Strange guide: 'remove from launchpad' vs. 'delete from launchpad'

It is called "how to remove app from launchpad" but actually talks about deleting the app by means of launchpad. So how these actions are actually done? I mean, there's a lot of apps I do not need in the launchpad - like small utilities I rarely use. Yes, i know I can arrange them into folders and move these to some pages of the launchpad, but still. If they write "remove from launch pad" there must be a way to do exactly that.

Strange article in general. Even the word 'from' changes it's meaning throughout the text.
