Choosealicense.com is intended to demystify license choices, not present all of them. As such, there are several requirements for a license to be listed on the site:
1. The license must have [an SPDX identifier](https://spdx.org/licenses/). If your license isn't registered with SPDX, please [request that it be added](https://spdx.org/spdx-license-list/request-new-license-or-exception).
2. The license must be listed on one of the following approved lists of licenses:
* [List of OSI approved licenses](https://opensource.org/licenses/alphabetical)
* [GNU's list of free licenses](https://www.gnu.org/licenses/license-list.en.html) (*note: the license must be listed in one of thre three "free" categories*)
* [Open Definition's list of conformant licenses](http://opendefinition.org/licenses/) (non-code)
3. A [GitHub code search](https://github.com/search?q=MIT+filename%3ALICENSE&type=Code) must reveal at least *1,000* public repositories using the license
If your proposed license meets the above criteria, please follow [these instructions for adding a new license](https://github.com/github/choosealicense.com#adding-a-license). Almost without exception, new licenses should be added as hidden (`hidden: true` in the YAML front matter), such that they are directly linkable and detectable, but not otherwise listed.
For more advanced changes, check out [the bootstrap instructions](https://github.com/github/choosealicense.com#run-it-on-your-machine) in the [project's readme](/README.md).
[HTML::Proofer](https://github.com/gjtorikian/html-proofer) is set up to validate all links within the project. You can run this locally to ensure that your changes are valid:
