+Internals
+=========
+
+There are two main chroot jail used in JuNest.
+The main one is [proot](https://wiki.archlinux.org/index.php/Proot) which
+allows unprivileged users to execute programs inside a sandbox and
+[arch-chroot](https://wiki.archlinux.org/index.php/Chroot) which is an
+enhanced chroot for privileged users that mounts the primary directories
+(i.e. /proc, /sys, /dev and /run) before executing any programs inside
+the sandbox.
