+# Creating a chroot rootfs
+
+As root, create a directory that will contain the chroot, and install a base
+system in it via the `base-voidstrap` package. If network access is required,
+copy `/etc/resolv.conf` into the chroot; `/etc/hosts` may need to be copied as
+well.
+
+Several directories then need to be mounted as follows:
+
+```
+# mount -t proc none <chroot_dir>/proc
+# mount -t sysfs none <chroot_dir>/sys
+# mount --rbind /dev <chroot_dir>/dev
+# mount --rbind /run <chroot_dir>/run
+```
+
+Use [chroot(1)](https://man.voidlinux.org/chroot.1) to change to the new root,
+then run programs as usual. Once you've finished using it, unmount the chroot
+using [umount(8)](https://man.voidlinux.org/umount.8).
+
+## PRoot
+
+An alternative to the above is [proot(1)](https://man.voidlinux.org/proot.1), a
+user-space implementation of chroot, mount --bind, and binfmt_misc. By
+installing the `proot` package, unprivileged users can utilize a chroot
+environment.
