I was expecting a link to the data sheet which tells how it works, rather than a video that shows what it can do.
It's using I2C communications, so writing a library isn't that hard. Just tedious (data sheet p.21 onwards).
It's using 3.3V so if you're using a 5V Arduino, make sure you connect it properly and add level shifters. Other than that the only other external components you need other than the sensor itself are two caps for power supply decoupling and filtering.
The largest problem is the package (only WSON and WQFN available) which are pretty much impossible to hand solder to a breakout board. Luckily you can apparently get sockets for the WQDN version:
