+What is Canoeboot?
+==================
+
+The *Canoeboot* project provides
+[free](https://writefreesoftware.org/learn) (*libre*) boot
+firmware based on coreboot, replacing proprietary BIOS/UEFI firmware
+on [specific Intel/AMD x86 and ARM based motherboards](docs/hardware/),
+including laptop and desktop computers. It initialises the hardware (e.g. memory
+controller, CPU, peripherals) and starts a bootloader for your operating
+system. [GNU+Linux](../docs/gnulinux/) and [BSD](../docs/bsd/) are well-supported. Help is
+available via [\#canoeboot](https://web.libera.chat/#canoeboot)
+on [Libera](https://libera.chat/) IRC.
+
+Canoeboot is a *special fork* of LIbreboot, maintained in parallel to it.
+Canoeboot adheres to the GNU Free System Distribution Guidelines, ensuring
+that everything in the flash is *free software*. Canoeboot *only* supports a
+very limited subset of hardware from coreboot (which it uses for initialisation)
+due to this policy, but it's provided for the purists who only want free
+software.
+The right to study, share, modify and use software freely without restrictions
+is a fundamental right that everyone *must* have.
+
+The benefit of Canoeboot is that it provides a completely
+automated build process and installation procedure, with well-tested builds
+released on a regular basis that the user can simply install, with minimal
+fuss. You can think of it as a *coreboot distro*. Coreboot provides snapshot
+source code archives every few months, but that's it. Canoeboot gives
+you the ROM images pre-compiled, with source code, and with payloads
+already pre-configured. In other words: Canoeboot makes coreboot
+extremely easy to use.
+
+More info about Canoeboot's design can be found in the [build system
+documentation](../docs/maintain/).

+Thoughts welcome!
