There is now documentation!
So, be sure to check it out. If you haven’t been exposed to Cocos2D HTML, it is an HTML port of the popular cocos2D library. You can check out a series of tutorials on this site, with more coming soon. You can also see a game in action right here.
If you are running a similar project, don’t under-estimate the value of good documentation, it is absolutely HUGE. So if you actually want people using what you are investing all your time into creating, consider spending some time on documentation. Kudos to the cocos2DHTML5 team.
