Alpine License information

Please provide license information about how Alpine is distributed. What are the allowed licenses for the base OS (kernel and default packages) and what licenses are used when distributing applications developed by the Alpine Linux team.

If possible please also provide information about packages distributed through Alpine’s package manager in the official repositories.

A public statement would be nice (similar to https://www.debian.org/legal/licenses/) but an official comment or LICENSE file in the source code repositories should suffice.

Thank you
