It describes using "a lot of/lots of" for large positive quantities, "much" for large uncountable quantities, and "many" for large countable quantities. It also discusses using "plenty of" to mean enough or more than needed. Small quantities are described using "little" for uncountable nouns and "few" for countable nouns.
