To add additional document to the component use the *.compdoc file. This file is located in the model-folder. The component can be generally described with the 'Description' keyword followed by a colon and a string:

	Description : <text>
				

Furthermore information about licences, hardware requirements and the general purpose of the component can be added. To do so, the keywords 'Licence', 'HardwareRequirements' and 'Purpose' are used.

	Licence : <text>
	HardwareRequirements : <text>
	Purpose : <text>
				

The different states and services of the componend can also be described. A high level description of states can be added with the keyword 'State_neutral' or 'State_Mainstate'. Thereby the keyword 'State_neutral' is used to describe the neutral state and the keyword 'State_Mainstate' followed by the name of the state to describe a mainstate.

	State_neutral : <text>
	State_Mainstate <name> : <text>
				

Services are documented with the keyword 'Service' followed by the name of the service. The description and further information about their behavior in specific states are enclosed by curly braces:

	Service <name> {
		Description : <text>
		State_neutral : <text>
		State_Mainstate <name> : <text>
	}
				

From the textual parameter documentation, the information provided in the *.compdoc file and the component model a documentation is generated with doxygen.
