+You can extend Roast with project-specific configuration by creating initializers. These are automatically loaded when workflows run, allowing you to:
 
 - Add custom instrumentation
 - Configure monitoring and metrics
 - Set up project-specific tools
 - Customize workflow behavior
 
-Example structure:
+Roast supports initializers in multiple locations (in priority order):
+
+1. **Workflow-local initializers**: Place alongside your workflow steps
+2. **Global XDG config**: Shared across all projects using XDG Base Directory specification
+
+Example structures:
 ```

-  ├── .roast/

-  │       ├── metrics.rb
-  │       ├── logging.rb

+**XDG Configuration Directories:**
+- Config: `$XDG_CONFIG_HOME/roast` (default: `~/.config/roast`)
+- Cache: `$XDG_CACHE_HOME/roast` (default: `~/.cache/roast`)
+
+You can customize these locations by setting XDG environment variables:
