How to improve Powershell Code Quality

Writing code is similar to normal writing, it is important that others can read and understand your code, considering that maintaining and changing others code consumes normaly 70 to 80% the time of Developers and QA Engineers.

As Azure DevOps and windows servers continue to be used in very conservative enterprises, the need for powershell scripting increases, because it allows you to write more fine tuned pipelines for building and releasing code.
