 ## [8.1.9]
 
+### Major Changes
+
+- Created a new project `Encamina.Enmarcha.Aspire` to handle configurations and extensions for Aspire.
+- Added `ResourceBuilderExtensions` class in `Encamina.Enmarcha.Aspire.Extensions`, which provides extension methods for configuring resources.
+  - The method `WithEnvironment<T>` was added to allow adding an array of environment variables to resources in a type-safe manner.
+
 ### Minor Changes
 
 - Added the `AuthenticationRequired` property to `SmtpClientOptions.cs`, which is set to `true` by default. This indicates that authentication is required to connect to the SMTP server. If set to `false`, the server does not require authentication, meaning no username or password is needed for the connection.
+- Added the `AtLeastOneRequiredAttribute` Data Annotation to validate that at least one of the specified properties has a value.
+- Enchanced `JsonUtils` with new methods: `FastCheckIsJson` and `IsAnAdaptiveCard`.
+- Added new `AtLeastOneRequiredSchemaFilter` to ensure OpenAPI schemas enforce that at least one of the specified properties is required, by modifying the schema to use the `anyOf` rule in Swagger documentation generation.

+[![Nuget package](https://img.shields.io/nuget/v/Encamina.Enmarcha.Aspire)](https://www.nuget.org/packages/Encamina.Enmarcha.Aspire)
+
+Aspire Resource Builder Extensions is a set of tools designed to simplify the configuration of cloud-native resources with environment variables. This package is ideal for projects that need to manage distributed application resources in a cloud environment using environment-specific configurations.
+
+## Setup
+
+### Nuget package
+
+First, [install NuGet](http://docs.nuget.org/docs/start-here/installing-nuget). Then, install [Encamina.Enmarcha.Aspire](https://www.nuget.org/packages/Encamina.Enmarcha.Aspire) from the package manager console:
+
+    PM> Install-Package Encamina.Enmarcha.Aspire
+
+### .NET CLI:
+
+[Install .NET CLI](https://learn.microsoft.com/en-us/dotnet/core/tools/). Next, install [Encamina.Enmarcha.Aspire](https://www.nuget.org/packages/Encamina.Enmarcha.Aspire) from the .NET CLI:
+
+    dotnet add package Encamina.Enmarcha.Aspire
+
+## How to use
+
+### Resource Builder Extensions
+
+The `ResourceBuilderExtensions` class provides a set of extension methods to configure Aspire resources.
+
+```csharp
+var agentProjects = builder.AddProject<Projects.AgentProjects>(appIdProjects)
+                           .WithEnvironment(Constants.Settings.Options.PendingTaskStatuses, pendingTaskStatuses)
