+#### Cloud Client Using MTLS
+
+Assuming a client certificate is present at `my-cert.pem` and a client key is present at `my-key.pem`, this is how to
+connect to Temporal Cloud:
+
+```csharp
+using Temporalio.Client;
+
+var client = await TemporalClient.ConnectAsync(new("my-namespace.a1b2c.tmprl.cloud:7233")
+{
