 Hi, I'm Dazza Greenwood, a scientist at MIT Media Lab. I run law.mit.edu. And this is a little kudos video for the first student in the computational law course of 2019 to contribute content to our course page by making a pull request in GitHub. GitHub is where we keep all the course materials, and we use GitHub pages to make our static websites. So it's displayed in an easy way. Let me show you exactly what I'm talking about. Here we go with the screen share. OK. Here is the pull request that Raina made. You can see what we used to have was what is blockchain to be announced. And she basically added this proposed content, which is a link to a kind of a fun video game that uses so-called crypto zombies to explain the concepts. We accepted the pull request, which is called merging it. And if we scroll down here to, here we go, what is blockchain? Right here is the link. So you can kind of click the link, and it's working. We had to do a little bit of cleanup on the markdown syntax, but it's perfectly fun and interesting material. So as a reminder, when you're making contributions to law.mit.edu materials, we do so under open source licenses. And if you look at our repository and scroll down to the license, you can see we're using a standard open source license, the MIT license. These are the flat files in the repository. And they're also displayed using, as I said, GitHub Pages in a nice formatted HTML display format. So kudos. Thanks, Raina. And we encourage contributions from any other student that has some materials that you think would be good contributions for the class.
