Thermal Pad/Vias

Hey, I'm using a chip (BQ24092DGQR) with a thermal pad underneath. How will I go about designing it? Do I just have a large area underneath it with just top paste layer, for creating the thermal pad? Also the datasheet mentions thermal vias...are they just normal vias in Altium? I put the datasheet below:

There's a video awhile back, is this related to my question?

TIP #014: If you have an exposed pad on your component, consider breaking solder paste into smaller pieces.Why? It helps during soldering.Would you like to s...

Yes, You need to connect the Thermal pad to the VSS(GND)using via.
Yes Robert's video is related to that.
You can also have a look at the Evaluation board Layout (http://www.ti.com/product/BQ24092/toolssoftware) and also look at the 12. Layout section of the data sheet(Page No 28)
Thank you.

- I would follow footprint and paste recommendations from the datasheet you attached
- I am speaking about exposed pad and footprints in this video: https://www.youtube.com/watch?v=cMxXea16Hxc
