+# atomcms-next
+
+AtomCMS (Laravel) converted to **Next.js 16** (App Router) + **Prisma 7** against the
+same Arcturus-emulator MySQL/MariaDB database. Auth via NextAuth (argon2id/bcrypt +
+md5→argon2id upgrade), RCON to the emulator, full public site + admin panel.
+
+## Try it now (no database)
+
+The dev/preview server is already running — open:
+
+> **http://localhost:3000**
+
+Public pages render with fallback defaults (empty data). Login / register / admin
+need a database (below).
+
+## Try it for real (your AtomCMS database)
+
+Point it at your live (or a copy of your) AtomCMS database to log in with real
+accounts and see real data:
+
+1. Edit `atomcms-next/.env`:
+   ```dotenv
+   DATABASE_URL=mysql://USER:PASSWORD@HOST:3306/DBNAME
+   DATABASE_CONNECT_TIMEOUT_MS=10000
+   AUTH_SECRET=any-long-random-string-at-least-32-chars
+   HOTEL_NAME=YourHotel
+   # Optional emulator link (for RCON: give credits, ban, motto, disconnect):
+   RCON_HOST=127.0.0.1
+   RCON_PORT=3001
+   ```
+2. Restart the server (`pnpm -C atomcms-next start`, or `pnpm dev`).
+3. Log in at `/login` with any existing account. Staff (rank ≥ `min_staff_rank`,
+   default 7) get the **/admin** panel. New users can `/register`.
+
+It reads the schema you already have — no migrations are run against the emulator
+tables (introspect/conform only). `prisma generate` is already done; if you add
+tables, `pnpm -C atomcms-next prisma:generate`.
+
+## Run it yourself
+
+```bash
+cd atomcms-next
+pnpm install          # already done
+pnpm dev              # dev server (hot reload) on :3000
+# or:
+pnpm build && pnpm start   # production
+pnpm typecheck        # tsc --noEmit
+pnpm test             # vitest (unit tests)
+```
+

+  rare-values, photos, bans, applications, word-filter, IP, logs, teams,
+  housekeeping, permissions, emulator config, email templates, calendar,
+  subscriptions, CMS settings.
