The document outlines the process of setting up a Swift package named 'swiftpm', including configuring dependencies and building the package using environment variables from the process info. It includes commands for resolving dependencies, building the package, and creating a static library from binary files. Additionally, it demonstrates initializing another package called 'swiftpm-modules' with a specific structure and dependencies.
