-Getting Kernel
-------------
-
-Checkout the repository and run pub get:
-```bash
-git clone https://github.com/dart-lang/kernel
-cd kernel
-pub get
-```
-
-Command-Line Tool
------------------
-
-Run `tool/dartk.dart` from the command-line to convert between .dart files
-and the serialized binary and textual formats.
-
-`dartk` expects the `.dill` extension for files in the binary format.
-The textual format has no preferred extension right now.
-
-Example commands:
-```bash
-dartk foo.dart # print text IR for foo.dart
-dartk foo.dart -ofoo.dill # write binary IR for foo.dart to foo.dill
-dartk foo.dill # print text IR for binary file foo.dill
-```
-
-Pass the `--link` or `-l` flag to link all transitive dependencies into one file:
-```bash
-dartk myapp.dart -ppackages -l -omyapp.dill # Bundle everything.
-dartk myapp.dill # Print it back out in a (very, very long) textual format.
-```
-
See [ast.dart](lib/ast.dart) for the in-memory IR, or [binary.md](binary.md) for
a description of the binary format. For now, the textual format is very ad-hoc
and cannot be parsed back in.
-
-
-Testing
--------
-
-If you plan to make changes to kernel, get a checkout of the Dartk SDK and run:
-```bash
-tool/regenerate_dill_files.dart --sdk <path to SDK checkout>
-pub run test
-```
-
-
-Linking
--------------------------
-Linking from binary files is not yet implemented. In order to compile a whole
-program, currently everything must be compiled from source at once.
