 - **xStringService**
 
+## Providers
+
+in this module all requirements tools for manage Terms and Conditions Integrated and Provided.
+
+- **IXTermsAndComditionsProvider**: an Interface for Describe Provided Actions for Terms and Conditions Management.
+- **XTermsAndComditionsProvider**: an Implementation of Provided Actions for Terms and Conditions Management.
+- **XTermsHub**: a Hub Implementation for Notifing Terms Changes to Connected Clients.
+- **IXTermsAndComditionsController**: an Interface for Describe base Terms and Conditions Management Controller Actions.
+- **XTermsAndComditionsControllerBase**: an Abstract Base Implementation of base Terms and Conditions Management Controller Actions.
+
+## Implementation
+
+you have to follow these steps for using this Module.
+
+### Configure Service
+
+all of Requirements for Terms and Conditions must be Configured using appSettings and provided by IConfiguration to Modules.
+
+fo using Service you Have to Configure the Service in you appSettings.json file.
+
+this configurations mapped to **XTermsAndConditionsServiceConfiguration** class.
+
+```C#
+/// <summary>
+/// Terms and Conditions Configuration ...
+/// </summary>
+public class XTermsAndConditionsServiceConfiguration
+{
+    /// <summary>
+    /// Terms And Conditions Resource Title in XString Table ...
+    /// </summary>
+    public string ResourceTitle { get; set; } = "terms_and_conditions";
+
+    /// <summary>
+    /// Seeding Mode for Terms and Conditions ...
+    /// </summary>
+    public XDbSeedingMode SeedingMode { get; set; } = XDbSeedingMode.AddIfNotExists;
+
+    /// <summary>
+    /// Default Terms and Conditions for Add to Databse on App Startup ...
+    /// </summary>
+    public List<XStringDto> TermsAndConditions { get; set; } = null;        
+}
+```
+
+a sample Configuration must like this:
+
+```json
+{
+    ...
+    "TermsAndConditionsService": {
+        "ResourceTitle": "terms_and_conditions",
+        "SeedingMode": "AddIfNotExists",
+        "TermsAndConditions": [
+        {
+            "Language": "fa-IR",
+            "TranslatedValue": "شرایط و ضوابط ثبت نام در سامانه"
+        }
+        ]
+    },
+    ...
+}
+```
+
+### Register Service
+
+after preparation of all requirements, final steps is Register Service.
+
+there are two main step:
+
+- **DI Registration**: in this phase, all Provided Services Registered in DI.
+- **Middleware Usage**: in this phase, if any Terms and Conditions Provided in Configuration, Seeded in Data Persist System using Provided Services.
+
+```C#
+public class Startup
+{
+    //
+    public void ConfigureServices(IServiceCollection services)
+    {
+        ...
+        //
+        // Register Terms and Conditions Service ...
+        services.AddXTermsConditionsService(
+            lifeTime: lifeTime,
+            configuration: configuration
+        );
+        ...
+    }
+
+    //
+    public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
+    {
+        ...
+        //
+        // Using Terms and Conditions Service ...
+        app.UseXTermsAndConditionsService();        
+        ...
+    }
+}
