+various approaches, such as based on coreboot or UEFI PEI.
 
 The [`linuxboot`](https://github.com/linuxboot/linuxboot) repository contains a

-## Why?
+## Benefits
 
-*   Improves boot reliability by replacing lightly-tested firmware drivers with
-    hardened Linux drivers.
-*   Improves boot time by removing unnecessary code. Typically makes boot 20
-    times faster.
-*   Allows customization of the initrd runtime to support site-specific needs
-    (both device drivers as well as custom executables).
-*   Proven approach for almost 20 years in military, consumer electronics, and
-    supercomputing systems -- wherever reliability and performance are
-    paramount.

+As a bootloader environment, it offers
 
-The official documentation for LinuxBoot is the [LinuxBoot Book](https://book.linuxboot.org),
-where you can find information on how LinuxBoot works, how to build the various
-flavours (e.g. coreboot/LinuxBoot or UEFI PEI/LinuxBoot), the
-[u-root](https://github.com/u-root/u-root) ramfs builder, etc.
+*   Steadfast reliability through bespoke and well-tested drivers
+*   Improved boot time by excluding unnecessary code, typically 20 times faster
+    than other solutions
+*   Runtime customization for support site-specific needs, covering both device
+    drivers as well as executables
