# Pi Documentation Overview Source: https://pi.dev/docs/latest Pi is a minimal terminal coding harness. The core stays small and most workflow-specific behavior lives in TypeScript extensions, skills, prompt templates, themes, and Pi packages. Positioning on `https://pi.dev/`: "There are many agent harnesses but this one is yours" — four run modes (interactive, print/JSON, RPC, SDK), 15+ providers with mid-session model switching, tree-structured shareable sessions, steering and follow-up during a run, and extensible primitives instead of baked-in features. ## Top-Level Areas - Start here: quickstart, usage, providers, llama.cpp, security, containerization, settings, keybindings, sessions, compaction. - Customization: extensions, skills, prompt templates, themes, Pi packages, custom models, custom providers. - Programmatic usage: SDK, RPC mode, JSON event stream mode, TUI components. - Reference: environment variables, session file format and SessionManager API. - Platform setup: Windows, Termux, tmux, terminal setup, shell aliases. - Development: local source setup, rebranding, debug logs, tests, package structure. ## Quick Install ```bash npm install -g --ignore-scripts @earendil-works/pi-coding-agent pi ``` On Linux/macOS the installer is also available: ```bash curl -fsSL https://pi.dev/install.sh | sh ``` pnpm and bun global installs work too (`pnpm add -g --ignore-scripts ...`, `bun add -g --ignore-scripts ...`). Authenticate with `/login` for subscription providers or set API keys such as `ANTHROPIC_API_KEY` before startup. ## Ecosystem Package gallery at `https://pi.dev/packages` lists community extensions tagged `pi-package`. Source: `https://github.com/earendil-works/pi` (formerly `pi-mono`; docs live under `packages/coding-agent/docs/`, and doc pages still link the old repo name, which redirects). Pi requires Node.js >= 22.19.0. The published version this skill was written against is `0.84.2` (`https://pi.dev/api/latest-version` reports the current one).
