-```bash

 ## Create an Outline File
 
-1. Run `dart pkg/front_end/lib/src/fasta/bin/outline.dart pkg/compiler/lib/src/dart2js.dart`
+1. Run `./pkg/front_end/tool/fasta outline pkg/compiler/lib/src/dart2js.dart`
 
-2. Optionally, run `dart pkg/kernel/bin/dartk.dart pkg/compiler/lib/src/dart2js.dart.dill` to view the generated outline.

-This will generate a file named `pkg/compiler/lib/src/dart2js.dart.dill` which contains a serialized reprsentation of the input program excluding method bodies. This is similar to an analyzer summary.

 ## Create a Platform Dill File
 
-A `platform.dill` is a dill file that contains the Dart SDK platform libraries. For now, this is generated with dartk until fasta reaches a higher rate of test passes.

 ## Compiling a Program
 
 ```bash

+./pkg/front_end/tool/fasta compile pkg/front_end/test/fasta/hello.dart

 This will generate `pkg/front_end/test/fasta/hello.dart.dill` which can be run this way:
 
 ```bash

+./pkg/front_end/tool/fasta analyzer-compile pkg/front_end/test/fasta/hello.dart
