+Beyond Buildroot
+================
+
+Boot the generated images
+-------------------------
+
+NFS boot
+~~~~~~~~
+
+To achieve NFS-boot, enable _tar root filesystem_ in the _Filesystem
+images_ menu.
+
+After complete build, just run the following commands to setup the
+NFS-root directory:
+
+-------------------
+sudo tar -xavf /path/to/output_dir/rootfs.tar -C /path/to/nfs_root_dir
+-------------------
+
+Then, you can execute a NFS-boot from your target.
+
+Chroot
+------
+
+If you want to chroot in a generated image, then there are few thing
+you should be aware of:
+
+* you should setup the new root from the _tar root filesystem_ image;
+
+* either the selected target architecture is compatible with your host
+  machine, or you should use some +qemu-*+ binary and correctly set it
+  within the +binfmt+ properties to be able to run the binaries built
+  for the target on your host machine;
+
+* Buildroot does not currently provide +host-qemu+ and +binfmt+
+  correctly built and set for that kind of use.
