How to setup config for gitlab?

Question

git

Used the official instructions to set it up. Key generated. I don't understand how to configure config.
Here is my file:

[core]
  repositoryformatversion = 0
  filemode = true
  bare = false
  logallrefupdates = true
[remote "origin"]
  url = https://gitlab.com/artem-solovev-lse/notepad.git
  fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
  remote = origin
  merge = refs/heads/master
