As promised, Bart takes us through the final step in our GitHub journey - learning how to contribute to an open source project. He explains three open source scenarios: using someone's code exactly as-is, using their code with a few customizations of your own, and finally the most interesting scenario, customizing the code and contributing your customizations back to the project.

When he gets to the final scenario, he gives us a way to practice these newly-acquired skills, and it's something he's wanted to do for a long time. He's created a gallery for all Programming By Stealth listeners to contribute their work they've done in the various challenges we've worked in Programming By Stealth. If you have your code from the challenges for Conway's Game of Life, the number guessing game, the currency converter, the currency grid, the world clock or the time sharing clock, we'd love to have you contribute to the PBS gallery to show off your work.

Bart explains that the GitHub Pages he's created will allow us to fork his code, make our own changes, and then create what's called a pull request to get them accepted into the official PBS Gallery at gallery.pbs.bartificer.net. I worked through the process for one of my projects and it was definitely a learning experience, which is the whole point of Programming By Stealth.
