+## Use Self-Contained Emacs.app as `emacs` CLI Tool
+
+As the application bundle is self-contained, the main executable needs to be run
+from within the application bundle. This means a simple symlink to
+`Emacs.app/Contents/MacOS/Emacs` will not work. Instead the best approach is to
+create a shell alias called `emacs` pointing to the right place.
+
+Personally I use something similar to this:
+
+```bash
+if [ -f "/Applications/Emacs.app/Contents/MacOS/Emacs" ]; then
+  export EMACS="/Applications/Emacs.app/Contents/MacOS/Emacs"
+  alias emacs="$EMACS -nw"
+fi

+if [ -f "/Applications/Emacs.app/Contents/MacOS/bin/emacsclient" ]; then
+  alias emacsclient="/Applications/Emacs.app/Contents/MacOS/bin/emacsclient"
+fi
+```
+
+Setting the `EMACS` variable to the binary path seems to be a good idea, as some
+tools seems to use it to figure out the path to Emacs' executable, including
+[doom-emacs](https://github.com/hlissner/doom-emacs)' `doom` CLI tool.
+
 ## Native-Comp
 
-To build a Emacs.app with native-comp support
-([gccemacs](https://akrl.sdf.org/gccemacs.html)) from the `feature/native-comp`
-branch, you will need to install a patched version of Homebrew's `gcc` formula
-that includes libgccjit.
+_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`._
 
-The patch itself is in `./Formula/gcc.rb.patch`, and comes from
-[this](https://gist.github.com/mikroskeem/0a5c909c1880408adf732ceba6d3f9ab#1-gcc-with-libgccjit-enabled)
-gist.
-
-You can install the patched formula by running the helper script:
-
-```
-./install-patched-gcc
-```
-
-The helper script will copy your local `gcc.rb` Forumla from Homebrew to
-`./Formula`, and apply the `./Formula/gcc.rb.patch` to it. After which it then
-proceed to install the patched gcc formula which includes libgccjit.
-
-As it requires installing and compiling GCC from source, it can take anywhere
-between 30-60 minutes or more depending on your machine.
-
-And finally to build a Emacs.app with native compilation enabled, 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.
+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.
