Fab-manager is a great software, however it is rather hard to install for non-technical people. For the technical people installation via Docker presents security risks and this causes the delays in decision making.
I believe for mass adoption and world wide increase usability of fab-manager, the development team has to be more client-focused other than product based. There are so many things the development team assumes the customers know like knowledge of ruby and advanced linux.
Thank you
