+# Chroot demo
+
+This is a small script to create and setup a chroot
+
+To test edit the setup.sh script and change the BINARIES line to add the binaries you want.
+
+Then run `./setup.sh` it will create a `jail` directory next to the script.
+
+Finally run `sudo chroot jail` you should obtain a chrooted shell with only this executables
+
+## Warnings and limitation
+
+This is only a very small script for demonstrating what a chroot is.
+
+The script is not robust :
+
++ It only copies binaries no config files are shared files
++ Special directories are not mounted to the chroot, so no network, no devices etc.
++ lib64 is hardly coded, lib32 is not supported
++ I **do not** plan to maintain this script in any way
