Remove a line from a CSV powershell
===

I currently have the following csv

    These, Are, Several, Columns
    -----, ---, -------, -------
    "And", "here", "is", "data"
    "And", "some", "more", "data"

While I wish I could simply change the process that creates the csv to remove the line of dashes that isn't possible.

The line of dashes is always the 2nd line, can I use powershell to remove the 2nd line of data?

Bonus question, I'm looking to add at the bottom a blank line, followed by a paragraph of text. I'm guessing I would be able to use the add-content cmdlet, but I'm not entirely sure how.
