+# CommunityToolkit.Hosting.PapercutStmp
+
+## Overview
+
+This .NET Aspire Integration runs [Papercut SMTP](https://github.com/ChangemakerStudios/Papercut-SMTP) in a container.
+
+
+## Usage
+
+The Papercut SMTP integration exposes a connection string with the format `endpoint=smtp://:`.
+This connection string can be used to with a DbConnectionStringBuilder to get the smtp endpoint.
+
+### Example 1: Add Papercut SMTP with generated ports
+
+```csharp
+var builder = DistributedApplication.CreateBuilder(args);
+
+var papercut = builder.AddPapercutSmtp("papercut");
+
+var xyz = builder.AddProject("application")
+ .WithReference(papercut)
+ .WaitFor(papercut);
+
+builder.Build().Run();
+```
+
+### Example 2: Add Papercut SMTP with user-defined ports
+
+```csharp
+var builder = DistributedApplication.CreateBuilder(args);
+
+var papercut = builder.AddPapercutSmtp("papercut", 80, 25);
+
+var xyz = builder.AddProject("application")
+ .WithReference(papercut)
+ .WaitFor(papercut);
+
+builder.Build().Run();
+```
