<p>GrapheneOS is an <a href="https://opensource.org/osd">open source</a> project with
an open development process.</p>
<p>The GrapheneOS sources are hosted in the
<a href="https://github.com/GrapheneOS">GrapheneOS organization on GitHub</a>. Since
there are many repositories, this page aims to provide a guide for it. See the
<a href="/contact#reporting-issues">reporting issues section on the contact page</a>
for an comparable overview of where issues should be filed.</p>

<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/13/default.xml">default.xml
list in the manifest repository</a>.</p>

<p>An archive of legacy repositories is available via the
<a href="https://github.com/GrapheneOS-Archive">GrapheneOS Archive</a>
organization. This only covers repositories archives after renaming the project to
GrapheneOS. Earlier code is mostly not available via GitHub anymore due to
<a href="/history/#history">the unfortunate events</a> leading to the rename of
the project.</p>
