What do I need to create and use my LXDE CD/USB-pendrive?
1. Download the components of LXDE at Sourceforge
2. LXDE and LXQt Source Code
The components are available from a number of git repositories, mostly one per component to make it easier to pick and choose. Both LXDE and LXQt based components are living next to each other. Please check the path carefully.
git clone git clone git://git.lxde.org/git/ + project path.
