 GN is a meta-build system that generates [Ninja](https://ninja-build.org)
 build files so that you can build Chromium with Ninja.
 
-## Why did you switch from GYP?
-
-1. We believe GN files are more readable and more maintainable than GYP files.
-2. GN is fast:
-  * GN is 20x faster than GYP.
-  * GN supports automatically re-running itself as needed by Ninja
-    as part of the build. This eliminates the need to remember to
-    re-run GN when you change a build file.
-3. GN gives us better tools for enforcing dependencies (see
-   `gn check` and the `visibility`, `public_deps`, and `data_deps`
-   options for some examples).
-4. GN gives us tools for querying the build graph; you can ask
-   "what does X depend on" and "who depends on Y", for example.

-## What's the status of the GYP->GN migration for Chromium?
-
-_As of Oct 2016:_
-
-  * All of the Chromium builds have been switched over.
-  * Nearly all of the GYP files have been deleted from the Chromium repos.
-  * You can no longer build with GYP as a result.
-  * There are still some GYP files in place for the "Closure Compilation"
-    builders that need to be converted over.
-  * Some related projects (e.g., V8, Skia) may still support GYP for their
-    own reasons.
-  * We're still cleaning up some odds and ends like making gclient not
-    still use GYP_DEFINES.
