 Trace the history of an individual method in a git repository (experimental).
 
 ### Requirements
 
-* Ruby >= v1.9.3 (due to requirements of the `rugged` gem)
+* Ruby >= v2.0.0 (due to requirements of the `parser` gem); although parsing of source code for Ruby >= v1.8 is possible
 * The [rugged](https://github.com/libgit2/rugged) Ruby gem (listed as dependency in gemspec)
 * The [libgit2](https://github.com/libgit2/libgit2) C library (included as part of rugged gem)
 * The [parser](https://github.com/whitequark/parser) Ruby gem (listed as dependency in gemspec)
 
 ### Install
 
     gem install method_log
 
 ### Run
 
-    $ method_log <options> <method-signature>
-    
-    # options:
-    --patch, -p:                                  Generate patch.
-    --ruby-version, -r <s>:                       Parser Ruby version (18, 19, 20, 21) (default: current)
-    --max-count, -n <i>:                          Limit the number of commits to output.
-    --stop-at-latest-introduction-of-method, -s:  Stop at lastest introduction of method.
-    --help, -h:                                   Show usage.
-    
-    # method-signature
-    Uses the Ruby Index format e.g. Foo#bar, Bar::Baz#foo, Baz.foo.
+#### Display the commit history for a single method
 
-### Todo
+    $ method_log [options] <method-signature>
 
-* Support for Rspec tests
+#### Build a parallel git repository of method definitions
+
+    $ build_methods_repo [options] <source-repo-path> <target-repo-path>
+
+### To Do
+
+* Parsing support for RSpec tests
 * Default to looking for commits in current git branch
 * Check what happens with merge commits
 * Maybe add as new git command or extension to existing command e.g. `git log`
 * Find "similar" method implementations e.g. by comparing ASTs of implementations
