+# GreenHome.Sms.Ippanel
+
+سرویس ارسال پیامک IPPanel برای پروژه GreenHome
+
+## نصب و راه‌اندازی
+
+### 1. اضافه کردن Reference به پروژه
+
+در فایل `.csproj` پروژه خود:
+
+```xml
+<ItemGroup>
+  <ProjectReference Include="..\GreenHome.Sms.Ippanel\GreenHome.Sms.Ippanel.csproj" />
+</ItemGroup>
+```
+
+### 2. ثبت سرویس در Program.cs
+
+```csharp
+using GreenHome.Sms.Ippanel;
+
+// روش 1: استفاده از Configuration (پیشنهادی)
+builder.Services.AddIppanelSms(builder.Configuration);
+
+// روش 2: استفاده از Configuration Section
+builder.Services.AddIppanelSms(builder.Configuration.GetSection("IppanelSms"));
+
+// روش 3: تنظیم دستی
+builder.Services.AddIppanelSms(options =>
+{
+    options.BaseUrl = "https://edge.ippanel.com/v1";
+    options.AuthorizationToken = "YOUR_TOKEN_HERE";
+    options.DefaultSender = "10001001"; // اختیاری
+});
+```
+
+### 3. تنظیمات در appsettings.json
+
+```json
+{
+  "IppanelSms": {
+    "BaseUrl": "https://edge.ippanel.com/v1",
+    "AuthorizationToken": "YOUR_IPPANEL_TOKEN_HERE",
+    "DefaultSender": "10001001"
+  }
+}
+```
+
+## استفاده
+
+### تزریق سرویس
+
+```csharp
+public class MyController : ControllerBase
+{
+    private readonly ISmsService smsService;
+
+    public MyController(ISmsService smsService)
+    {
+        this.smsService = smsService;
+    }
+}
+```
+
+### ارسال Webservice SMS
+
+```csharp
+var request = new WebserviceSmsRequest
+{
+    Sender = "10001001",
+    Recipient = "09123456789", // یا چند شماره با کاما: "09123456789,09187654321"
+    Message = "سلام، این یک پیامک تست است"
+};
+
+var result = await smsService.SendWebserviceSmsAsync(request);
+// result.BulkId برای ردیابی پیامک استفاده می‌شود
+```
+
+### ارسال Pattern SMS
+
+```csharp
+var request = new PatternSmsRequest
+{
+    PatternCode = "your-pattern-code",
+    Recipient = "09123456789",
+    Variables = new Dictionary<string, string>
+    {
+        { "code", "12345" },
+        { "name", "کاربر" }
+    },
+    Originator = "10001001" // اختیاری، اگر نباشد از DefaultSender استفاده می‌شود
+};
+
+var result = await smsService.SendPatternSmsAsync(request);
+```
+
+## ساختار پروژه
+
+```
+GreenHome.Sms.Ippanel/
+├── IppanelSmsService.cs      # پیاده‌سازی سرویس
+├── IppanelSmsOptions.cs      # تنظیمات
+└── ServiceCollectionExtensions.cs  # Extension Methods برای ثبت سرویس
+```
+
+## نکات مهم
+
+1. **توکن IPPanel**: حتماً توکن معتبر خود را از پنل IPPanel دریافت و در تنظیمات قرار دهید
+2. **Webservice SMS**: می‌توانید چند گیرنده را با کاما جدا کنید
+3. **Pattern SMS**: معمولاً یک گیرنده در هر درخواست پشتیبانی می‌شود
+4. **خطاها**: تمام خطاها لاگ می‌شوند و به صورت Exception پرتاب می‌شوند
+
+## استفاده در پروژه‌های دیگر
+
+این پروژه مستقل است و می‌توانید آن را در هر پروژه .NET دیگری استفاده کنید:
+
+1. پروژه را به Solution خود اضافه کنید
+2. Reference را اضافه کنید
+3. `GreenHome.Application` را نیز Reference کنید (برای Interface و DTOs)
+4. سرویس را ثبت کنید
+
+## تغییر سرویس SMS
+
+اگر بخواهید از سرویس SMS دیگری استفاده کنید:
+
+1. یک پیاده‌سازی جدید از `ISmsService` ایجاد کنید
+2. در `Program.cs` به جای `AddIppanelSms` از متد ثبت سرویس جدید استفاده کنید
+
+Interface و DTOs در `GreenHome.Application` باقی می‌مانند و نیازی به تغییر کدهای استفاده‌کننده نیست.
