Here's a tutorial on the wiki: Coding-tutorial. I also fixed the link in there, so can watch a video tutorial if you want. I'm not sure how good the video is, I didn't watch it. The wiki is outdated too though. If you need any more help or are confused by something the wiki/video says, you can just ask here.
@juice(View Post) You need to get the source and then follow this tutorial. I don't think you understand what you would need to do to make elements, though, you have to edit the source code and compile it. Do you know c?
