+# Frequent Polling Activity
+
+This sample demonstrates how to implement a frequent polling mechanism
+(1 second or faster) inside an Activity.
+The implementation is a loop that polls a service and then sleeps for the poll
+interval (1 second in the sample).
+
+## How to Run
+
+1. **Start the Worker:**
+
+    Open a terminal and run the following command to start the worker process.
+    The worker will listen for tasks on the `frequent-polling-sample` task queue.
+
+    ```bash
+      bundle exec ruby worker.rb
+    ```
+
+    You will see the worker log messages indicating it is calling the service.
+    It will try several times, with a short delay between each attempt.
+
+2. **Start the Workflow:**
+
+    In a separate terminal, run this command to start the workflow.
+    This script will start the workflow and wait for its completion,
+    printing the final result.
+
+    ```bash
+      bundle exec ruby starter.rb
+    ```
+
+    After a few seconds, the service will succeed.
+    You will see the final result printed in the starter's terminal,
+    and the worker will log the successful completion.

+# Periodic Polling of a Sequence of Activities
+
+This sample demonstrates how to use a Child Workflow for periodic Activity polling.
+
+This is a rare scenario where polling requires execution of a Sequence of Activities, or Activity arguments need to change between polling retries. For this case we use a Child Workflow to call polling activities a set number of times in a loop and then periodically call Continue-As-New.
+
+## How to Run
+
+To run, first see [README.md](../README.md) for prerequisites.
+
+1. **Start the Worker:**
+
+    Open a terminal and run the following command to start the worker process.
+    The worker will listen for tasks on the `frequent-polling-sample` task queue.
+
+    ```bash
+      bundle exec ruby worker.rb
+    ```
+
+    You will see the worker log messages indicating it is calling the service.
+    It will try several times, with a short delay between each attempt.
+
+2. **Start the Workflow:**
+
+    In a separate terminal, run this command to start the workflow.
+    This script will start the workflow and wait for its completion,
+    printing the final result.
+
+    ```bash
+      bundle exec ruby starter.rb
+    ```
+
+    After a few seconds, the service will succeed.
+    You will see the final result printed in the starter's terminal,
+    and the worker will log the successful completion.
