improvement tips while code
+* Use shortcuts
+    * CTRL+ALT+L: Reformat code
+    * CTRL+ALT+O: Optimize imports
+
+### Join the team
+
+You want to become a member of the Pi4J-team? Great idea! Send a short message to [email protected] 
+with your experience, ideas, and what you would like to contribute to the project.

+**TEXT BELOW TO BE MOVED TO NEW WEBSITE**
+
+  Earlier versions of Pi4J
   were perhaps too ambitious in scope and that led to significant project
   bloat to the point that the project was becoming unsustainable.  The goal
   moving forward is to limit scope to that of the raw I/O capabilities
