## Description

pnpm is a command-line package manager designed to automate the retrieval, installation, and version management of software dependencies. It utilizes a deterministic resolution process and a lockfile to ensure that dependency trees remain consistent across different environments and machines.

The project distinguishes itself through a content-addressable storage engine that saves every version of a package exactly once on the file system. By employing a hard-linking installation strategy and a symlink-based directory structure, it maps dependencies from a central store into individual projects. This approach enforces strict dependency isolation, preventing code from accessing undeclared packages while simultaneously reducing disk usage and accelerating installation times through parallel execution.

Beyond its core installation capabilities, the tool provides built-in support for monorepo workspace orchestration, allowing for the management of multiple interconnected projects within a single repository. It maintains a virtual store layout to ensure a predictable dependency graph across complex project structures.
