 ### 2. Database Setup
 
-The CMS shares a database with the Polaris/Arcturus emulator. Use an existing database or create a new one:
+The CMS supports both **MySQL / MariaDB** and **PostgreSQL**. The database type is automatically detected from your `DATABASE_URL` protocol (`mysql://` or `postgres://`).
 
+#### Option A: MySQL / MariaDB
+Create your database:
 ```sql
 CREATE DATABASE IF NOT EXISTS epicnext_cms CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
 ```
 
-The CMS reads emulator-owned tables (`users`, `items`, `rooms`, `bans`, etc.) directly. It never creates, alters, or drops them. The Drizzle schema in `src/db/schema.ts` is generated from the existing database structure and does not modify it.
+#### Option B: PostgreSQL
+Create your database:
+```sql
+CREATE DATABASE epicnext_cms;
+```
+
+The CMS reads emulator-owned tables (`users`, `items`, `rooms`, `bans`, etc.) directly. It never creates, alters, or drops them. The Drizzle schema in `src/db/schema.ts` maps to the existing database structure.
 
 > **Note:** The CMS does **not** own the emulator schema — it maps to those tables via Drizzle. Never run `drizzle-kit push` / `migrate` against the shared DB. CMS-owned tables (`website_*`, `radio_*`, etc.) are created via idempotent SQL in `drizzle/migrations/`.
