+Requirements for the build system
+---------------------------------
+
+* any Debian based system should be sufficient (if not please send a bug
+report), for example a grml2hd harddisk installation ships all you need
+
+* enough free disk space; at least 800MB are required for a minimal grml-live
+run (\~400MB for the chroot [$CHROOT_TARGET], \~150MB for the build target
+[$BUILD_TARGET] and \~150MB for the resulting ISO [$ISO_TARGET] plus some
+temporary files)
+
+* fast network access for retreiving the Debian packages used for creating the
+chroot (check out "local mirror" and "NFSROOT" to workaround this problem as far
+as possiblbe)
+
+Known TODOs
+-----------
+
+* document the available classes in more detail
+
+* make sure $TARGET is mounted rw,suid,dev
+
+* write a step-by-step guide **how** to adjust **what** at **which** place
+
+* add support for amd64 [gebi?] + ppc [formorer?] (and identify all packages
+that are arch specific so we have a clean package list in all classes)
+
+* support different grml-flavours through classes right out-of-the-box (being:
+grml, grml64, grml-small (done) for at least x86, amd64 and ppc)
+
+* support signed apt repositories (currently it's deactivated via FAI's
+FAI_ALLOW_UNSIGNED=1 for some packages in the toolchain)
+
+* explain (and provide configuration for) use of NFSROOT
+
+* support setting stuff like ISO name, version,... on-the-fly (especially for
+stuff inside boot/isolinux/*)
+
+* support "final builds" (including stuff like generating md5sums, gpg,... -
+create something like grml_release including all the details about the build
+like dpkg selection, logs,...)
+
+* the grml-live class(es) should send output as used inside FAI as well (so it's
+not as verbose unless you specify it, make it configurable)
+
+* provide possibility for cleanup of all created build directories and
+a smart summary of the buildprocess (including "took ... minutes/seconds to
+build...)
+
+* support hooks to allow further customisation of the build process
