+== About Buildroot
+
+Buildroot is a tool that simplifies and automates the process of
+building a complete Linux system for an embedded system, using
+cross-compilation.
+
+In order to achieve this, Buildroot is able to generate a
+cross-compilation toolchain, a root filesystem, a Linux kernel image
+and a bootloader for your target. Buildroot can be used for any
+combination of these options, independently (you can for example use
+an existing cross-compilation toolchain, and build only your root
+filesystem with Buildroot).
+
+Buildroot is useful mainly for people working with embedded systems.
+Embedded systems often use processors that are not the regular x86
+processors everyone is used to having in his PC. They can be PowerPC
+processors, MIPS processors, ARM processors, etc.
+
+Buildroot supports numerous processors and their variants; it also
+comes with default configurations for several boards available
+off-the-shelf. Besides this, a number of third-party projects are based on,
+or develop their BSP footnote:[BSP: Board Support Package] or
+SDK footnote:[SDK: Software Development Kit] on top of Buildroot.
