+# CommunityToolkit.Hosting.Golang
+
+## Overview
+
+This is a .NET Aspire Integration for [Go](https://go.dev/) applications.
+
+## Usage
+
+```csharp
+var builder = DistributedApplication.CreateBuilder(args);
+
+var golang = builder.AddGolangApp("golang", "../gin-api");
+
+builder.Build().Run();
+```
+
+### Configuration
+- `name`- The name of the resource.
+- `workingDirectory`- The working directory to use for the command. If null, the working directory of the current process is used.
+- `port`- This is the port that will be given to other resource to communicate with this resource. Deafults to `8080`.
+- `args`- The optinal arguments to be passed to the executable when it is started.
+
+### OpenTelemetry Configuration
+
+In the [example](../../examples/golang/) folder, you can find an example of how to configure OpenTelemetry in the Go application to use the Aspire dashboard.
