Installing NodeBB on the server with MongoDB database
Is there anything else that I need to follow to host NodeBB on digital ocean with mongodb as database?
I m reading through the NodeBB docs and following the links by order but was wondering is there anything else that I need to know about?
And the digital ocean guide is 2 years old and wondering if there's changes in things that I m not aware of.
