+## What is DevTools?
+
+DevTools is a suite of performance and debugging tools
+for Dart and Flutter.
+_Flutter DevTools_ and _Dart DevTools_ refer to the
+same set of tools.
+
+![Dart DevTools Screens](/assets/images/docs/tools/devtools/dart-devtools.gif){:width="100%"}
+
+For a video introduction to DevTools, check out
+the following deep dive and use-case walkthrough:
+
+<iframe width="560" height="315" src="{{site.yt.embed}}/_EYk-E29edo" title="Dive in to Flutter DevTools" {{site.yt.set}}></iframe>
+
+[Dive in to DevTools]({{site.yt.watch}}?v=_EYk-E29edo)
+
+## What can I do with DevTools?
+
+Here are some of the things you can do with DevTools:
+
+* Inspect the UI layout and state of a Flutter app.
+* Diagnose UI jank performance issues in a Flutter app.
+* CPU profiling for a Flutter or Dart app.
+* Network profiling for a Flutter app.
+* Source-level debugging of a Flutter or Dart app.
+* Debug memory issues in a Flutter or Dart
+  command-line app.
+* View general log and diagnostics information
+  about a running Flutter or Dart
+  command-line app.
+* Analyze code and app size.
+* Validate deep links in your Android app.
+
+We expect you to use DevTools in conjunction with
+your existing IDE or command-line based development workflow.

+<a id="install-devtools"></a>
+
+## How to launch DevTools {:#start}
+
+See the [VS Code][], [Android Studio/IntelliJ][], or
+[command line][] pages for instructions on how to launch DevTools.
+
+## Troubleshooting some standard issues
+
+**Question**: My app looks janky or stutters.
+  How do I fix it?
+
+**Answer**: Performance issues can cause [UI frames][]
+  to be janky and/or slow down some operations.
+
+  1. To detect which code impacts concrete late frames,
+     start at [Performance > Timeline][].
+  2. To learn which code takes the most CPU time in
+     the background, use the [CPU profiler][].
+
+For more information, check out the
+[Performance][] page.
+
+**Question**: I see a lot of garbage collection (GC) events occurring.
+  Is this a problem?
+
+**Answer**: Frequent GC events might display on
+  the DevTools > Memory > Memory chart. In most cases,
+  it's not a problem.
+
+If your app has frequent background activity with some idle time,
+Flutter might use that opportunity to collect the created objects
+without performance impact.
