I've posted in this forum and it's a suggestion of OnlyOffice overall, not each specific part.
1.You need to do more with the RPM/Deb versions, provide versions for all of it so it can be done via RPM/Deb rather than just docker. In recommending Docker, you are forcing people to learn 2 systems, 1 being docker, the other being your own software, I get it's easier for you to deploy but it's not easier for people who have never used docker.
2. Your one-click installer doesn't recognize 64bit CentOS 7 even though this is now using the 3.10 kernel as you recommend/require, when trying to install on CentOS 7, it returns saying that we must use 64bit OS but it is. Again, emphasizing on the learning 2 systems, you're forcing people to learn ubuntu/debian when their preferred operating system may be CentOS, all Linux are the same but do act differently.
3. For those of us that aren't familiar with Docker and not many people are, provide more documentation on this so we can understand how to do things more.
