+Contributing to PyCNN
+============================
+
+**Note: This document is a 'getting started' summary for contributing code,
+documentation, testing, and filing issues. ** Please read this carefully to help make
+the code review process go as smoothly as possible and maximize the
+likelihood of your contribution being merged.**
+
+How to contribute
+-----------------
+
+The preferred workflow for contributing to PyCNN is to fork the 
+[main repository](https://github.com/ankitaggarwal011/PyCNN.git) on
+GitHub, clone, and develop on a branch. Steps:
+
+1. Fork the [project repository](https://github.com/ankitaggarwal011/PyCNN.git)
+   by clicking on the 'Fork' button near the top right of the page. This creates
+   a copy of the code under your GitHub user account.
+
+2. Clone your fork of the PyCNN repo from your GitHub account to your local disk:
+
+   ```bash
+   $ git clone [email protected]:YourLogin/PyCNN.git
+   $ cd PyCNN
+   ```
+
+3. Create a ``changes`` branch to hold your development changes:
+
+   ```bash
+   $ git checkout -b my-changes
+   ```
+
+   Always use a ``cahnges`` branch. It's good practice to never work on the ``master`` branch!
+
+4. Develop the feature on your changes branch. Add changed files using ``git add`` and then ``git commit`` files:
+
+   ```bash
+   $ git add modified_files
+   $ git commit
+   ```
+
+   to record your changes in Git, then push the changes to your GitHub account with:
+
+   ```bash
+   $ git push -u origin my-changes
+   ```
+
+5. Go to the GitHub web page of your fork of the PyCNN repo.
+Click the 'Pull request' button to send your changes to the project's maintainers for
+review. This will send an email to the committers.
+
+(If any of the above seems like magic to you, please look up the 
+[Git documentation](https://git-scm.com/documentation) on the web, or ask a friend or another contributor for help.)

+New contributor tips

+
+A great way to start contributing to PyCNN is to pick an item
+from the list of [Easy issues](https://github.com/ankitaggarwal011/PyCNN/issues)
+in the issue tracker. Resolving these issues allow you to start
+contributing to the project without much prior knowledge. Your
+assistance in this area will be greatly appreciated by the more
+experienced developers as it helps free up their time to concentrate on
+other issues.
