-This directory contains prebuilt Dart SDK packages downloaded from
-[CIPD](https://github.com/luci/luci-go/tree/master/cipd).
-These are built by Fuchsia [bots](https://luci-milo.appspot.com/p/fuchsia/g/dart-prebuilt/console)
-using a [recipe](https://fuchsia.googlesource.com/infra/recipes/+/master/recipes/dart_toolchain.py).
-
-The prebuilt version must match the sources in //third_party/dart exactly.
-The [`update.py` script](update.py) downloads a package for the build host
-that matches the current Dart revision according to `jiri project`. It's
-run automatically by the Jiri [manifest](../../manifest/minimal) but can
-also be run by hand at any time. Run it with `--help` for details.
-
-If there is no prebuilt for your build host, then you'll have to supply your
-own. It's a normal `dart-sdk` built for the build host, but it also needs
-`bin/gen_shapshot.OS-CPU` and `bin/gen_shapshot_product.OS-CPU`. These run
-on the build host but target a corresponding Dart VM built for `OS-CPU`.
-The Fuchsia GN build will run those for both `$host_os-$host_cpu`
-(e.g. `linux-x64`) and `$target_os-$target_cpu` (e.g. `fuchsia-arm64`).
-This all must be built from Dart sources that exactly match the version in
-//third_dart/dart that will be built in the Fuchsia GN build.
-
-The GN build argument `prebuilt_dart_sdk` sets the directory where GN will
-look for Dart. Its default is the `$host_os-$host_cpu` subdirectory here,
-where the [`update.py` script](update.py) unpacks it by default. To use a
-different build of Dart, just set that in `args.gn`.
