How are others synching their metadata changes back into their Salesforce org

Hello All,
I was wondering what are other developers using for version control and keeping their metadata synched between orgs.
Currently we a utilizing VS code and GIT which works great for working with apex classes & VF pages and this is working well but not sure how to get the changes back into the Salesforce org. There are multiple people working in these org so we want to make sure we are all on the same page and not stepping on each others work.

Thanks
M
