-## What is Npgsql?
 
-Npgsql is the open source .NET data provider for PostgreSQL. It allows you to connect and interact with PostgreSQL server using .NET.
 
-For the full documentation, please visit [the Npgsql website](https://www.npgsql.org). For the Entity Framework Core provider that works with this provider, see [Npgsql.EntityFrameworkCore.PostgreSQL](https://github.com/npgsql/efcore.pg).
+## What is GaussDB ?
+
+GuassDB is an open-source database driver led by Huawei's open-source community and refactored based on npgsql. It is compatible with openGauss and Guass databases. [Open Source for Huawei](https://developer.huaweicloud.com/programs/opensource/contributing/) revolves around Huawei's technology ecosystems including Kunpeng, Ascend, HarmonyOS, and Huawei Cloud. Through collaboration with developers from enterprises, universities, and the open-source community, it enables adaptation development and solution validation for open-source software, ensuring smoother and more efficient operation on Huawei Cloud.  
+
+Before getting started, developers can download the [Open Source for Huawei Wiki](https://gitcode.com/HuaweiCloudDeveloper/OpenSourceForHuaweiWiki) to access detailed development procedures, technical preparations, and various resources required throughout the development process. If you have any questions during use, please visit the [GaussDB forum](https://bbs.huaweicloud.com/forum/forum-1350-1.html) for discussion.

 ## Quickstart
 
 Here's a basic code snippet to get you started:
 
 ```csharp
-using Npgsql;
+using GaussDB;
 
 var connString = "Host=myserver;Username=mylogin;Password=mypass;Database=mydatabase";
 
-var dataSourceBuilder = new NpgsqlDataSourceBuilder(connString);
+var dataSourceBuilder = new GaussDataSourceBuilder(connString);
 var dataSource = dataSourceBuilder.Build();
 
 var conn = await dataSource.OpenConnectionAsync();
 
 // Insert some data
-await using (var cmd = new NpgsqlCommand("INSERT INTO data (some_field) VALUES (@p)", conn))
+await using (var cmd = new GaussCommand("INSERT INTO data (some_field) VALUES (@p)", conn))
 {
     cmd.Parameters.AddWithValue("p", "Hello world");
     await cmd.ExecuteNonQueryAsync();
 }
 
 // Retrieve all rows
-await using (var cmd = new NpgsqlCommand("SELECT some_field FROM data", conn))
+await using (var cmd = new GaussCommand("SELECT some_field FROM data", conn))
 await using (var reader = await cmd.ExecuteReaderAsync())
 {
     while (await reader.ReadAsync())
         Console.WriteLine(reader.GetString(0));
 }
 ```
