-OfX.Grpc is an extension package for OfX that uses gRPC to transport data.
+OfX.gRPC is an extension package for OfX that leverages gRPC for efficient data transportation. This package provides a high-performance, strongly-typed communication layer for OfX’s Attribute-based Data Mapping, enabling streamlined data retrieval across distributed systems.

 ## Introduction
 
-OfX.Grpc extends the core OfX library by providing seamless integration with Entity Framework Core. This enables developers to automatically map and retrieve data directly from a database, leveraging the power of EF Core along with attribute-based data mapping.
-
-For example, suppose you have a `UserId` property in your model, and you want to fetch the corresponding `UserName` and `Email` fields from the database. By using OfX.EntityFrameworkCore, you can annotate your model with attributes, and the library will handle data fetching for you.
+gRPC-based Transport: Implements gRPC to handle data communication between services, providing a fast, secure, and scalable solution.

 To install the OfX.EntityFrameworkCore package, use the following NuGet command:
 
 ```bash
-dotnet add package OfX-EFCore
+dotnet add package OfX-gRPC
 ```
 
 Or via the NuGet Package Manager:
 
 ```bash
-Install-Package OfX-EFCore
+Install-Package OfX-gRPC
 ```

 ## How to Use
 
-### 1. Register OfX.EntityFrameworkCore
+### 1. Register OfX-gRPC
+
+Add OfX-gRPC to your service configuration during application startup:
 
-Add OfX.EntityFrameworkCore to your service configuration during application startup:
+For Client:
 
 ```csharp
 builder.Services.AddOfXEntityFrameworkCore(cfg =>
 {
     cfg.RegisterContractsContainsAssemblies(typeof(SomeContractAssemblyMarker).Assembly);
     cfg.RegisterHandlersContainsAssembly<SomeHandlerAssemblyMarker>();
-})
-.AddOfXEFCore<ServiceDbContext>()
-.AddOfXHandlers<IHandlerAssemblyMarker>();
-```
-
-After installing the package OfX-EFCore, you can use the extension method `RegisterOfXEntityFramework()`, which takes two arguments: the `DbContext` and the handlers assembly.
+    cfg.RegisterClientsAsGrpc(config => config.RegisterForAssembly<SomeContractAssemblyMarker>("http://localhost:5001")); //gRPC server host
 
-### 2. Write a Handler Using EF Core
-
-Implement a request handler to fetch the required data using Entity Framework Core. For example:
-
-```csharp
-public sealed class UserOfXHandler(IServiceProvider serviceProvider)
-    : EfQueryOfXHandler<User, GetUserOfXQuery>(serviceProvider)
-{
-    protected override Func<GetUserOfXQuery, Expression<Func<User, bool>>> SetFilter() =>
-        q => u => q.SelectorIds.Contains(u.Id);
-
-    protected override Expression<Func<User, OfXDataResponse>> SetHowToGetDefaultData() =>
-        u => new OfXDataResponse { Id = u.Id, Value = u.Name };
-}
+});
 ```
 
-### Function Details
-
-#### `SetFilter`
-This function is used to define the filter for querying data. It takes the query (`GetUserOfXQuery`) as an argument and returns an `Expression<Func<TModel, bool>>`, where `TModel` is your EF Core entity.
+For Server:
 
-Example:
 ```csharp
-protected override Func<GetUserOfXQuery, Expression<Func<User, bool>>> SetFilter() =>
-    q => u => q.SelectorIds.Contains(u.Id);
+var builder = WebApplication.CreateBuilder(args);
+...
+var app = builder.Build();
+...
+app.MapOfXGrpcService();
+...
 ```
-Here, `SetFilter` ensures that only entities matching the provided `SelectorIds` in the query are retrieved.
 
-#### `SetHowToGetDefaultData`
-This function specifies how to map the retrieved entity to the default data format. It returns an `Expression<Func<TModel, OfXDataResponse>>`, where `TModel` is your EF Core entity and `OfXDataResponse` is the mapped data structure.
+After installing the package OfX-gRPC, you can use the extension method `RegisterClientsAsGrpc()` for client and `MapOfXGrpcService()` for server. Look up at `RegisterClientsAsGrpc` function, we have to defind the contract assembly with server host, on this example above, all the queries are inclued in `SomeContractAssemblyMarker` assembly.
 
-Example:
-```csharp
-protected override Expression<Func<User, OfXDataResponse>> SetHowToGetDefaultData() =>
-    u => new OfXDataResponse { Id = u.Id, Value = u.Name };
-```
-Here, `SetHowToGetDefaultData` maps the `Id` and `Name` of the `User` entity to the `OfXDataResponse` format.
-
-By overriding these functions, you can customize the filtering logic and data mapping behavior to suit your application's requirements.
