the "manusmriti" predominantly discusses the code of conduct (dharma rules) for the brahmins (priestly class) and the kshatriyas (king, administration and warrior class). the text mentions shudras, as well as vaishyas, but this part is its shortest section. sections 9.326 – 9.335 of the "manusmriti" state eight rules for vaishyas and two for shudras.
