+### Prerequisites
+
+Stagehand requires a local browser installation. The library uses Playwright to manage browser instances automatically. No additional browser setup is required - Playwright will download the necessary browser binaries on first use.

+## Configuration Options
+
+### Basic Configuration
+
+```python
+# OpenAI (default)
+config = StagehandConfig(
+    model_name="gpt-4o-mini",
+    model_client_options={
+        "api_key": os.getenv("OPENAI_API_KEY")
+    }
+)
+
+# Anthropic Claude
+config = StagehandConfig(
+    model_name="claude-3-haiku-20240307",
+    model_client_options={
+        "api_base": "https://api.anthropic.com",
+        "api_key": os.getenv("ANTHROPIC_API_KEY")
+    }
+)
+```
+
+### Custom API Endpoints
+
+Stagehand supports various OpenAI/Anthropic compatible providers:
+
+```python
+# Together AI
+config = StagehandConfig(
+    model_name="meta-llama/Llama-2-7b-chat-hf",
+    model_client_options={
+        "api_base": "https://api.together.xyz/v1",
+        "api_key": os.getenv("TOGETHER_API_KEY")
+    }
+)
+
+# Groq
+config = StagehandConfig(
+    model_name="llama2-70b-4096",
+    model_client_options={
+        "api_base": "https://api.groq.com/openai/v1",
+        "api_key": os.getenv("GROQ_API_KEY")
+    }
+)
+
+# Local OpenAI-compatible server
+config = StagehandConfig(
+    model_name="local/custom-model",
+    model_client_options={
+        "api_base": "http://localhost:8000/v1",
+        "api_key": "local-key"
+    }
+)
+```
+
+### Browser Configuration
+
+```python
+config = StagehandConfig(
+    model_name="gpt-4o-mini",
+    model_client_options={"api_key": os.getenv("OPENAI_API_KEY")},
+    local_browser_launch_options={
+        "headless": True,  # Run in headless mode
+        "viewport": {"width": 1280, "height": 720},
+        "user_data_dir": "./browser_data",  # Persistent browser data
+        "args": ["--no-sandbox", "--disable-dev-shm-usage"]  # Additional Chrome args
+    }
+)
+```
+
+## Migration from Browserbase
+
+If you're upgrading from a previous version that used Browserbase, here's how to migrate your configuration:
+
+### Quick Migration Check
+
+Use our migration utility to scan your project:
+
+```bash
+# Scan current directory for files needing migration
+python docs/migration_utility.py scan .
+
+# Generate configuration examples
+python docs/migration_utility.py config openai
+```
+
+### Before (Browserbase Configuration)
+```python
+# Old Browserbase configuration
+config = StagehandConfig(
+    env="BROWSERBASE",
+    api_key="browserbase-api-key",
+    project_id="browserbase-project-id",
+    model_name="gpt-4o",
+    model_api_key="openai-api-key"
+)
+```
+
+### After (Local Configuration)
+```python
+# New local configuration
+config = StagehandConfig(
+    model_name="gpt-4o",
+    model_client_options={
+        "api_key": "openai-api-key",
+        # Optional: specify custom endpoint
+        "api_base": "https://api.openai.com/v1"
+    },
+    local_browser_launch_options={
+        "headless": False  # Configure browser options as needed
+    }
+)
+```
+
+### Key Changes
+- **Removed**: `env`, `api_key`, `project_id` parameters
+- **Replaced**: `model_api_key` with `model_client_options.api_key`
+- **Added**: `local_browser_launch_options` for browser configuration
+- **Enhanced**: Support for custom API endpoints via `model_client_options.api_base`
+
+### Environment Variables
+Update your environment variables:
+```bash
+# Remove these (no longer needed)
+# BROWSERBASE_API_KEY=your-browserbase-key
+# BROWSERBASE_PROJECT_ID=your-project-id
+
+# Keep or add these
+OPENAI_API_KEY=your-openai-key
+# Or for other providers:
+# ANTHROPIC_API_KEY=your-anthropic-key
+# TOGETHER_API_KEY=your-together-key
+```
+
+For a complete migration guide with troubleshooting, see [docs/migration_guide.md](docs/migration_guide.md).
