key points:

• The LICENSE, LICENSE.md, or LICENSE.txt file is often used in a repository to indicate how the contents of the repo may be used by others.
• People who incorporate General Public License (GPL’d) software into their own software must make their software also open under the GPL license; most other open licenses do not require this.
• The Creative Commons family of licenses allow people to mix and match requirements and restrictions on attribution, creation of derivative works, further sharing, and commercialization.
• People who are not lawyers should not try to write licenses from scratch.
• Add a CITATION file to a repository to explain how you want your work cited.
