Concepts
These are the various concepts that people may need to know while learning a technology tutorial and could be required to complete a ‘hookup’ tutorial. Concepts are most often a general building block that may be built upon other concepts. Concepts can generally be learned without physical objects but are reinforced with a hookup tutorial.
