The low level topic references information from the base
topic. In this case the name of the previously built image.
I think we should provide information on each low level
topic which references information from a base topic.
* Separate the high-level (building) from the low-level part (dumping)
* Introduce a subsection ("Working with Images"); not sure, if this is
useful under "Building Images"
* Enhance with some (general) advise about booting from USB
* Add abstract (use `.. sidebar`, not sure if we should use it)
* Collect all concept oriented text in the beginning
* Introduce procedure and create steps
* Remove lonely subsection and combine it with the procedure
TODO:
* Review
* Decide, if `.. sidebar` is ok (or should we better use `.. topic`?)
* Add additional, related information?
The current design of the documentation does not allow for
continous improvement and development. It's missing a basic
structure and concept for documenting step-by-step workflows
and generic explanations.
