Writing Documentation

To read documentation, go to docs.civicrm.org for the most high-level list of all active documentation.

This page describes the details of the documentation systems within CiviCRM and how to contribute. We also have a more [basic overview] (https://docs.civicrm.org/user/en/latest/the-civicrm-community/contributing-to-this-manual/) on how to contribute to this guide or the user guide.

Note: the wiki is not covered here

The wiki has historically been CiviCRM's documentation system but is currently being phased out. As of early 2017, documentation is still somewhat split between the wiki the the guide books described below, but we are working to eventually consolidate all documentation into guide books. A migration process is currently underway for this Developer Guide, and a process will likely follow for a dedicated Administrator Guide, as well as extension guides.

The rest of this page describes guide books only and does not cover documentation processes that involve the wiki.

Guide books in MkDocs

We are using MkDocs to produce books. The content for each of these books is written in markdown, stored in text files, and hosted in a repository on GitHub. Then, the books are automatically published to docs.civicrm.org using our custom publishing system.


In an effort to maintain documentation anchored to specific versions of CiviCRM, some books store separate versions of the documentation in different branches within the repository.

If you're improving current documentation, please edit the master branch, which will be periodically merged into other branches as needed.

In rarer cases, if you have an edit that pertains to a specific version, (e.g. documentation about a feature in an older version of CiviCRM, which does not require documentation in the latest version), then please edit the branch corresponding to that version.


A book can have multiple languages, and we use separate repositories for different languages. For example, you can click See all X editions and find the repositories for additional languages.

Contributing to documentation

We welcome contributions, small and large, to documentation!


Before diving into editing, you may find helpful information within the following resources:

Submitting issues

The simplest way to help out is to describe a change that you think should be made by writing a new issue in the issue queue for the GitHub book you are reading. Then someone will see your issue and act on it, hopefully fast. Each book has its own issue queue. First find the GitHub repository for the book (listed in the above table), then when viewing on GitHub, click on "Issues". You will need an account on GitHub to submit a new issue, but creating one is quick and free.

Editing through GitHub

Please see the documentation for editing with Git in the CiviCRM user guide.

Testing locally with MkDocs

The most advanced way to work on a book is to use git to download all the markdown files to your computer, edit them locally, preview the changes with MkDocs, then use git to push those changes to your personal fork, and finally make a "pull request" on the main repository. This approach makes editing very fast and easy, but does require a bit of setup, and some knowledge of how git works.

  1. Install pip (python package manager)

    • OS X: brew install python
    • Debian/Ubuntu: sudo apt-get install python-pip python-wheel
  2. Install MkDocs, plus the Material theme and the Pygments syntax highlighter.

    sudo pip install mkdocs mkdocs-material pygments pymdown-extensions
  3. Obtain the source files for the book you want to edit

    1. Find the repository on GitHub (see "repository" links above, or the "GitHub" link on the bottom left of screen of the documentation you are reading)
    2. Fork the repository on GitHub.
    3. Clone your fork of the repository to your computer

      git clone https://github.com/YourGitHubUserName/civicrm-dev-docs.git
      cd civicrm-dev-docs
  4. Launch a local copy of the book

    1. Run:

      mkdocs serve
      • If you get [Errno 98] Address already in use then try using a different port with mkdocs serve -a localhost:8001
    2. View through your browser at http://localhost:8000.

  5. Edit the markdown with an editor of your choice. As you save your changes mkdocs will automatically reprocess the page and refresh your browser.

  6. When you are happy with your edits, use git to commit and push your changes up to your fork. Then submit a pull request on GitHub.

Adding a new page

  1. Make sure you are already set up to edit locally with MkDocs
  2. Decide where it should go in the menu. (Ask for advice in the documentation channel if you're unsure.)
  3. Add a menu location for the new page by adding a new line appropriately in mkdocs.yml.
    • Follow the pattern you see on other lines of this file to specify a title and a file location.
    • When setting the title, keep in mind that the same title will display in the menu and in the reader's browser tab title, so choose a title that's short but that also stands on its own to some extent.
    • Specify a location for the markdown file for your new page which follows the folder structure of the menu location you decided on.
  4. Add a new markdown file in the location specified by your new menu item and begin add content to it.
  5. If you're copying existing content from other sources (e.g. wiki, StackExchange, etc.) then follow the instructions for providing attribution
  6. If you're migrating one whole wiki page, follow instructions for redirecting a wiki page to MkDocs.

Content attribution guidelines

All CiviCRM documentation content is licensed CC BY-SA 3.0. This means that if you want to copy content out of our docs and use it elsewhere, you're welcome to do so as long as your give attribution to the author.

How to obtain author information for content within our books

This is relevant when you want to copy content out of our documentation books.

  1. Find the GitHub repository for the book that contains the content you'd like to use. (There will usually be a link to this repository at the top right of ever page.)
  2. Navigate to the corresponding markdown file within GitHub (it will match the URL path of the published content).
  3. Click on "Blame" to see detailed information about content authors, line, by line.

How to displaying attributing for content migrated into our books

The CiviCRM wiki and Stack Exchange also use the CC BY-SA 3.0 license, which is convenient because content is regularly migrated into our MkDocs books from these sources. But to comply with the license, we must attribute the original content authors

When migrating content into our docs books which requires attribution, display this attribution at the bottom of the page as follows:

## Credits

Some content from this page was migrated from other sources
and contributed by the following authors: 

* Mickey Mouse
* Lisa Simpson
* Big Bird

Commit messages should also reference the URL of the original content.
