+# Pi Documentation
+
+Pi is a minimal terminal coding harness. It is designed to stay small at the core while being extended through TypeScript extensions, skills, prompt templates, themes, and pi packages.
+
+## Quick start
+
+Install pi with npm:
+
+```bash
+npm install -g @mariozechner/pi-coding-agent
+```
+
+And run it:
+
+```bash
+pi
+```
+
+Authenticate with `/login` for subscription providers, or set an API key such as `ANTHROPIC_API_KEY` before starting pi.
+
+## Start here
+
+- [Providers](providers.md) - subscription and API-key setup for built-in providers.
+- [Settings](settings.md) - global and project settings.
+- [Keybindings](keybindings.md) - default shortcuts and custom keybindings.
+- [Sessions](session.md) - session storage format and session files.
+- [Session tree](tree.md) - branching and navigating previous turns.
+- [Compaction](compaction.md) - context compaction and branch summarization.
+
+## Customization
+
+- [Extensions](extensions.md) - TypeScript modules for tools, commands, events, and custom UI.
+- [Skills](skills.md) - Agent Skills for reusable on-demand capabilities.
+- [Prompt templates](prompt-templates.md) - reusable prompts that expand from slash commands.
+- [Themes](themes.md) - built-in and custom terminal themes.
+- [Pi packages](packages.md) - bundle and share extensions, skills, prompts, and themes.
+- [Custom models](models.md) - add model entries for supported provider APIs.
+- [Custom providers](custom-provider.md) - implement custom APIs and OAuth flows.
+
+## Programmatic usage
+
+- [SDK](sdk.md) - embed pi in Node.js applications.
+- [RPC mode](rpc.md) - integrate over stdin/stdout JSONL.
+- [JSON event stream mode](json.md) - print mode with structured events.
+- [TUI components](tui.md) - build custom terminal UI for extensions.
+
+## Platform setup
+
+- [Windows](windows.md)
+- [Termux on Android](termux.md)
+- [tmux](tmux.md)
+- [Terminal setup](terminal-setup.md)
+- [Shell aliases](shell-aliases.md)
+
+## Development
+
+- [Development](development.md) - local setup, project structure, and debugging.
