 # build-gn
 
-This is a minimal bootstrap environment for building GN, you can also use it
-as a full functional environment for building any project using the `base`
-library.
-
-This repo is forked from [yue/yue](https://github.com/yue/yue) with all Yue
-related history stripped.
-
-## Goal
-
-The goal of this project is to provide a standalone version of GN with preset
-Chromium build configurations, which can be used to setup projects without
-requiring fundamental build files to exist inside the projects.
-
-Changes to GN can be found at [yue/gn](https://github.com/yue/gn).
+This is a modified version of GN that provides Chromium's build configurations
+as builtin rules, which can be used to build any project.
