Red development starting documentation.
Because very few people are actually contributing to the Red source, I decided it was time to put some information in a document to save every new programmer some time in researching the Red sources and give a helping hand in understanding how the Red Programming Language sources work together.
You are free to join the effort at its new home: https://github.com/reddoc/develop
Be sure to take a look at the wiki there!
