+# راهنمای فارسی Swagger پروژه
+
+این پروژه حالا یک مستندات Swagger/OpenAPI داخلی دارد که از APIهای فعلی کد تولید شده است.
+
+## مسیرها
+
+- رابط Swagger UI: `/swagger`
+- خروجی خام OpenAPI JSON: `/api/openapi`
+
+## کاربرد هر مسیر
+
+- `/swagger` برای مشاهده، جستجو و تست Endpointها در مرورگر است.
+- `/api/openapi` برای اتصال ابزارهای دیگر مثل Postman Import، Redoc، یا CI/CD مناسب است.
+
+## نحوه استفاده
+
+1. پروژه را اجرا کنید.
+2. در مرورگر به `/swagger` بروید.
+3. از روی Tagها Endpoint مورد نظر را باز کنید.
+4. در صورت نیاز روی `Try it out` بزنید و ورودی را پر کنید.
+5. برای Endpointهای نیازمند احراز هویت، بهتر است ابتدا در همان مرورگر داخل برنامه لاگین کرده باشید.
+
+## احراز هویت
+
+این پروژه از `NextAuth` با Session Cookie استفاده می‌کند.
+
+- بیشتر APIهای کاربری با Session کار می‌کنند.
+- APIهای ادمین علاوه بر Session، نقش `ADMIN` هم می‌خواهند.
+- در Swagger نیازی به Bearer Token نیست، چون درخواست‌ها روی همان Origin اجرا می‌شوند و Cookie مرورگر قابل استفاده است.
+
+## دسته‌بندی Endpointها
+
+- `Auth`: ثبت‌نام، Session و مسیرهای پایه NextAuth
+- `User`: پروفایل و تست Session
+- `Team`: ساخت و مدیریت تیم فانتزی
+- `Players`: دریافت و مدیریت بازیکنان
+- `Countries`: دریافت و مدیریت کشورها
+- `Matches`: بازی‌ها، آمار، رویدادها و محاسبه امتیاز
+- `Rounds` و `Gameweeks`: مدیریت بازه‌های مسابقات
+- `Quiz`: کوئیز روزانه، نتایج و قرعه‌کشی
+- `Golden Cards`: کارت‌های طلایی
+- `Payment`: ساخت و تایید پرداخت
+- `Upload`: آپلود عکس بازیکن
+
+## نکات مهم
+
+- مسیر `/api/payment/verify` پاسخ JSON نمی‌دهد و کاربر را Redirect می‌کند.
+- مسیر `/api/upload/player-image` از `multipart/form-data` استفاده می‌کند.
+- برخی مسیرها مثل `POST /api/admin/matches/{id}/calc-points` از داده‌های ثبت‌شده قبلی استفاده می‌کنند و بدنه ورودی ندارند.
+- مستندات بر اساس Routeهای فعلی پروژه نوشته شده؛ اگر API جدید اضافه شود باید `lib/openapi.ts` هم به‌روزرسانی شود.
+
+## نگهداری مستندات
+
+فایل اصلی مستندات:
+
+- `lib/openapi.ts`
+
+Routeهای خروجی:
+
+- `app/api/openapi/route.ts`
+- `app/swagger/route.ts`
+
+اگر API جدیدی اضافه کردید:
+
+1. مسیر جدید را در `paths` اضافه کنید.
+2. در صورت نیاز Schema مشترک را در `components.schemas` تعریف کنید.
+3. اگر Endpoint نیازمند Session است، از Security فعلی استفاده کنید.
