License
Licensing is legal documentation that lets you form agreements with other parties over how they use and distribute your copyrighted works. A typical software license grants the licensee, typically an end-user, permission to use one or more copies of the software in ways where such a use would otherwise potentially constitute copyright infringement of the software owner's exclusive rights under copyright. You could refer to your software license here and reference the users to read the complete license information elsewhere in an appendix or other related documents.
