 # Microsoft OpenTelemetry exporter for Azure Monitor
 
-The exporter for Azure Monitor allows you to export data utilizing the OpenTelemetry SDK and send telemetry data to Azure Monitor for applications written in Python.
+The exporter for Azure Monitor allows Python applications to export data from the OpenTelemetry SDK to Azure Monitor. The exporter is intended for users who require advanced configuration or has more complicated telemetry needs that require all of distributed tracing, logging and metrics. If you have simpler configuration requirements, we recommend using the [Azure Monitor OpenTelemetry Distro](https://learn.microsoft.com/azure/azure-monitor/app/opentelemetry-enable?tabs=python) instead for a simpler one-line setup.
+
+Prior to using this SDK, please read and understand [Data Collection Basics](https://learn.microsoft.com/azure/azure-monitor/app/opentelemetry-overview?tabs=python), especially the section on [telemetry types](https://learn.microsoft.com/azure/azure-monitor/app/opentelemetry-overview?tabs=python#telemetry-types). OpenTelemetry terminology differs from Application Insights terminology so it is important to understand the way the telemetry types map to each other.

 # Azure Monitor Opentelemetry Distro client library for Python
 
-The Azure Monitor Distro of [Opentelemetry Python][ot_sdk_python] provides multiple installable components available for an Opentelemetry Azure Monitor monitoring solution. It allows you to instrument your Python applications to capture and report telemetry to Azure Monitor via the Azure monitor exporters.
+The Azure Monitor Distro of [Opentelemetry Python][ot_sdk_python] is a "one-stop-shop" telemetry solution, requiring only one line of code to instrument your application. The distro captures telemetry via [OpenTelemetry instrumentations][azure_monitor_opentelemetry_exporters] and reports telemetry to Azure Monitor via the [Azure Monitor exporters][azure_monitor_opentelemetry_exporters].
