Merge branch 'patch-1' into 'master'

fixed Windows commands in SSH Help.

The current commands shown don't work in Command Line, or PowerShell. Command Line doesn't recognize the `~` character as the home directory, the `<` character is reserved in PowerShell, and `cat` doesn't work in Command Line. This commit provides commands that will work for both the Command Line, and PowerShell.
