-# Building Chromium on Arch Linux
+# Building Chrome on Arch Linux

The docs sometimes call the browser "Chrome" and sometimes call it "Chromium".
The C++ style guide says to refer to the project as Chromium and the product as
Chrome:

https://chromium.googlesource.com/chromium/src/+/master/styleguide/c++/c++.md

I didn't aggressively try to standardize here (only changed a couple of major
headers), but maybe it's worth doing?

In this case I actually think of it more as talking about the project, not the
single binary. So I think Chromium is more appropriate, and I'd undo your
changes here.

SGTM, done.

 
 Generally speaking, follow the [Linux Build Instructions](linux_build_instructions.md).
 However, do the following instead to install the build dependencies:
 
-## Install the build dependencies:
+## Install the build dependencies
 
 Most of these packages are probably already installed since they're often used,
-and the parameter --needed ensures that packages up to date are not reinstalled.
+and the `--needed` parameter ensures that up-to-date packages are not
+reinstalled.
 
-    sudo pacman -S --needed python perl gcc gcc-libs bison flex gperf pkgconfig \
-    nss alsa-lib gconf glib2 gtk2 nspr ttf-ms-fonts freetype2 cairo dbus \
-    libgnome-keyring
+```shell
+$ sudo pacman -S --needed python perl gcc gcc-libs bison flex gperf pkgconfig \
+nss alsa-lib gconf glib2 gtk2 nspr ttf-ms-fonts freetype2 cairo dbus \
+libgnome-keyring
+```
 
 For the optional packages on Arch Linux:
 
-*   php-cgi is provided with pacman
-*   wdiff is not in the main repository but dwdiff is. You can get wdiff in
-    AUR/yaourt
-*   sun-java6-fonts do not seem to be in main repository or AUR.
+*   `php-cgi` is provided with `pacman`
