## README
# overlay-rpi4-openfyde
 
## Introduction
Same as Chromium OS, openFyde adopts the [Portage build and packaging system](https://wiki.gentoo.org/wiki/Portage) from Gentoo Linux. openFyde uses Portage with certain customisations to support building multiple targets (bootable OS system images) across different hardware architectures from a shared set of sources.
A **board** defines a target type, it can be either for a family of hardware devices or specifically for one type of device. For example, The board `amd64-openfyde` is a target type for an openFyde system image that aims to run on most recent PCs with amd64(x86_64) architecture; whilst the `rpi4-openfyde` board is a target type specifically for the infamous single-board computer [Raspberry Pi 4B](https://www.raspberrypi.com/products/raspberry-pi-4-model-b/). We usually append `-openfyde` to the board name in openFyde to differentiate between its siblings for FydeOS.
Each board has a corresponding **overlay** that defines the configuration for it. This includes details like CPU architecture, kernel configuration, as well as additional packages and USE flags.
