The Confluence Publisher allows documentation written in AsciiDoc and versioned directly with the documented code base to be published to a Confluence space.
It converts the resulting AsciiDoc HTML output to XHTML compatible with Confluence, manages included resources as Confluence attachments and ensures that only content modified since the last publication is again re-published.
The documentation of the current release version is published to https://confluence-publisher.atlassian.net/.
JetBrains kindly supports the core developers with free open-source licenses for their products.
