Put that after TEXT in your Conky config file and you'll be away! The only thing to change is the "fold -sw 85" bit...Change the 85 to the number of characters you want to wrap the text by, or delete from "|" all the way to the end if you want it all on one line.
You're welcome to use any of the configs I've posted here, that's what they're here for!
As far as getting started, your config file will be in ~/.conkyrc. If you can't find it, it means that there isn't one set up yet! For first steps, I recommend checking out Conky Hardcore: [link]
There are loads of different options, so really the sky's the limit in terms of what you want to do with it, although it can be a little tricky to learn the context. Most of us super-users have simply learned over time, stealing snippets of code here and there, and then just getting creative!
