The OPNsense project wants to be a project that is friendly for users,
developers and partners. In this world with trademarks and copyright it
is best to “keep things as simple as possible, but not simpler”. Below
we pointed out the Licensing and Trademark rules we use.

want to do with the code, even fork it and take it from there.
