Customization
There are plenty of customization possibilities for a document. Have a look what options you can pass to the BFH classes or what variables are predefined for you.
In the section BFH Color aliases, you find a description how to change colors in your document. E.g., the background color of the title-page.
Furthermore, the BFH LaTeX developers provide some nice boxes and terminals. So you can highlight some important information in a document or create a self-explanatory tutorial with command line inputs. More information about these modules can be found in the section BFH Modules.
General customization, e.g. how to replace default headings and footers, are listed below.
