“The Free Software Foundation is the principal organizer of the
GNU Project, and you can find the FSF’s guidelines on choosing an
open source license in this post. The guidelines cover how to
choose an overall license for a project, and also cover making
decisions on licensing modified versions of an existing
project.“Through the FSF guidelines, you can gain knowledge about what
Copyleft is, and it’s wise to learn more about the GNU Lesser
General Public License (LGPL), and the GNU Affero General Public
License (AGPL). t’s also worth looking into our post on the
Software Freedom Law Center’s Legal Issue Primer. It contains a
very thorough discussion of most popular open source licenses. And
you can find much more introductory material on open source
licenses in this post.”
