No, you cannot.
NodeBB based on Node.js and you need access to Node.js and npm to configure Nodebb
I need a step by step guide on how to install this on my server
The instructions here https://docs.nodebb.org/en/latest/installing/os/ubuntu.html are extremely unclear. Please help me and yes i do have ubuntu 14.01 installed. Also i dont want to use MongoDB. Much love
Still not sure why these french docs are in English, but they seem to be mostly up to date.
