 For external official modules to be discoverable during install, ensure an entry for the external repo is added to external-official-modules.yaml.
 
 For community modules - this will be handled in a different way. This file is only for registration of modules under the bmad-code-org.

+## Post-Install Configuration Notes for Module Authors
+
+The installer can display setup guidance to users after a module's configuration is collected. This is handled by the `displayModulePostConfigNotes(moduleName)` method in `installers/lib/core/config-collector.js`.
+
+### When It Runs
+
+The method is called in two places:
+
+- After `collectModuleConfig()` completes (full interactive configuration)
+- After `collectModuleConfigQuick()` completes (quick mode with existing config)
+
+This ensures users see relevant setup instructions regardless of installation path.
+
+### Guards
+
+Output is suppressed when:
+
+- **Silent mode** (`this._silentConfig`) — non-interactive installations skip all output
+- **Feature disabled** — e.g., if the config value is `'none'`, no guidance is needed
+
+### Adding Support for a New Module
+
+To add post-config notes for your module, add a conditional block in `displayModulePostConfigNotes()`:
+
+```javascript
+async displayModulePostConfigNotes(moduleName) {
+  if (this._silentConfig) return;
+
+  // Existing: TEA module handler
+  if (moduleName !== 'tea') return;
+  // ...
+
+  // To add your module, replace the early return above with:
+  if (moduleName === 'your-module') {
+    const config = this.collectedConfig[moduleName];
+    if (!config || !config.your_config_key) return;
+
+    const value = config.your_config_key;
+    if (value === 'none') return;
+
+    const color = await prompts.getColor();
+    await prompts.log.message('');
+    await prompts.log.info(color.bold('Your Setup Instructions:'));
+    await prompts.log.message(color.dim('  Instructions based on selected value...'));
+  }
+}
+```
+
+### Key Details
+
+- Read config values from `this.collectedConfig[moduleName]`
+- Use `prompts.log.info()` for headers and `prompts.log.message()` for details
+- Use `color.bold()` and `color.dim()` for visual hierarchy
+- The config question that drives the output is defined in the module's `module.yaml`
+
+### Working Example: TEA Module
+
+The TEA module defines a `tea_browser_automation` config question with options: `auto`, `cli`, `mcp`, `none`. After configuration, the handler at lines 1207-1235 displays Playwright CLI install commands and/or MCP setup links based on the user's selection.
