<h2><a href="#grapheneos">GrapheneOS</a></h2>
<p>The operating system source tree includes hundreds of repositories. Many of these
are only used for debugging, testing or development and are not actually part of what
gets used for building a production release. The manifest repository references all of
these. Most of these are used unmodified from the Android Open Source Project (AOSP).
A few dozen of the repositories including most of the core OS are either forked from
AOSP or are unique to GrapheneOS.</p>
<p>The operating system has a unified build system, but some components like
Chromium are too complex to fit into it so they're included as prebuilts instead
of porting them to the AOSP build system. This is also done for developer
convenience and bootstrapping, to avoid needing to build all the native /
cross-compilation toolchains for each host and target platform combination, etc.
The prebuilts can all be built from source if desired. The build instructions will
be expanded to cover all of this in the future.</p>
<p>For a full list of the repositories in the OS source tree, look at the
<a href="https://github.com/GrapheneOS/platform_manifest/blob/11/default.xml">default.xml
