-### Option 1. Install Open API Boilerplate Templates ###
-
-This is the easiest way to integrate the Open API document rendering. Run the following script based on your preference, which will install the pre-defined Open API document rendering endpoints.
-
-
-#### Download Installation Scripts ###
-
-Download the installation script using the PowerShell command.
-
-```powershell
-# PowerShell
-(Invoke-WebRequest `
-    -Uri "https://raw.githubusercontent.com/aliencube/AzureFunctions.Extensions/dev/scripts/Install-OpenApiHttpTriggerTemplates.ps1" `
-    -UseBasicParsing).Content | Out-File "<DIRECTORY>/Install-OpenApiHttpTriggerTemplates.ps1"
-```
-
-Alternatively, download the installation script using the Bash shell command. Make sure that the downloaded script MUST become executable.
-
-```bash
-# Bash
-curl -X GET "https://raw.githubusercontent.com/aliencube/AzureFunctions.Extensions/dev/scripts/Install-OpenApiHttpTriggerTemplates.sh" \
-    > "<DIRECTORY>/Install-OpenApiHttpTriggerTemplates.sh"
-
-chmod +x <DIRECTORY>/Install-OpenApiHttpTriggerTemplates.sh
-```
-
-> **NOTE**: Bash command does not support Azure Functions V1.
-
-
-#### Install Open API Boilerplate Templates ####
-
-Run the following script to install the Open API boilerplate templates in PowerShell.
-
-```powershell
-# PowerShell
-<DIRECTORY>/Install-OpenApiHttpTriggerTemplates.ps1 `
-    -ProjectPath <PROJECT> ` # Optional parameter. If omitted, it is set to the current directory.
-    -Namespace <NAMESPACE> ` # Optional parameter. If omitted, it is set to Aliencube.AzureFunctions.Extensions.OpenApi
-    -IsVersion1              # Optional switch only for Azure Functions v1.
-```
-
-Alternatively, run the following script to install the Open API boilerplate templates in Bash shell.
-
-```bash
-# Bash script
-<DIRECTORY>/Install-OpenApiHttpTriggerTemplates.sh \
-    <PROJECT> \ # Optional argument. If omitted, it is set to the current directory.
-    <NAMESPACE> # Optional argument. If omitted, it is set to Aliencube.AzureFunctions.Extensions.OpenApi
-```
-
-> **NOTE**: Bash script does not support Azure Functions V1.
-
-
-### Option 2. Write Open API Boilerplate Codes Manually ###
-
-Instead of installing the boilerplate code above, you can write the Open API boilerplate codes all by yourself.
-
-
-#### Open API Document Endpoint - `swagger.json` ####
-
-In order to render the `swagger.json` document, define the HTTP endpoint for it.
-
-```csharp
-[FunctionName(nameof(RenderSwaggerDocument))]
-[OpenApiIgnore]
-public static async Task<IActionResult> RenderSwaggerDocument(
-    [HttpTrigger(AuthorizationLevel.Function, "get", Route = "swagger.json")] HttpRequest req,
-    ILogger log)
-{
-    var openApiInfo = OpenApiInfoResolver.Resolve();
-    var host = HostJsonResolver.Resolve();
-    var httpSettings = host.GetHttpSettings();
-
-    var filter = new RouteConstraintFilter();
-    var helper = new DocumentHelper(filter);
-    var document = new Document(helper);
-    var result = await document.InitialiseDocument()
-                               .AddMetadata(openApiInfo)
-                               .AddServer(req, httpSettings.RoutePrefix)
-                               .Build(Assembly.GetExecutingAssembly(), new CamelCaseNamingStrategy())
-                               // Depending on what you pass, the rendered document can comply Open API v2 or v3, or JSON or YAML.
-                               .RenderAsync(OpenApiSpecVersion.OpenApi2_0, OpenApiFormat.Json)
-                               .ConfigureAwait(false);
-
-    var response = new ContentResult()
-                       {
-                           Content = result,
-                           ContentType = "application/json",
-                           StatusCode = (int)HttpStatusCode.OK
-                       };
-
-    return response;
-}
-```
-
-> **NOTE**: In order to render payload definitions in `camelCasing`, add `new CamelCaseNamingStrategy()` as an optional argument to the `Build()` method. If this is omitted, payload will be rendered as defined in the payload definitions.
-
-
-#### Swagger UI Page Endpoint ####
-
-In order to render the Swagger UI page, define the HTTP endpoint for it.
-
-```csharp
-[FunctionName(nameof(RenderSwaggerUI))]
-[OpenApiIgnore]
-public static async Task<IActionResult> RenderSwaggerUI(
-    [HttpTrigger(AuthorizationLevel.Function, "get", Route = "swagger/ui")] HttpRequest req,
-    ILogger log)
-{
-    var openApiInfo = OpenApiInfoResolver.Resolve();
-    var host = HostJsonResolver.Resolve();
-    var httpSettings = host.GetHttpSettings();
-    var swaggerAuthKey = Environment.GetEnvironmentVariable("OpenApi__ApiKey");
-
-    var ui = new SwaggerUI();
-    var result = await ui.AddMetadata(openApiInfo)
-                         .AddServer(req, httpSettings.RoutePrefix)
-                         .BuildAsync()
-                         .RenderAsync("swagger.json", swaggerAuthKey)
-                         .ConfigureAwait(false);
-    var response = new ContentResult()
-                       {
-                           Content = result,
-                           ContentType = "text/html",
-                           StatusCode = (int)HttpStatusCode.OK
-                       };
-
-    return response;
-}

 ### Expose Endpoints to Open API Document ###
 
 In order to include HTTP endpoints into the Open API document, use attribute classes (decorators) like:
