 # All about u-root
 
-u-root is an embeddable root file system intended to be placed in a flash
-device as part of the firmware image, along with a Linux kernel. All the u-root
-utilities, roughly corresponding to standard Unix utilities, are written in [Go,
-a modern, type-safe language with garbage collection and language-level support
-for concurrency and inter-process communication](./u-root-golang.md).
+The u-root project consists of a build tool and sources to generate a root file

 u-root blurs the line between script-based distros such as Perl Linux[^24] and
 binary-based distros such as BusyBox[^26]. It has the flexibility of Perl Linux
