-
-The **OpenAPI.NET** SDK contains a useful object model for OpenAPI documents in .NET along with common serializers to extract raw OpenAPI JSON and YAML documents from the model.
-
-**See more information on the OpenAPI specification and its history here: <a href="https://www.openapis.org">OpenAPI Initiative</a>**
-
-Project Objectives:
-
-- Provide a single shared object model in .NET for OpenAPI descriptions.
-- Include the most primitive Reader for ingesting OpenAPI JSON and YAML documents in both V2 and V3 formats.
-- Provide OpenAPI description writers for both V2 and V3 specification formats.
-- Enable developers to create Readers that translate different data formats into OpenAPI descriptions. 
-
-# Installation
-
-- Install core Nuget package [**Microsoft.OpenApi**](https://www.nuget.org/packages/Microsoft.OpenApi)
-- Install readers Nuget package [**Microsoft.OpenApi.Readers**](https://www.nuget.org/packages/Microsoft.OpenApi.Readers)
-
-> Note: version 2 of this library, which brings support for OpenAPI 3.1, is currently in preview. Due to early versioning issues with the preview, and package renaming, the installation must be done with a specific version number to get the latest version:
-> ```bash
-> # x-release-please-start-version
-> dotnet add package Microsoft.OpenAPI --version 2.0.0-preview.29
-> # x-release-please-end
-> # x-release-please-start-version
-> dotnet add package Microsoft.OpenAPI.YamlReader --version 2.0.0-preview.29
-> # x-release-please-end
-> ```
-> Until this new version is generally available, dependabot will periodically create pull requests which **downgrade** to preview 9, they should be ignored.
-> You can read more about the changes of this upcoming version [in the upgrade guide](./docs/upgrade-guide-2.md).

-# Processors
-The OpenAPI.NET project holds the base object model for representing OpenAPI documents as .NET objects. Some developers have found the need to write processors that convert other data formats into this OpenAPI.NET object model. We'd like to curate that list of processors in this section of the readme. 
-
-The base JSON and YAML processors are built into this project. Below is the list of the other supported processor projects.
-
-- [**C# Comment / Annotation Processor**](https://github.com/Microsoft/OpenAPI.NET.CSharpAnnotations) : Converts standard .NET annotations ( /// comments ) emitted from your build (MSBuild.exe) into OpenAPI.NET document object. 
-
-- [**OData CSDL Processor**](https://github.com/Microsoft/OpenAPI.NET.OData) : Converts the XML representation of the Entity Data Model (EDM) describing an OData Service into OpenAPI.NET document object. 
-
-# Example Usage
-
-Creating an OpenAPI Document
-
-```C#
-var document = new OpenApiDocument
-{
-    Info = new OpenApiInfo
-    {
-        Version = "1.0.0",
-        Title = "Swagger Petstore (Simple)",
-    },
-    Servers = new List<OpenApiServer>
-    {
-        new OpenApiServer { Url = "http://petstore.swagger.io/api" }
-    },
-    Paths = new OpenApiPaths
-    {
-        ["/pets"] = new OpenApiPathItem
-        {
-            Operations = new()
-            {
-                [HttpMethod.Get] = new OpenApiOperation
-                {
-                    Description = "Returns all pets from the system that the user has access to",
-                    Responses = new OpenApiResponses
-                    {
-                        ["200"] = new OpenApiResponse
-                        {
-                            Description = "OK"
-                        }
-                    }
-                }
-            }
-        }
-    }
-};
-```
-
-Reading and writing an OpenAPI description
-
-```C#
-var httpClient = new HttpClient
-{
-    BaseAddress = new Uri("https://raw.githubusercontent.com/OAI/OpenAPI-Specification/")
-};
-
-var stream = await httpClient.GetStreamAsync("main/examples/v3.0/petstore.yaml");
-
-// Read V3 as YAML
-var openApiDocument = new OpenApiStreamReader().Read(stream, out var diagnostic);
-
-// Write V2 as JSON
-var outputString = openApiDocument.Serialize(OpenApiSpecVersion.OpenApi2_0, OpenApiConstants.Json);
-
-```
-
-# Validating/Testing OpenAPI descriptions
-In order to test the validity of an OpenApi document, we avail the following tools:
-- [Microsoft.OpenApi.Hidi](https://www.nuget.org/packages/Microsoft.OpenApi.Hidi)
-
-    A commandline tool for validating and transforming OpenAPI descriptions. [Installation guidelines and documentation](https://github.com/microsoft/OpenAPI.NET/blob/main/src/Microsoft.OpenApi.Hidi/readme.md)
-
-- Microsoft.OpenApi.Workbench
-
-    A workbench tool consisting of a GUI where you can test and convert OpenAPI descriptions in both JSON and YAML from v2-->v3 and vice versa.
-
-    #### Installation guidelines:
-    1. Clone the repo locally by running this command:
-        `git clone https://github.com/microsoft/OpenAPI.NET.git`
-    2. Open the solution file `(.sln)` in the root of the project with Visual Studio
-    3. Navigate to the `src/Microsoft.OpenApi.Workbench` directory and set it as the startup project
-    4. Run the project and you'll see a GUI pop up resembling the one below:
-    
-    
-    ![workbench preview](https://raw.githubusercontent.com/microsoft/OpenAPI.NET/main/docs/images/workbench.png "a screenshot of the workbench application")
-    
-    5. Copy and paste your OpenAPI descriptions in the **Input Content** window or paste the path to the descriptions file in the **Input File** textbox and click on `Convert` to render the results.
