Updating document

This guide explains the organization of Pulsar documentation and website repos and the workflow of updating various Pulsar documents.

Source repositories

Currently, the source of documents and website (where the docs are finally published) are located at the apache/pulsar-site repo.

Update versioned docs

Documentation should be up to date for all actively supported versions.

No need to update documentation for versions that are not actively maintained unless the documentation is incorrect.

To update versioned docs, go to versioned_docs folder.

For versions prior to 2.8, Pulsar releases versioned docs for each patch release. You can update the exact versioned doc.

For versions start from 2.8, Pulsar release versioned docs for each minor release. Apart from updating the content, you should take care of adding specific instructions.

For example, if you want to add docs for an improvement introduced in 2.8.2, you can add the following instructions:


This <fix / improvment> is available for 2.8.2 and later versions.


Update reference docs

If you want to update Pulsar reference docs, you should update the corresponding source files.

  • Some reference docs are generated from code automatically. If you want to update the docs, you need to update the source code files.
  • Some configuration docs are updated manually using markdown files.

Update configuration docs

Docs for configs of bundled components are generated from command-line tools automatically:

Docs for configs of external components (whose source code is hosted outside the Pulsar repositories) are updated manually:
