The idea of extensive and easy to use documentation is at our forefront. This is still a WIP and there’s more to come. If you need certain things now see the R5RS document for basic Scheme primitives used as a part of our prelude along with the Gambit Manual for our underlying implementation internals.
To propose a documentation change, edit the colocated .md file in the Gerbil repository and submit a pull request. Reporting an issue also helps.
When information is missing, out of date, or unclear, it’s a bug! If you cannot edit try to contact us (by email, on Gitter or GitHub, etc.) and we’ll get it done.
