 ## Docker run script
 ```
 docker run -d   -p 80:8484   -e GRIST_PUBLIC_URL=http://<URL>   -e GRIST_SQLITE_DB=/var/lib/grist/grist.db   -e APP_HOME_URL=http://<URL>   --name grist   gristlabs/grist-oss

 This creates a functioning anonymous instance with no login auth defined. Unclear of how users are managed, maybe all in cookies, does weird stuff like giving user named like @guest and @you (possibly to multiple users simultaneously). Multiple people can edit the same table, data will update to other user, but there's no notification of collaborative editing: no user list, and no cursor to show what other user is doing.
