The first of four episodes of Epix’s “Road to the NHL Winter Classic” premieres Tuesday at 10 p.m. on Epix and various places online. In case this is the first you’ve heard of the series, or Epix, or both, here’s a quick primer, including how to watch:

What is “The Road to the NHL Winter Classic”?

It’s a four-episode series that takes viewers behind the scenes with the Capitals and Blackhawks leading up to and through their outdoor hockey game on New Year’s Day at Nationals Park. It will be similar to the popular “24/7” series produced by HBO in three of the last four years. The Capitals and Penguins were featured in that series leading up to the 2011 Winter Classic. Ross Greenburg, who created “24/7” while he was president of HBO, is leading the project for Epix. Each episode is an hour and the show will feature ‘unfiltered language.’

When will the show air?

Episode 1 – Tuesday, Dec. 16, 10 p.m.
Episode 2 – Tuesday, Dec. 23, 10 p.m.
Episode 3 – Tuesday, Dec. 30, 10 p.m.
Episode 4 – Tuesday, Jan. 6, 10 p.m.

Wait, what is Epix?

It’s a cable TV channel that mainly shows movies and is available in about 50 million households nationwide.

Do I get Epix? 

I’m not sure. I have no idea if I get Epix. The channel is available through these providers. Epix is not available for DirecTV or Xfinity (Comcast) subscribers. But don’t fret!

How can I watch “Road to the NHL Winter Classic” if I don’t get Epix? 

You can either order Epix through your provider, or — and this is probably the better option — watch for free on EpixHD.com, NHL.com and MonumentalNetwork.com. (Update: If you sign up for an Epix free trial here, you can watch episodes on-demand.)

I can watch for free?

Yes. Every episode will be streamed for free online.

What if I don’t want to watch on my computer?

There are free Epix apps available for Roku, Apple TV, XBox, PlayStation, Kindle Fire and other streaming players and devices.

What’s the first episode about?

Again, I’m not sure, but it will touch on Capitals Coach Barry Trotz’s relationship with his son Nolan, who has Down syndrome. In the clip below, Trotz takes a trip to the National Zoo with his wife, Kim, and Nolan.
