 ## Runtime Flame Graph: `tracing` spans
 
-Bevy has built-in [tracing](https://github.com/tokio-rs/tracing) spans to make it cheap and easy to profile Bevy ECS systems, render logic, engine iternals, and user app code. Enable the `trace` cargo feature to enable Bevy's built-in spans. You also need to select a `tracing` backend using the following cargo features:

+If you also want to include `wgpu` tracing spans when profiling, they are emitted at the `tracing` `info` level so you will need to make sure they are not filtered out by the `LogSettings` resource's `filter` member which defaults to `wgpu=error`. You can do this by setting the `RUST_LOG=info` environment variable when running your application.

+
+The [Tracy profiling tool](https://github.com/wolfpld/tracy) is:
+> A real time, nanosecond resolution, remote telemetry, hybrid frame and sampling profiler for games and other applications.
+
+There are binaries available for Windows, and installation / build instructions for other operating systems can be found in the [Tracy documentation PDF](https://github.com/wolfpld/tracy/releases/latest/download/tracy.pdf).
+
+It has a command line capture tool that can record the execution of graphical applications, saving it as a profile file. Tracy has a GUI to inspect these profile files. The GUI app also supports live capture, showing you in real time the trace of your app.
+
+In one terminal, run:
+`./capture-release -o my_capture.tracy`
+This will sit and wait for a tracy-instrumented application to start, and when it does, it will automatically connect and start capturing. Note that on Windows, the capture tool is called `capture.exe`.
+
+Then run your application, enabling the `trace_tracy` feature:
+`cargo run --release --features bevy/trace_tracy`
+
+After running your app, you can open the captured profile file (`my_capture.tracy` in the example above) in the Tracy GUI application to see a timeline of the executed spans.
+
+Alternatively, directly run the tracy GUI and then run your application, for live capture. However, beware that running the live capture on the same machine will be a competing graphical application, which may impact results. Pre-recording the profile data through the CLI tool is recommended for more accurate traces.
+
+In any case, you'll see your trace in the GUI window:

+
+There is a button to display statistics of mean time per call (MTPC) for all systems:

+
+Or you can select an individual system and inspect its statistics (available through the "statistics" button in the top menu) to see things like the distribution of execution times in a graph, or statistical aggregates such as mean, median, standard deviation, etc. It will look something like this:

 ### Adding your own spans
 
 Add spans to your app like this (these are in `bevy::prelude::*` and `bevy::log::*`, just like the normal logging macros).
 
 ```rust
 {
-  // creates a span and starts the timer 
+  // creates a span and starts the timer
   let my_span = info_span!("span_name", name = "span_name").entered();
   do_something_here();
 } // my_span is dropped here ... this stops the timer
