Versioning is a method I use to take extra care of any changes made to your website's codebase. I can make small, step-by-step changes that can then be tracked, documented, and easily rolled back if bugs or issues occur after I make changes to your website. This ensures, among other things, that the code remains transferable and sustainable. GitHub is one of the popular Git version control system on which it can run which is already used by over 40 million programmers worldwide.
