git want to push a file to a repository in gitlab that already has files in it

Need some help with git; I have a folder that is on nearly ANY of my workstations and I have SEVERAL and would like to keep it synced. The name of the REPO is Documents. In my online [login to view URL] there is Documents and want to ensure this is on EACH of my workstations. As a result the “same” Documents will always be synced? There is file in both locations that I don't want to lose. So here is the ‘ASK’ for this project, if I come to a new workstation, what are the steps that I must go through to as a “git clone” will FAIL because there is an existing “Documents folder”. cd cd Documents git init git remote add origin git@[login to view URL]:ejbest/documents git add -A git commit -m “get them uploaded” git push –set-upstream origin master ERROR: Please make sure you have the correct access rights and the repository exists. git clone and proves the access rights work with my key set to 400 Please share the steps to “git init” the remote folder “Documents” with my local “./Documents”? want to push a file to a repository in gitlab that already has files in it I will pay promptly and left nice feedback and 5 stars
