-Both ``pip`` and ``setup.py`` installs cdiff to system wide directory, if you
-want a minimal tool without the boring external dependencies (like me), just
-save `cdiff.py <https://raw.github.com/ymattw/cdiff/master/cdiff.py>`_ to
+Just save `cdiff.py <https://raw.github.com/ymattw/cdiff/master/cdiff.py>`_ to
 whatever directory which is in your ``$PATH``, for example, ``$HOME/bin`` is in
 my ``$PATH``, so I save the script there and name as ``cdiff``.
 
 Usage
 -----
 
-Cdiff reads diff from diff (patch) file if given, or stdin if redirected, or
-diff produced by revision tool if in a git/svn/hg workspace.  Use option ``-s``
-to enable side by side view, and option ``-w N`` to set a text width other than
-default ``80``.  See examples below.

+Read diff from local modification in a *svn*, *git*, or *hg* workspace:
 
 .. code:: sh
 
     cd proj-workspace
-    cdiff                   # view colored incremental udiff
-    cdiff -s                # view side by side
-    cdiff -s -w 90          # use text width 90 other than default 80

+    cdiff -s                    # view side by side

 Pipe in a diff:
 
     cdiff foo.patch -s
     cdiff foo.patch -s -w 90
 
-View diff between two files (wrapper of ``diff``)::
+View diff between two files (wrapper of ``diff``):
+
+.. code:: sh
 
-    cdiff foo foo.new       # equivalent to diff -u foo foo.new | cdiff
+    cdiff foo foo.new           # equivalent to diff -u foo foo.new | cdiff
     cdiff foo foo.new -s
 
 Redirect output to another patch file is safe:
 - Only takes unified diff for input
 - Side by side mode has alignment problem for wide chars
 
-Pull request is very welcome, make sure run ``make test`` to verify.  Single
-commit in pull request would make it easier for review, for example to collapse
-last 3 commits into 1 before *push*, use ``git rebase -i HEAD~3``, *pick* the
-first and *squash* the other two.
