 # How to run
 Simply run the Web Api project from Visual Studio, or from a terminal by executing `dotnet run --project .\AspNetCore.Examples.Auth.Api\AspNetCore.Examples.Auth.Api.csproj` in the root folder.
 
+## Call the endpoints via SwaggerUI
 Access the web api at http://localhost:5297/swagger and try to call the endpoints:
 
 - Access `/auth/anonymous` to call an endpoint that requires no authentication.
 - The rest of the endpoints should return `401 Unauthorized`.
 - Click the `Authorize` button to authenticate with Duende Identity Server. Use any of the suggested users in the login page (`alice/alice` or `bob/bob` at the time of writing).
     - Call the `/auth/claims` endpoint to check your claims.
-    - Call the `/auth/only-admin` endpoint to use [Role Based Authorization](https://learn.microsoft.com/aspnet/core/security/authorization/roles?view=aspnetcore-8.0).
-    - Call the `/auth/only-alice` or `/auth/only-bob` endpoints to use [Claims Based Authorization](https://learn.microsoft.com/aspnet/core/security/authorization/claims?view=aspnetcore-8.0).
-    - Call the `/auth/only-recent-login` endpoint to use [Policy Based Authorization](https://learn.microsoft.com/aspnet/core/security/authorization/policies?view=aspnetcore-8.0).
-    - Call the `/auth/only-same-author` endpoint with the authenticated user email (check in the `/auth/claims` endpoint) to use [Resource Based Authorization](https://learn.microsoft.com/aspnet/core/security/authorization/resourcebased?view=aspnetcore-8.0).
+    - Call the `/auth/only-admin` endpoint to use [Role Based Authorization](https://learn.microsoft.com/aspnet/core/security/authorization/roles?view=aspnetcore-9.0).
+    - Call the `/auth/only-alice` or `/auth/only-bob` endpoints to use [Claims Based Authorization](https://learn.microsoft.com/aspnet/core/security/authorization/claims?view=aspnetcore-9.0).
+    - Call the `/auth/only-recent-login` endpoint to use [Policy Based Authorization](https://learn.microsoft.com/aspnet/core/security/authorization/policies?view=aspnetcore-9.0).
+    - Call the `/auth/only-same-author` endpoint with the authenticated user email (check in the `/auth/claims` endpoint) to use [Resource Based Authorization](https://learn.microsoft.com/aspnet/core/security/authorization/resourcebased?view=aspnetcore-9.0).
     - Any of these calls should return `403 Forbidden` if the requirements are not met.
 
+## Call the endpoints via ScalaR
+Access the web api at http://localhost:5297/scalar/v1 and try to call the endpoints:
+
+- Access `/auth/anonymous` to call an endpoint that requires no authentication.
+- The rest of the endpoints should return `401 Unauthorized`.
+- At the time of writing ScalaR does not fully support OAuth 2.0, so the rest of the endpoints will not be accessible. See https://github.com/scalar/scalar/issues/604
