 Hello. I don't know if you remember Developer Diary, the last one, where I built the Chrome Dev Summit site and kind of shared the process with you. Well, I'm going to do it again. But what's different this time is that I know very, very, very little about the subject area. I'm going to be building a media app, sort of a video player, if you like, a generic one, to try and understand what goes into making, say, a video player work. And I understand that there are things like chunking that you can do to sort of do adaptive bit rates, and you can encrypt media as well. I know nothing about these things. And so not only am I going to build a progressive web app, I'm going to discover what little I know about media on the way through and share that with you. So come along for the ride that I expect. There'll be service workers. There'll be, I'm thinking, sort of full screen kind of takeover hero transitions. I'm thinking there's going to be tons of stuff. If you have any questions, things that you want me to actually cover in the videos, just drop a comment in below. Don't forget, you can always subscribe. And I will see you as these episodes start to land. Brilliant.
