Welcome to the official home of the WordPress documentation team.
This team is responsible for coordinating all documentation initiatives around WordPress, including the Codex (moving to HelpHub and DevHub), handbooks, parts of developer.wordpress.orgWordPress.orgThe community site where WordPress code is created and shared by the users. This is where you can download the source code for WordPress core, plugins and themes as well as the central location for community conversations and organization. https://wordpress.org/, admin help, inline docs, and other general wordsmithing across the WordPress project.
Want to get involved?
There are many ways in which you can help the Docs team. Every small contribution counts and helps! You can report an issue or typo you found in the docs, or even help us write new documentation for parts that are still missing. These are some helpful links to find out more about what we do and how to collaborate:
