+We have set up a [milestone][communityMilestone] for issues which we believe are an excellent
 place to start if you are interested in contributing to AngularDart.
 
 We'd love for you to contribute to our source code and to make AngularDart even better than it is
 today! Here are the guidelines we'd like you to follow:
 
- - [Code of Conduct](#coc)
- - [Question or Problem?](#question)
- - [Issues and Bugs](#issue)
- - [Feature Requests](#feature)

 Help us keep Angular open and inclusive. Please read and follow our [Code of Conduct][coc].

 If you have questions about how to use AngularDart, please direct these to the [Google Group][groups]
 discussion list or [StackOverflow][stackoverflow].

+## Found an Issue?
 If you find a bug in the source code or a mistake in the documentation, you can help us by
 submitting and issue to our [GitHub Repository][github]. Even better you can submit a Pull Request
 with a fix.
 
 **Please see the Submission Guidelines below**.

+## Want a Feature?
 You can request a new feature by submitting an issue to our [GitHub Repository][github].  If you
 would like to implement a new feature then consider what kind of change it is:
 
 <!--
 * **Major Changes** that you wish to contribute to the project should be discussed first on our
 [dev mailing list][angular-dev] or [IRC][irc] so that we can better coordinate our efforts, prevent
 duplication of work, and help you to craft the change so that it is successfully accepted into the
 project.
 -->
 * **Small Changes** can be crafted and submitted to [GitHub Repository][github] as a Pull Request.

+## Want a Doc Fix?
 If you want to help improve the docs, it's a good idea to let others know what you're working on to
 minimize duplication of effort. Before starting, check out the issue queue.
 
 Comment on an issue to let others know what you're working on, or create a new issue if your work
 doesn't fit within the scope of any of the existing doc fix projects.
 
 For large fixes, please build and test the documentation before submitting the PR to be sure you haven't

 ### Submitting an Issue
 Before you submit your issue search the archive, maybe your question was already answered.
 
 If your issue appears to be a bug, and hasn't been reported, open a new issue.
 Help us to maximize the effort we can spend fixing issues and adding new
 features, by not reporting duplicate issues.  Providing the following information will increase the
 chances of your issue being dealt with quickly:
 
 * **Overview of the issue** - if an error is being thrown a non-minified stack trace helps
 * **Motivation for or Use Case** - explain why this is a bug for you
 * **Angular Version(s)** - is it a regression?
 * **Browsers and Operating System** - is this a problem with all browsers or only IE8?
 * **Reproduce the error** - provide a live example (using [Runnable][runnable]) or a unambiguous set of steps.
 * **Related issues** - has a similar issue been reported before?
 * **Suggest a Fix** - if you can't fix the bug yourself, perhaps you can point to what might be
   causing the problem (line of code or commit)
 
 **If you get help, help others. Good karma rulez!**
 
 ### Submitting a Pull Request
 Before you submit your pull request consider the following guidelines:
 
-* Search [GitHub](https://github.com/angular/angular.dart/pulls) for an open or closed Pull Request
+* Search [GitHub][github] for an open or closed Pull Request
   that relates to your submission. You don't want to duplicate effort.
 * Please sign our [Contributor License Agreement (CLA)](#signing-the-cla) before sending pull
   requests. We cannot accept code without this.
 * Make your changes in a new git branch
 
      ```shell
      git checkout -b my-fix-branch master
      ```
 
-* Create your patch, **including appropriate test cases**.
-* Follow our [Coding Rules](#coding-rules).
-* Run the full Angular test suite, as described in the [developer documentation][dev-doc],
-  and ensure that all tests pass.
-* Commit your changes using a descriptive commit message that follows our
-  [commit message conventions](#commit-message-format) and passes our commit message presubmit hook
-  `validate-commit-msg.js`. Adherence to the [commit message conventions](#commit-message-format)
-  is required because release notes are automatically generated from these messages.
+* Create your patch, including appropriate test cases.

+  `validate-commit-msg.js`):
 
      ```shell

      ```
-  Note: the optional commit `-a` command line option will automatically "add" and "rm" edited files.

     ```
 
-* In GitHub, send a pull request to `angular:master`.
-* If we suggest changes then 
-  * Make the required updates.
-  * Re-run the AngularDart test suite to ensure tests are still passing.
-  * Rebase your branch and force push to your GitHub repository (this will update your Pull Request):
+* In Github, send a pull request to `angular:master`.
+* If we suggest changes then you can modify your branch, rebase and force a new push to your GitHub

     ```
 
 That's it! Thank you for your contribution!

-After your pull request is merged, you can safely delete your branch and pull the changes
+When the patch is reviewed and merged, you can safely delete your branch and pull the changes
 from the main (upstream) repository:
 
-* Delete the remote branch on GitHub either through the GitHub web UI or your local shell as follows:
+* Delete the remote branch on Github:
 
     ```shell
     git push origin --delete my-fix-branch

     ```
 
 * Delete the local branch:
 
     ```shell
     git branch -D my-fix-branch
     ```
 
 * Update your master with the latest upstream version:
 
     ```shell
     git pull --ff upstream master
     ```

-## <a name="rules"></a> Coding Rules
+## Coding Rules
 To ensure consistency throughout the source code, keep these rules in mind as you are working:
 
   * All features or bug fixes **must be tested** by one or more [specs][unit-testing].
   * All public API methods **must be documented** with [doc comments][doc-comments].
   * With the exceptions listed below, we follow the rules contained in
   [Google's Dart Style Guide][dart-style-guide].
 
-## <a name="commit"></a> Git Commit Guidelines
+## Git Commit Guidelines
 
 We have very precise rules over how our git commit messages can be formatted.  This leads to **more
 readable messages** that are easy to follow when looking through the **project history**.  But also,
 we use the git commit messages to **generate the AngularDart change log**.
 
 ### Commit Message Format
 Each commit message consists of a **header**, a **body** and a **footer**.  The header has a special
 format that includes a **type**, a **scope** and a **subject**:
 
 ```
@@ skipping 36 matching lines @@
 Just as in the **subject**, use the imperative, present tense: "change" not "changed" nor "changes"
 The body should include the motivation for the change and contrast this with previous behavior.
 
 ###Footer
 The footer should contain any information about **Breaking Changes** and is also the place to
 reference GitHub issues that this commit **Closes**.
 
 
 A detailed explanation can be found in this [document][commit-message-format].
