 ## Examples
 
-<!-- Pending Sample Creation -->
+### Sync examples
+
+- [List repositories](#list-repositories)
+
+### Async examples
+
+- [List repositories asynchronously](#list-repositories-asynchronously)
+
+### List repositories
+
+Iterate through the collection of repositories in the registry.
+
+```C# Snippet:ContainerRegistry_Tests_Samples_CreateClient
+// Get the service endpoint from the environment
+Uri endpoint = new Uri(Environment.GetEnvironmentVariable("REGISTRY_ENDPOINT"));
+
+// Create a new ContainerRegistryClient
+ContainerRegistryClient client = new ContainerRegistryClient(endpoint, new DefaultAzureCredential());
+
+// Perform an operation
+Pageable<string> repositories = client.GetRepositories();
+foreach (string repository in repositories)
+{
+    Console.WriteLine(repository);
+}
+```
+
+### List repositories asynchronously
+
+The asynchronous APIs are identical to their synchronous counterparts, but methods end with the standard .NET "Async" suffix and return a Task.
+
+```C# Snippet:ContainerRegistry_Tests_Samples_CreateClientAsync
+// Get the service endpoint from the environment
+Uri endpoint = new Uri(Environment.GetEnvironmentVariable("REGISTRY_ENDPOINT"));
+
+// Create a new ContainerRegistryClient
+ContainerRegistryClient client = new ContainerRegistryClient(endpoint, new DefaultAzureCredential());
+
+// Perform an operation
+AsyncPageable<string> repositories = client.GetRepositoriesAsync();
+await foreach (string repository in repositories)
+{
+    Console.WriteLine(repository);
+}
+```
 
 ## Troubleshooting
 
 All container registry service operations will throw a
 [RequestFailedException][RequestFailedException] on failure.
 
+```C# Snippet:ContainerRegistry_Tests_Samples_HandleErrors
+Uri endpoint = new Uri(Environment.GetEnvironmentVariable("REGISTRY_ENDPOINT"));
+
+// Create an invalid ContainerRepositoryClient
+string fakeRepositoryName = "doesnotexist";
+ContainerRepositoryClient client = new ContainerRepositoryClient(endpoint, fakeRepositoryName, new DefaultAzureCredential());
+
+try
+{
+    client.GetProperties();
+}
+catch (RequestFailedException ex) when (ex.Status == 404)
+{
+    Console.WriteLine("Repository wasn't found.");
+}
+```
+
+You can also easily [enable console logging](https://github.com/Azure/azure-sdk-for-net/blob/master/sdk/core/Azure.Core/samples/Diagnostics.md#logging) if you want to dig
+deeper into the requests you're making against the service.
