I am not sure why I started using Knockout, but I have had an overall positive experience with the framework. I was very intrigued with their hands-on tutorials built into the site, which made getting started fairly easy. I walked through them step-by-step, writing out all of the code examples by hand, and diligently debugging typos when the example would not execute as expected. From there, I took the simple step of starting a small side-project just to see how it would all interact. At that point, it became quickly obvious that the tutorials suck and are missing large pieces of information that are vital to get just a basic application going. I also found that there are two tutorials that are completely worthless in terms of getting start - they are advanced topics that I still have not found an applicable usage.
The GitHub wiki is sparse and filled with many empty templates. The information is not reliable - I am not sure how much of is it accurate as of Knockout 3.1. So, I am working on slowly putting together better documentation. As I discover something new or expand on something I already know, I am adding it all to a little sidebar of notes that I keep. My hope is that I will get enough information that I can meaningfully contribute to the wiki. I like this project, and it is clear that plenty of other people like it. I just wish the difficulty to realistically get started was a little lower.
I am trying - this is going to be my first little tiny toe dipping in the big ocean of open source development. We shall see how it goes.
