Here is the material from my presentation on Introduction to PowerShell at the first Montreal PowerShell User Group meeting that occurred yesterday (2015/09/15).
The Powerpoint presentation and PowerShell code is available on the meetup group page and Github:
Even thought I was a bit stress to present, I really loved the experience and I can't wait for the next meeting! We had a great group (17 people) who showed great interest and asked tons of questions!!
The next meeting will probably occur around the end of October.
