At this point you’ve identified a problem, defined a solution, and mocked up wireframes to show how the solution works.
Parts 3 and 4 dive into the more technical aspect of an Appathon. It assumes a degree of understanding of code (or at least a willingness to start the learning process). You may need to reference resources such as code.org, codeacademy, w3schools, and the like.
If you’d like to participate in the development steps, continue on! If not (due to any variety of reasons), head to the demo slam.
