+# Samples for Azure Anomaly Detector client library for Python
+
+These code samples show common scenario operations with the Anomaly Detector client library.
+
+These sample programs show common scenarios for the Anomaly Detector client's offerings.
+
+|**File Name**|**Description**|
+|----------------|-------------|
+|[sample_detect_entire_series_anomaly.py][sample_detect_entire_series_anomaly] |Detecting anomalies in the entire time series.|
+|[sample_detect_last_point_anomaly.py][sample_detect_last_point_anomaly] |Detecting the anomaly status of the latest data point.|
+|[sample_detect_change_point.py][sample_detect_change_point] |Detecting change points in the entire time series.|
+
+## Prerequisites
+* Python 2.7 or 3.5 or higher is required to use this package.
+* The Pandas data analysis library.
+* You must have an [Azure subscription][azure_subscription] and an
+[Azure Anomaly Detector account][azure_anomaly_detector_account] to run these samples.
+
+## Setup
+
+1. Install the Azure Anomaly Detector client library for Python with [pip][pip]:
+
+```bash
+pip install azure-ai-anomalydetector
+```
+
+2. Clone or download this sample repository
+3. Open the sample folder in Visual Studio Code or your IDE of choice.
+
+## Running the samples
+
+1. Open a terminal window and `cd` to the directory that the samples are saved in.
+2. Set the environment variables specified in the sample file you wish to run.
+3. Follow the usage described in the file, e.g. `python sample_detect_entire_series_anomaly.py`
+
+## Next steps
+
+Check out the [API reference documentation][python-fr-ref-docs] to learn more about
+what you can do with the Azure Anomaly Detector client library.
