A Software Requirements Specification (SRS) is a document that lays out the description of the software that is to be developed as well as the intention of the software under development. Software requirements specification shows what the software is supposed to do as well as how it is supposed to perform.

A software requirements specification (SRS) is a description of a software system to be developed. ... Used appropriately, software requirements specifications can help prevent software project failure. The software requirements specification document lists sufficient and necessary requirements for the project development.
