To build Gluon, use the following commands after checking out the repository:

git submodule update --init                                  # Get other repositories used by Gluon
git clone git://github.com/freifunk-gluon/site-ffhl.git site # Get the Freifunk Lübeck site repository - or use your own!
make                                                         # Build Gluon

When calling make, the OpenWRT build environment is prepared/updated. To rebuilt the images only, just use:

make images

The built images can be found in the directory /images.
