Fix readme for frog.

README.txt

 To use frog:
 
-1) Create a symbol link for the VM:
-  # From the frog folder:
-  mkdir bin
-  ln -s $DART/$OUTDIR_PREFIX/Release_ia32/dart_bin bin/dart_bin
+1) Frog is now included in the checkout of the public repo of the bleeding_edge
+   branch. The code will be located under $DART/frog.
 
-2) Make sure you have 'node' in your path (http://nodejs.org/, and
+   Note that $DART/frog/ is a separate dependency in 'all.deps/DEPS', for this
+   reason changes in the frog directory will have to be submitted separately
+   from changes to the rest of the dart repo.
+
+   (git users): If you'd prefer to use git, you can do the following to have a
+   git setup for the frog subdirectory:
+  $ rm -rf $DART/frog/
+  $ cd $DART
+  $ git svn clone -rHEAD https://dart.googlecode.com/svn/experimental/frog frog
+
+2) Create a symbol link for the VM:
+  $ cd $DART/frog/
+  $ mkdir bin
+  $ ln -s $DART/$OUTDIR_PREFIX/Release_ia32/dart_bin bin/dart_bin
+
+3) Make sure you have 'node' in your path (http://nodejs.org/, and
    https://github.com/joyent/node/wiki/Installation for how to install)
 
 You can then do:
-$ ../tools/build.py --mode=release,debug frog
-$ ../tools/test.py --report -t 5 -p color --mode=release,debug frog
+  $ ../tools/build.py --mode=release,debug
+  $ ../tools/test.py --report -t 5 -p color --mode=release,debug frog
 
 The 'release' version of frog is the self-hosted frog.
 The 'debug' version of frog is frog running on the VM.
 
 To use the self-hosted compiler called frogsh (for frog self-hosted), run:
 
-./frog.py --js_out=frogsh -- frog.dart
+  $ ./frog.py --js_out=frogsh -- frog.dart
 
 (this will make frogsh the same as 
 $DART/frog/$OUTDIR_PREFIX/Release_ia32/dart_bin)
 
 It is recommended that you run this command on every commit.
 
 To run the self-hosted compiler, you can just type frogsh.
 
-> ./frogsh tests/hello.dart
-hello world
+  $ ./frogsh tests/hello.dart
+This should print 'hello world'.
 
 Running html tests:
-> ./frog.py --html -- tests/htmltest.dart
-> ./frog.py --html -- tests/canvastest.dart
+  $ ./frog.py --html -- tests/htmltest.dart
+  $ ./frog.py --html -- tests/canvastest.dart
