Instructions on how to build packages yourself #1
Description
In order to promote users to be independent, i.e. to allow them to operate even when we are slow or defunct, users should be able to build packages themselves. Avoiding vendor lock-in, so to say. We should have better documentation on how users can build packages themselves.
This does not include instructions on how to build for a different Ruby or Jemalloc version. That would be part of the developer/contribution documentation.
