Random content in Custom Content Dashboard Widget?


As Custom Content Dashboard Widget don't allow us (maybe it allows, but talking about "without coding") several widgets, it would be useful it to show random content, like Admin Panel Tips. Are there any ways to do so?

By the way, I'll ask here - That tutorial on plugin's installation isn't enough for me unfortunately :slight_frown:

Can you explain me how to set up this Custom Content Dashboard Widget in few steps?
