+# Integrated CI/CD Flow with Codegen
+
+This example demonstrates a complete CI/CD pipeline using Codegen's components, creating a seamless workflow from requirements to deployment.
+
+## Architecture
+
+```
+[Requirements] → [Planning] → [Development] → [Review] → [Testing] → [Deployment] → [Monitoring]
+```
+
+### Components
+
+1. **Requirements & Planning Hub** (Linear + AI)
+   - Captures and analyzes requirements from Linear
+   - Breaks down complex tasks into manageable subtasks
+   - Creates a development plan with dependencies
+
+2. **AI-Assisted Development** (Local Checkout + Ticket-to-PR)
+   - Checks out code locally for development
+   - Uses AI to generate code changes based on requirements
+   - Creates PRs with detailed documentation
+
+3. **Comprehensive Code Review** (PR Review + Deep Analysis)
+   - Reviews PRs with multiple perspectives (style, security, performance)
+   - Performs deep code analysis to validate changes
+   - Provides feedback via GitHub and Slack
+
+4. **Continuous Knowledge & Assistance** (Slack Integration)
+   - Provides context and assistance throughout the pipeline
+   - Answers questions about the codebase and development process
+   - Facilitates team communication and knowledge sharing
+
+## Setup
+
+1. Create a `.env` file with your credentials:
+
+```
+# Linear
+LINEAR_ACCESS_TOKEN="your_linear_access_token"
+LINEAR_SIGNING_SECRET="your_linear_signing_secret"
+LINEAR_TEAM_ID="e30439bb-1547-4d4e-9934-eb757c9beb46"  # Zeeeepa team ID
+
+# GitHub
+GITHUB_TOKEN="your_github_token"
+
+# Slack
+SLACK_SIGNING_SECRET="your_slack_signing_secret"
+SLACK_BOT_TOKEN="your_slack_bot_token"
+
+# AI Providers
+ANTHROPIC_API_KEY="your_anthropic_key"
+OPENAI_API_KEY="your_openai_key"
+```
+
+2. Deploy with Modal:
+
+```bash
+modal deploy app.py
+```
+
+3. Configure webhooks:
+   - Linear: Use the Modal URL + `/linear/events`
+   - GitHub: Use the Modal URL + `/github/events`
+   - Slack: Use the Modal URL + `/slack/events`
+
+## Usage
+
+1. Create a Linear issue with the "Codegen" label
+2. The system will automatically:
+   - Analyze the issue and create a development plan
+   - Generate code changes based on the requirements
+   - Create a GitHub PR with the changes
+   - Review the PR and provide feedback
+   - Post updates to Slack
+
+## Components
+
+- `app.py`: Main application with Modal deployment
+- `models.py`: Shared data models
+- `events.py`: Event handlers for Linear, GitHub, and Slack
+- `agents.py`: AI agents for code generation and review
+- `utils.py`: Utility functions
