 If you have specific needs for your workflow or want to create fun projects, the extension port provides the flexibility to build and experiment.
 
 We encourage the community to build custom add-ons for JetKVM.
-If you create a hardware extension that works with the RJ-11 extension port, you'll be able to **submit a pull request** to the JetKVM project once the source code becomes available in early December when the first devices ship. We enthusiastically welcome contributions from the community and look forward to collaborating on new features that benefit all JetKVM users.

 ## Build your own extensions
 
-The extension port is designed to unlock endless opportunities for hardware modifications. Using a standard RJ-11 connector, it provides power, I2C, and GPIO pins that make it easy to develop your own custom extensions.
