Keeping the written scripts versioned using a Version Control System (VCS) will allow us to track changes in the script files; this is helpful for increasing the audibility of the written code that is being used to shape your infrastructure. During the versioning process, builds can (and should) be triggered to validate the written code.

Another benefit of versioning is that you can revert changes when needed. Imagine that you are writing code to make upgrades to your servers; if an issue is introduced during this process, you can always make a rollback and keep using the last stable version while the problem is solved.
