-With [tracing](/product/performance/), Sentry tracks your software performance, measuring metrics like throughput and latency, and displaying the impact of errors across multiple systems. Sentry captures distributed traces consisting of transactions and spans, which measure individual services and individual operations within those services. Learn more about our model in [Distributed Tracing](/product/sentry-basics/tracing/distributed-tracing/).
+## Prerequisites
 
-<Note>
+* You have the <PlatformLink to="/">Python SDK installed</PlatformLink> (version 0.11.2 or higher)
 
-If you’re adopting Tracing in a high-throughput environment, we recommend testing prior to deployment to ensure that your service’s performance characteristics maintain expectations.
+## Configure
 
-</Note>
+To enable tracing in your application, adjust the `traces_sample_rate` based on the number of trace samples you want to send to Sentry by adding the highlighted code snippet below. (Setting a value of `1.0` will send 100% of your traces.)
