After creating or modifying a CSL style, consider sharing your new style if it might be of interest to other users (e.g. if the style is for an academic journal, publisher, university, or university department). The easiest way to share your style is via the Zotero Style Repository. To submit styles to the repository, follow the instructions below.

• The file name the style should contain no characters other than lowercase roman letters (a-z), digits (0-9) and single hyphens (-). The file extension should be ”.csl”. E.g. use “style-name.csl” instead of “StyleName.csl”, “Style Name.csl” or “style_name.txt”.

• The style ID (set with the <id> element) should be of the form http://www.zotero.org/styles/file-name, without an extension (e.g. http://www.zotero.org/styles/apa for apa.csl).

• The style should include a license (set with the <rights> element) that permits sharing (most styles use the Creative Commons Attribution-Share Alike 3.0 License). E.g. use

  <rights>This work is licensed under a Creative Commons Attribution-Share Alike 3.0 License:
  http://creativecommons.org/licenses/by-sa/3.0/</rights>

• If your style is largely derived from an existing style, list the authors and contributors of that style as contributors in your style. Add yourself as the style's author.

• Make sure your style validates.

The easiest way to submit styles is post a link to your style code on the Zotero forums. Please do not paste style code directly into your post. Instead, use a code sharing website like http://gist.github.com.

Go to the https://gist.github.com/ website, and copy and paste your style code into the large text box. Enter the file name of the style in the “name this file…” text box, and click the “Create Public Gist” button at the bottom of the page.

Create a new thread for your style in the Citation Styles category of the Zotero forum. In your post, ask for your style to be uploaded to the repository, and provide the link to the Gist (copy the URL from the address bar, which should be in the form of https://gist.github.com/766801. Your style will then be added to the repository by one of the Zotero developers or community members. If you don't hear back within a week, post a reminder to the same thread.

While the process is slightly more complicated, you can also add styles to the repository yourself using the Zotero SVN. For that, you first need to register for a Zotero SVN/Trac account. Next, you will need an SVN client. Many users prefer GUI-based SVN clients like Tortoise SVN for Windows, Versions (commercial) for Mac, and Rabbit VCS for Linux. Check out the csl directory (https://www.zotero.org/svn/csl) with your SVN client, add and commit your style. Note that styles won't immediately appear in the repository (the repository is manually updated, which can take up to 24 hours).
