 ## Customization
 
+### Creating a New Application from Scratch
+
+To create a **completely new application** (not based on the Claude Clone example):
+
+1. **Read the guide**: See [GUIDE_NEW_APP.md](GUIDE_NEW_APP.md) for detailed instructions
+2. **Use the template**: Copy `prompts/app_spec_template.txt` as a starting point
+3. **Reference the example**: Use `prompts/app_spec.txt` (Claude Clone) as a reference for structure and detail level
+4. **Create your spec**: Write your `prompts/app_spec.txt` with your application specification
+5. **Launch**: Run `python autonomous_agent_demo.py --project-dir ./my_new_app`
+
+**Key points:**
+- Keep the framework files unchanged (they're generic and reusable)
+- Only create/modify `prompts/app_spec.txt` for your new application
+- Use the XML structure from the Claude Clone example as a template
+- Define features with `<feature_X>` tags - each will become a Linear issue
+
 ### Changing the Application
 
 Edit `prompts/app_spec.txt` to specify a different application to build.
