+# MediaWiki
+
+MediaWiki is the wiki software that powers Wikipedia. It provides a full-featured collaborative wiki with a rich extension ecosystem.
+
+## Dependencies
+
+- **MySQL** - Database for storing wiki content
+- **SMTP** - For email notifications and password resets
+
+## Configuration
+
+Key settings in `config.yaml`:
+
+- **domain** - Where MediaWiki will be accessible
+- **storage** - Persistent volume size (default: `2Gi`)
+- **siteName** - Name of your wiki (default: `My Wiki`)
+- **adminUser** - Admin account username (default: `admin`)
+
+## First-Time Setup
+
+MediaWiki requires a **web-based installer** after deployment to generate `LocalSettings.php`.
+
+1. Add and deploy the app:
+   ```bash
+   wild app add mediawiki
+   wild app deploy mediawiki
+   ```
+
+2. Visit `/mw-config/` to run the web installer.
+
+3. In the installer:
+   - Database type: **MySQL**
+   - Database host: value of `db.host` from your config
+   - Database name: value of `db.name` (default: `mediawiki`)
+   - Database user/password: from your config and `secrets.yaml`
+   - Admin username/password: set to the values in your config and `secrets.yaml`
+
+4. At the end of the installer, download `LocalSettings.php` and copy it into the pod:
+   ```bash
+   kubectl cp LocalSettings.php mediawiki/<pod-name>:/var/www/html/LocalSettings.php
+   ```
+
+5. The wiki is now live.
+
+## Notes
+
+- The `secretKey` and `upgradeKey` are auto-generated in `secrets.yaml`
+- Extensions can be installed by copying them into the pod's `/var/www/html/extensions/` directory
+- The wiki will show a "maintenance mode" page until `LocalSettings.php` is in place
