Okay, now I actually understood what you did. Let me clarify my earlier review:

By "a README like MEgalopolis" I did not mean that you should copy the README
file from there and string replace SMeltery with "Google Internationalisation
team", but to create a README that is conceptually the same, so it should
contain:

1) The origin/source/upstream project of the font
2) A rationale why you're including it
3) A short license information, something like "For license information, see the
LICENSE file." can be enough.

That's it. Now, let's wait for a discussion on blink-dev to see how we handle
derivative reduced fonts, as discussed on the other CL.

+
+1. OPEN FONTS PROJECT'S AIMS
+When text is rendered by a computer, sometimes there will be characters in the text that can not be displayed, because no font that supports them is available to the computer. When this occurs, small boxes are shown to represent the characters. We call those small boxes “tofu,” and we want to remove tofu from the Web. This is how the Noto font families got their name.
+
+Noto helps to make the web more beautiful across platforms for all languages. Currently, Noto covers over 30 scripts, and will cover all of Unicode in the future. This is the Sans Latin, Greek and Cyrillic family. It has Regular, Bold, Italic and Bold Italic styles and is hinted. It is derived from Droid, and like Droid it has a serif sister family, Noto Serif.

+2. LICENSE AND OPENSOURCE
