             support for your own builds.</p>

+            <h2>Device support</h2>
+            <p>In the current early stage of the project, GrapheneOS provides production releases
+            for the Pixel, Pixel XL, Pixel 2, Pixel 2 XL, Pixel 3 and Pixel 3 XL. It will support
+            other devices in the future, but devices are carefully chosen based on their merits
+            rather than the project aiming to have broad device support. Broad device support is
+            counter to the aims of the project, and the project will eventually be engaging in
+            hardware and firmware level improvements rather than only offering suggestions and bug
+            reports upstream for those areas. Much of the work on the project involves changes
+            that are specific to different devices, and officially supported devices are the ones
+            targeted by most of this ongoing work. GrapheneOS also has source level support
+            without device-specific hardening for the Android emulator, HiKey, HiKey 960 and also
+            generic targets providing basic support for many other devices.</p>
+            <p>Devices need to be meet the standards of the project in order to be considered as
+            potential targets. In addition to support for installing other operating systems,
+            standard hardware-based security features like the hardware-backed keystores, verified
+            boot and attestation need to be available. Devices with support for alternative
+            operating systems as an afterthought will not be considered. Devices need to have
+            proper ongoing support for their firmware and software specific to the hardware like
+            drivers in order to provide proper full security updates too. Devices that are
+            end-of-life and no longer receiving these updates will not be supported.</p>
+            <p>In order to support a device, the appropriate resources also need to be available
+            and dedicated towards it. Releases for each supported device need to be robust and
+            stable, with all standard functionality working properly and testing for each of the
+            releases.</p>
+            <p>Hardware, firmware and software specific to devices like drivers play a huge role
+            in the overall security of a device. The goal of the project is not to slightly
+            improve some aspects of insecure devices and supporting a broad set of devices would
+            be directly counter to the values of the project. A lot of the low-level work also
+            ends up being fairly tied to the hardware.</p>
