 ## Native-Comp
 
-Building a Emacs.app with native-comp support
-([gccemacs](https://akrl.sdf.org/gccemacs.html)) from the `feature/native-comp`
-branch is now supported without much hassle thanks to the newly released
-`libgccjit` Homebrew formula.
+_Note: On 2021-04-25 the `feature/native-comp` branch was
+[merged](http://git.savannah.gnu.org/cgit/emacs.git/commit/?id=289000eee729689b0cf362a21baa40ac7f9506f6)
+into `master`._
 
-To build a Emacs.app with native compilation enabled, simply run:
-
-```
-./build-emacs-for-macos feature/native-comp
-```
+The build script will automatically detect if the source tree being built
+supports native-compilation, and enable it if available. You can override this
+to force it on/off by passing `--native-comp` or `--no-native-comp`
+respectfully.
 
 By default `NATIVE_FULL_AOT` is disabled which ensures a fast build by native
-compiling as few lisp source files as possible to build the app. Any remaining
-lisp files will be dynamically compiled in the background the first time you use
-them. To enable native full AoT, pass in the `--native-full-aot` option.
+compiling as few elisp source files as possible to build Emacs itself. Any
+remaining elisp files will be dynamically compiled in the background the first
+time they are used.
 
-On my machine it takes around 10 minutes to build Emacs.app with
-`NATIVE_FULL_AOT` disabled. With it enabled it takes around 20-25 minutes.
+To enable native full Ahead-of-Time compilation, pass in the `--native-full-aot`
+option, which will native-compile all of Emacs' elisp as built-time. On my
+machine it takes around 10 minutes to build Emacs.app with `NATIVE_FULL_AOT`
+disabled, and around 20-25 minutes with it enabled.
