+  # NEC Decoder
+  
+## Getting started
+
+1. Build your extension by updating the Python files for your needs
+2. Create a public Github repo and push your code 
+3. Update this README
+4. Open the Logic app and publish your extension
+5. Create a Github release
+6. Debug your hardware like you've never done before :)
