You can and should write comments in tour PowerShell scrips. Use the hash (#) symbol at the beginning of the line to write a comment. You can also use a multi-line comment with <# to start and #> to end.

Region

As a special feaature of the scripting environment, we can use #region and then after some code #endregion. #region and #endregion are still just comments, but a special type of comment. They do nothing towards the actual execution of the script, but exist for the programmer and reader’s benfit. Why? They are collapsable in the editor.
