+NetworkManager live VM scripts
+------------------------------
+
+This set of scripts can be used to build a live initramfs image suitable for
+testing NetworkManager in a virtual environment. The scripts themselves are
+intended to be used by a power user who can adapt them to their needs. The
+result, on the contrary, is intended to be used by anyone who wants to play
+with NetworkManager on the command line.
+
+Building the initramfs image:
+
+sudo ./build.sh [-n name] [-b branch/commit]
+
+You may have to update ./build.sh to suit your distribution. The included
+version is prepared for Fedora 20 and the image is also build using Fedora 20
+repositories.
+
+Then you can distribute the self-extracting archive and run it on other machines:
+
+./nm-live-vm-bundle.sh
