-APM is available through three tiers: APM, APM Pro, and APM Enterprise. APM gives you deep visibility into your applications, with distributed tracing capabilities, seamless correlation between traces, logs, and other telemetry, and out-of-the-box performance dashboards for your service. With Continuous Profiler in APM Enterprise, you can pinpoint the slowest and most resource-intensive methods, in aggregate at the service and endpoint levels, as well as for every distributed trace. With Data Streams Monitoring (DSM) in APM Pro and APM Enterprise, you can easily track the end-to-end performance of your data streaming pipelines and event-driven applications that use Kafka, SQS, and RabbitMQ.

    - One profiled container is a container that is running the Continuous Profiler service. This does not include containers that are not being profiled. For instance, a DNS service container that is NOT profiled, running concurrently with your application container that IS profiled, is not counted towards the four profiler containers allotment.

With distributed tracing, out-of-the-box dashboards, and correlation with other telemetry data, Datadog APM helps you maintain performance and improve user experience.
 
 For an introduction to terminology used in Datadog APM, see [APM Terms and Concepts][1].
 
 ## Getting started
 
-The simplest way to start with Datadog APM is with Single Step Instrumentation. This approach installs the Datadog Agent and instruments your application in one step, with no additional configuration steps required. To learn more, read [Single Step Instrumentation][27].
+To get started with APM, use [Single Step Instrumentation][27]. This installs the Datadog Agent and instruments your application in one step, enabling full distributed tracing with no additional configuration required.
 
 For setups that require more customization, Datadog supports custom instrumentation with Datadog SDKs and [Dynamic Instrumentation][30] in the Datadog UI. To learn more, read [Application Instrumentation][2].
 
+If some parts of your system are not instrumented—such as legacy systems, third-party services, or environments where instrumentation is impractical or unnecessary—[APM Basic][31] provides baseline service visibility by collecting RED metrics from network traffic. It is also suitable for staging or other environments where full instrumentation is not required.
