Christophe Porteneuve explains and demonstrates how to help with the documentation of the Prototype framework, be it reference API documentation or more tutorial-oriented material, either by fixing issues with existing docs, updating docs to reflect the latest version, or creating new material altogether. The session covers the whole process, from grabbing the source for existing docs to testing your contribution to submitting it and getting it approved, using tools and systems such as git, diff, the upcoming PDoc system and the framework's GitHub repository.
