Getting Started

So you want to contribute to ChooseALicense. Great! We welcome any help we can get. But first, please make sure you understand what this site is all about. It’s not a comprehensive list of all possible licenses.

Adding a license

Choosealicense.com is intended to demystify license choices, not present or catalog all of them. As such, only a small number are highlighted on the home page or https://choosealicense.com/licenses, and there are several requirements for a license to be cataloged on the site:

1. The license must have an SPDX identifier. If your license isn't registered with SPDX, please request that it be added.
2. The license must be listed on one of the following approved lists of licenses:
   • List of OSI approved licenses
   • GNU's list of free licenses (note: the license must be listed in one of the three "free" categories)
   • Open Definition's list of conformant licenses (non-code)
3. A GitHub code search must reveal at least 1,000 public repositories using the license
4. Identification of 3 notable projects using the license with straightforward LICENSE files which serve as examples newcomers can follow and that could be detected by licensee if it knew about the license

If your proposed license meets the above criteria, here's a few other things to keep in mind as you propose the license's addition:

• Is the license already cataloged? See https://choosealicense.com/appendix/ for a list of all of the licenses known by the site.
• Licenses live in the /_licenses folder.
• The license files should be in the format of _licenses/[lowercased-spdx-id].txt (e.g., _licenses/mit.txt)
• Each license has both required and optional metadata that should be included.
• The text of the license should be wrapped to a 78 character width.
• The text of the license should match the corresponding text found at https://spdx.org/licenses/
• The body of the file should be the text of the license in plain text.
