# Contributing to SuiteSparse To add an issue for a bug report (gasp!) or a feature request, you can use the issue tracker on github.com, at [`https://github.com/DrTimothyAldenDavis/SuiteSparse/issues`] (https://github.com/DrTimothyAldenDavis/SuiteSparse/issues). To contribute code, you can submit a pull request. To do so, you must first agree to the Contributor License Agreement [`CONTRIBUTOR-LICENSE.txt`](CONTRIBUTOR-LICENSE.txt). Print a copy of the txt file (as a PDF), sign and date it, and email it to me at DrTimothyAldenDavis@gmail.com. Pull requests will only be included into SuiteSparse after I receive your email with the signed PDF. Do not submit a pull request to the default branch. Instead, use the dev or dev2 branches.
