@@ -10,13 +10,20 @@ When creating, modifying, or removing plugins:
    - Brief description of functionality
    - Usage instructions with examples
    - Any configuration requirements
+3. **For plugins with configuration options:**
+   - Set `ConfigRequired: true` in the plugin's BasePlugin struct
+   - Add corresponding HTML form fields in `internal/admin/templates/channel_plugin_config.html`
+   - Use conditional template logic: `{{else if eq .ChannelPlugin.PluginID "plugin.id"}}`
+   - Include proper form labels, help text, and value binding
 
 ## Testing
 
-Before committing plugin changes:
+**CRITICAL**: After making ANY changes to code files, you MUST run these commands in order:
 
-1. Check files are properly formatted: Run `make format`
-2. Check code style and linting: Run `make lint`
-3. Test the plugin functionality: Run `make test`
+1. **Format code**: `make format` - Format all code according to project standards
+2. **Lint code**: `make lint` - Check code style and quality (must show "0 issues")
+3. **Run tests**: `make test` - Run all tests to ensure functionality works
 4. Verify documentation accuracy
 5. Ensure all examples work as described
+
+**These commands are MANDATORY after every code change, no exceptions.**
