RCBasic is an open source project and as such is a community effort. If you wished to get involved to make RCBasic even better here are a number of ways you can help the project evolve.
Contribute Code
If you know C++ and are familiar with SDL2, you can download the source code from the github page here: http://github.com/n00b87/rcbasic3. Try to familiarize yourself with the code and see if you can find some of the bugs listed on the forum or if you can implement a new feature from the feature request.
Contribute Documentation
There are still a lot of functions and features that are either not documented or need improved documentation. The documentation is in HTML files so just find the HTML file in the documentation folder that has the specific feature you want to improve on or create a new html file to add to the documentation.
Demos, Examples, and Tutorials
The more material available to show off RCBasic’s capabilities the better. In addition we need more learning material to attract new users. If you are a good writer and/or content creator then this could be right up your alley.
