I just published a major update to the defold.com website. Now all manuals, tutorials and the FAQ are being built from a public GitHub repo. All docs have also been converted to Markdown so they are viewable and easily edited directly on GitHub as well.
From each page, there is a link directly to the file in the repo if you wish to make edits and create a pull request.
And thanks to the fantastic effort of @kuimoani we have Korean translations of all manuals. The build system is made to support future language translations.
The repo is here: https://github.com/defold/doc
