Yes It explains each Mitzvah and it’s laws but as a separate note there’s also a certain kind of mitzvah in the Torah called a CHOK which means a Mitzvah that has no meaning and is done only cause we were commanded by Hashem to do it. An example of such a Mitzvah is the Mitzvah of Para Aduma/the Red Cow to purify the unpure person.
