Uploading Code Pkg to GitLab from Windows


I am newbie to GitLab. I am currently working on a webapp project and would like to use GitLab for the same. I want to use the version control and WebIDE on GitLab to begin with.

I am on Windows 10, and downloaded(FTP) the webapp code pkg from the webserver(thirdparty, and no integration with GitLab) onto my local Win10 machine. I have read a few post here which say GitLab installation on Win10 is not the best idea.

Looking for help to bulk upload the whole pkg and create a new project repo onto GitLab. Also is there a better pipeline for doing this. (Barring a Linux OS or VM)
