[Source code] This repository contains the source code that is used to build the software packages from some of the other repositories. The \checkbox{Source code} option should not be selected unless you have experience with building applications from source. \marginnote{Building applications from source is an advanced process for creating packages, and usually only concerns developers. You may also require source files when using a custom \gls{kernel}, or if trying to use the latest version of an application before it is released for Ubuntu. As this is a more advanced area, it will not be covered in this manual.}
