-# Contributing
-
-Want to contribute to Polymer? Great!

-## Initial setup
-
-Here's an easy guide that should get you up and running:
-
-1. Setup Grunt: `sudo npm install -g grunt-cli`
-1. Fork the project on github and pull down your copy.
-   > replace the {{ username }} with your username and {{ repository }} with the repository name
-
-        git clone git@github.com:{{ username }}/{{ repository }}.git --recursive
-
-    Note the `--recursive`. This is necessary for submodules to initialize properly. If you don't do a recursive clone, you'll have to init them manually:
-
-        git submodule init
-        git submodule update
-
-    Download and run the `pull-all.sh` script to install the sibling dependencies.
-
-        git clone git://github.com/Polymer/tools.git && tools/bin/pull-all.sh
-
-1. Test your change
-   > in the repo you've made changes to, run the tests:
-
-        cd $REPO
-        npm install
-        grunt test
-
-1. Commit your code and make a pull request.
-
-That's it for the one time setup. Now you're ready to make a change.
-
-## Submitting a pull request
-
-We iterate fast! To avoid potential merge conflicts, it's a good idea to pull from the main project before making a change and submitting a pull request. The easiest way to do this is setup a remote called `upstream` and do a pull before working on a change:
-
-    git remote add upstream git://github.com/Polymer/{{ repository }}.git
-
-Then before making a change, do a pull from the upstream `master` branch:
-
-    git pull upstream master
-
-To make life easier, add a "pull upstream" alias in your `.gitconfig`:
-
-    [alias]
-      pu = !"git fetch origin -v; git fetch upstream -v; git merge upstream/master"
-
-That will pull in changes from your forked repo, the main (upstream) repo, and merge the two. Then it's just a matter of running `git pu` before a change and pushing to your repo:
-
-    git checkout master
-    git pu
-    # make change
-    git commit -a -m 'Awesome things.'
-    git push
-
-Lastly, don't forget to submit the pull request.
