Help information is typically pretty extensive. If you'd like to make the information more readable, you could always pipe the result to the old-fashioned more.com:
Get-Help Get-Process -detailed | more.com
However, a much better (and shorter) way is to remove the "Get" like this:
Help Get-Process -detailed
Help is a pre-defined function that calls Get-Help and automatically appends a pipe to more.com.
