+# Context7 - Live Library Documentation
+
+This document provides guidelines for using Context7 with Claude to get up-to-date, version-specific documentation for popular libraries.
+
+## Quick Setup
+
+```bash
+# One-time setup for Claude Code
+npx ctx7 setup --claude
+```
+
+This command:
+1. Authenticates via OAuth
+2. Generates an API key
+3. Installs the Context7 skill for Claude
+
+## Usage Examples
+
+Add `use context7` to your prompts to fetch live documentation:
+
+```
+How do I set up a NestJS application with TypeORM? use context7
+```
+
+```
+Show me the latest Prisma schema syntax for PostgreSQL. use context7
+```
+
+```
+What's the proper way to handle server-side rendering in SvelteKit? use context7
+```
+
+```
+How do I create a KafkaJS producer with SASL authentication? use context7
+```
+
+## Auto-Trigger Rules
+
+When working with the following libraries, Context7 should automatically provide live documentation:
+
+- **NestJS** - Backend framework for building efficient, scalable Node.js applications
+- **Prisma** - Next-generation ORM for Node.js and TypeScript
+- **SvelteKit** - Web development framework for building fast, modern apps
+- **KafkaJS** - Modern Apache Kafka client for Node.js
+- **BullMA** - Premium Node.js queue system based on Redis
+- **ioredis** - Robust, performance-focused Redis client for Node.js
+- **@solana/web3.js** - Solana JavaScript SDK for blockchain interactions
+
+## Best Practices
+
+### Specify Library ID
+
+For faster and more accurate results, include the library ID:
+
+```
+How do I configure Prisma relations? use library /prisma/docs for API and docs.
+```
+
+### Pin to a Version
+
+Get documentation for a specific version:
+
+```
+Show me NestJS 10.x middleware patterns. use context7
+```
+
+### When to Use Context7
+
+Always use Context7 when:
+- ✅ Writing code that uses external libraries/APIs
+- ✅ Looking for up-to-date code examples
+- ✅ Setting up or configuring packages
+- ✅ Debugging library-specific issues
+- ✅ Learning new framework features
+
+No need to specify when:
+- ❌ General programming questions
+- ❌ Algorithm or data structure discussions
+- ❌ Pure logic without external dependencies
+
+## Available MCP Tools
+
+When Context7 is set up, the following tools are available:
+
+- `resolve-library-id`: Find the correct library ID for a package
+- `query-docs`: Retrieve specific documentation for a library
