bin/init creates three files:
It also generates
OVERLEAF_INVITE_TOKEN_SECRET in config/variables.env. Keep it, and do not publish this file or commit it to version control.
Keep the version that the Toolkit selects for a new installation. To change the version of an existing instance later, follow Upgrading your deployment.
bin/init does not overwrite existing configuration. If it reports that files already exist, inspect them before continuing. Keep config/ and data/ when restarting or upgrading the instance.
