All you'll need to get started is edit the properties.mk file. Here's a description of the variables:

• build - compiles the app
• buildall - compiles the app separately for every device in the SUPPORTED_DEVICES_LIST, packaging appropriate resources. Make sure to have your resource folders named correctly (e.g. /resources-fenix3_hr)
• run - compiles and starts the simulator
• deploy - if your device is connected via USB, compile and deploy the app to the device
• package - create an .iq file for app store submission

To execute the run target, run make run from the home folder of your app
