 ## Dependencies
 
-Litterbox is a mostly static binary and only links to a few very standard shared libraries (that should exist on most Linux systems) as shown below:
-
-```bash
-gerhard@big-desktop:~$ ldd $(which litterbox)
-	linux-vdso.so.1 (0x00007bef700a4000)
-	libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007bef70060000)
-	libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007bef6eef3000)
-	libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007bef6ec00000)

+Litterbox is a mostly static binary and therefore does not depend on any system libraries. However,it depends on `podman` being installed on your system and the `mknod` command being available.
 
 Hence, almost any modern Linux distro on which you can install `podman` should work. In the future, the goal is to also take advantage of `Landlock` for added security on systems where it is available (i.e. most modern distros).
