Hi there
Good to see you have got your frame and are staring the build.

Yes it's a 11/8" Threadless/Ahead type.
You will need to decide what forks and stem you will be using so you can work out the steerer tube length and stack height you will need.

There are a few good descriptions of how to do this job on Park Tools and Cane Creeks or other headset makers sites.

If you are unsure get a pro to fit it if you get your sums wrong you might ruin a set of forks or your frame.

It is a simple job but take your time.

I would recommend a sealed cartridge type bearing headset
