 #### Chroot installation
 
-It is also possible to perform a chroot installation, which can require the
-`qemu-user-static` package together with either the `binfmt-support` or `proot`
-package if a computer with an incompatible architecture (such as i686) is being
-used. This guide explains how to use the `qemu-<platform>-static` program from
-`qemu-user-static` with [proot(1)](https://man.voidlinux.org/proot.1).

-First, [prepare your storage medium](#custom-partition-layout). Then, follow
