What is Git?
Git is a free and open-source distributed version control system initially developed by Linus Torvalds, who also developed the Linux kernel. Some WordPress developers have informally used Git for WordPress development citing its distributed nature, ease of branching and merging and increased speed over the generally community accepted Subversion. However, this is the first time Git has been fully integrated with a WordPress Hosting Platform.

The benefits…
You don't have to be a Git wizard to deploy your application to WP Engine, but knowing the ins-and-outs of Git is certainly helpful. Once you’re set up, you will be able to deploy updates to your WP Engine hosted application with ease, as well as show differences between your local source code and your production or staging site. No more dragging and dropping of files via SFTP, and no more "Cowboy Coding"!
How can I get started?
Current WP Engine customers can get started by logging into our support site and opening a support request that includes your application/install names as well as your SSH public key, and the SSH public keys of anyone you'd want to provide access to, like your team members, for example. We'll need to first verify proper ownership/permissions to access the account in general, so if you aren't listed as a user for the account in the My WP Engine portal, we won't be able to provide access to that account.

At long last…
