This wiki is about anything even remotely related to the programming language Scheme (see what-is-scheme) and the people that use it. That is a very general statement, and this wiki is meant to be very general. It's for, by and about the community that has evolved about Scheme. There are in fact quite a few scheme-wikis out there, but they are mostly centered around the various implementations. The only one that isn't is The-Scheme-Cookbook which has a pretty narrow mission on its own. Please read the wiki-howto before editing, inform yourself about the wiki-license under which you distribute your contribution, and test in the sand-box to see how editing works.
