        ## For Local Development:
        
        ### Windows (Command Prompt):
        ```cmd
        set CLAUDE_API_KEY=your-claude-api-key-here
        set SAMBANOVA_API_KEY=your-sambanova-api-key-here
        set LM_STUDIO_URL=http://localhost:1234/v1
        set OLLAMA_URL=http://localhost:11434
        ```
        
        ### Windows (PowerShell):
        ```powershell
        $env:CLAUDE_API_KEY="your-claude-api-key-here"
        $env:SAMBANOVA_API_KEY="your-sambanova-api-key-here"
        $env:LM_STUDIO_URL="http://localhost:1234/v1"
        $env:OLLAMA_URL="http://localhost:11434"
        ```
        
        ### macOS/Linux (Bash):
        ```bash
        export CLAUDE_API_KEY="your-claude-api-key-here"
        export SAMBANOVA_API_KEY="your-sambanova-api-key-here"
        export LM_STUDIO_URL="http://localhost:1234/v1"
        export OLLAMA_URL="http://localhost:11434"
        ```
        
        ### .env File (Recommended):
        Create a `.env` file in your project directory:
        ```
        CLAUDE_API_KEY=your-claude-api-key-here
        SAMBANOVA_API_KEY=your-sambanova-api-key-here
        LM_STUDIO_URL=http://localhost:1234/v1
        OLLAMA_URL=http://localhost:11434
        ```
        
        ## Security Best Practices:
        1. Never commit API keys to version control
        2. Use different keys for development and production
        3. Regularly rotate your API keys
        4. Monitor API usage for unusual activity
        5. Use least-privilege access principles
