+(TODO: provide the content of /grml/chroot/grml_cd through the package
+grml-live, in the meanwhile get the content from a current grml-ISO)
+
+The class concept
+-----------------
+
+grml-live uses FAI and its class based concept for adjusting configuration
+according to your needs. This gives you flexibility and strength without losing
+the simplicity in the build process.
+
+The main and base class provided by grml-live is named GRML. It's strongly
+recommended to **always** use the class GRML when building an ISO using
+grml-live as well as the architecture dependend class (being 'I386' for x86_32
+currently only). The following files and directories are relevant for class GRML
+by default:
+
+ /etc/grml/fai/config/scripts/GRML/
+ /etc/grml/fai/config/debconf/GRML
+ /etc/grml/fai/config/class/GRML.var
+ /etc/grml/fai/config/hooks/instsoft.GRML
+ /etc/grml/fai/config/package_config/GRML
+
+Take a look at the next section for information about the concept of those
+files/directories.
+
+If you want to use your own configuration, extend an existing configuration
+and/or add additional packages to your ISO just invent a new class. For example
+if you want to use your own class named "FOOBAR" just extend CLASSES="GRML" inside
+/etc/grml/grml-live.conf to CLASSES="GRML,FOOBAR" or invoke grml-live using
+the classes option: "grml-live -c GRML,FOOBAR ...".
+
+More details regarding the class concept can be found in the documentation of
+FAI (available at /usr/share/doc/fai-doc/).
