LyX layout files for tuddesign.
I'm not the author, but as I couldn't find the origial source I thought it would be a good idea to back these up here on github.
You must have the tuddesign (classes and fonts) set up, see the above link.
Copy the layouts files from the layouts folder into your LyX layouts folder (e.g. in your user directory), then reconfigure LyX (Tools -> Reconfigure) and restart it. You should now be able to select the Document Class under Document -> Settings...
You can find example LyX files for all layouts in the examples folder.
This repository is no longer maintained. I started to work on LyX layouts files for the tuda-ci classes on https://github.com/Locke/lyx-tuda-ci
