You’re using an open source project, so you can’t expect the same kind of service as a paying customer.
Regarding getting help on a community mailing list, I’d really love if people could be good open source citizens and help each other as much as them demand help from others. Sadly, that’s not how things work and such help comes when it comes.
What’s for sure is that ranting won’t make things happen any faster.
Regarding documentation, it lives in the repository along with the source and can be contributed too.
Thank you for the response, I try to understand the documentation, do some moves but t doesn’t work. If I find the solution of course I will publish it.
