We tried to use locally installed sharelatex instead of our SVN papers repository in our research group. Good god, did we switch back really quick - not only the install process is godawful (no proper docs, outdated instruction, outdated dockerfile, missing docker-compose, took me a week to figure it out), absence of any stability along with zero way to administer it properly (no UI for users management, you have to send commands through shell to provide admin rights) just killed it for us. :\
