As you can see, all this information is available to you.  This will help you understand how to write functions, how to use operators, Aliases, Parameters, Hash Tables, and more.  Don’t be intimidated by all this information.  I recommend you to use “Help” and then you can search on the internet or reading a book for more in depth information.

By the way, this information can be found online under Microsoft TechNet.  Here an example link looking at the Help on “About_Operators”: http://technet.microsoft.com/en-us/library/dd347588.aspx

You will find there’s a total of 95 topics.  This is only the “About_*” topics.  So, as you can see,  this information is available at your fingertips.  So, use it and start learning Windows PowerShell.
