If you've read What is Itchy? and feel like you have a good grasp of the technologies we use, you can go ahead and start contributing. Start by forking the itchy-cordova GitHub repository to your own GitHub account. This will let you more easily submit changes via a pull request. Then install Git if you haven't already and clone the repo. Make sure you have all of the correct programs installed:

• Node and NPM
• Cordova's dependencies
• Android Studio (well, technically you just need the SDK but Android Studio is the easiest way to get it)

Now that you've got everything, run npm install to automatically install Cordova and Parcel as well as any other external scripts used in Itchy. Go ahead and run cordova platform add android if you're planning on building an APK file to be run on an Android phone or emulator. Now that you're ready for development, take a look at the project structure.
