+# Contributing to normalize.css
+
+Please take a moment to review this document in order to make the contribution
+process easy and effective for everyone involved.
+
+Following these guidelines helps to communicate that you respect the time of
+the developers managing and developing this open source project. In return,
+they should reciprocate that respect in addressing your issue or assessing
+patches and features.
+
+
+## Using the issue tracker
+
+The issue tracker is the preferred channel for [bug reports](#bugs),
+[features requests](#features) and [submitting pull
+requests](#pull-requests), but please respect the following restrictions:
+
+* Please **do not** use the issue tracker for personal support requests.
+
+* Please **do not** derail or troll issues. Keep the discussion on topic and
+  respect the opinions of others.
+
+
+<a name="bugs"></a>
+## Bug reports
+
+A bug is a _demonstrable problem_ that is caused by the code in the repository.
+Good bug reports are extremely helpful - thank you!
+
+Guidelines for bug reports:
+
+1. **Use the GitHub issue search** – check if the issue has already been
+   reported.
+
+2. **Check if the issue has been fixed** – try to reproduce it using the
+   latest `master` branch in the repository.
+
+3. **Isolate the problem** – create a live example (e.g., on
+   [Codepen](http://codepen.io)) of a [reduced test
+   case](http://css-tricks.com/6263-reduced-test-cases/).
+
+A good bug report shouldn't leave others needing to chase you up for more
+information. Please try to be as detailed as possible in your report. What is
+your environment? What steps will reproduce the issue? What browser(s) and OS
+experience the problem? What would you expect to be the outcome? All these
+details will help people to fix any potential bugs.
+
+Example:
+
+> Short and descriptive example bug report title
+>
+> A summary of the issue and the browser/OS environment in which it occurs. If
+> suitable, include the steps required to reproduce the bug.
+>
+> 1. This is the first step
+> 2. This is the second step
+> 3. Further steps, etc.
+>
+> `<url>` - a link to the reduced test case
+>
+> Any other information you want to share that is relevant to the issue being
+> reported. This might include the lines of code that you have identified as
+> causing the bug, and potential solutions (and your opinions on their
+> merits).
+
+
+<a name="features"></a>
+## Feature requests
+
+Feature requests are welcome. But take a moment to find out whether your idea
+fits with the scope and aims of the project. It's up to *you* to make a strong
+case to convince the project's developers of the merits of this feature. Please
+provide as much detail and context as possible.
+
+
+<a name="pull-requests"></a>
+## Pull requests
+
+Good pull requests - patches, improvements, new features - are a fantastic
+help. They should remain focused in scope and avoid containing unrelated
+commits.
+
+**Please ask first** before embarking on any significant work, otherwise you
+risk spending a lot of time working on something that the project's developers
+might not want to merge into the project.
+
+Please adhere to the coding conventions used throughout a project (whitespace,
+accurate comments, etc.) and any other requirements (such as test coverage).
+
+Follow this process if you'd like your work considered for inclusion in the
+project:
+
+1. [Fork](http://help.github.com/fork-a-repo/) the project, clone your fork,
+   and configure the remotes:
+
+   ```bash
+   # Clone your fork of the repo into the current directory
+   git clone https://github.com/<your-username>/normalize.css
+   # Navigate to the newly cloned directory
+   cd normalize.css
+   # Assign the original repo to a remote called "upstream"
+   git remote add upstream https://github.com/necolas/normalize.css
+   ```
+
+2. If you cloned a while ago, get the latest changes from upstream:
+
+   ```bash
+   git checkout master
+   git pull upstream master
+   ```
+
+3. Never work directly on `master`. Create a new topic branch (off the latest
+   version of `master`) to contain your feature, change, or fix:
+
+   ```bash
+   git checkout -b <topic-branch-name>
+   ```
+
+4. Commit your changes in logical chunks. Please adhere to these [git commit
+   message conventions](http://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html)
+   or your code is unlikely be merged into the main project. Use Git's
+   [interactive rebase](https://help.github.com/articles/interactive-rebase)
+   feature to tidy up your commits before making them public.
+
+   Make sure to add a test to the `test.html` file if appropriate, and test
+   your change in all supported browsers.
+
+5. Locally rebase the upstream development branch into your topic branch:
+
+   ```bash
+   git pull --rebase upstream master
+   ```
+
+6. Push your topic branch up to your fork:
+
+   ```bash
+   git push origin <topic-branch-name>
+   ```
+
+10. [Open a Pull Request](https://help.github.com/articles/using-pull-requests/)
+    with a clear title and description.
+
+    Please submit a separate pull request for any appropriate changes required
+    in the `v1` branch for legacy browsers.
+
+**IMPORTANT**: By submitting a patch, you agree to allow the project owner to
+license your work under the same license as that used by the project.
+
+
+<a name="maintainers"></a>
+## Maintainers
+
+If you have commit access, please follow this process for merging patches and
+cutting new releases.
+
+### Accepting patches
+
+1. Check that a patch is within the scope and philosophy of the project.
+2. Check that a patch has any necessary tests and a proper, descriptive commit
+   message.
+3. Test the patch locally.
+4. Do not use GitHub's merge button. Apply the patch to `master` locally
+   (either via `git am` or by checking the whole branch out). Amend minor
+   problems with the author's original commit if necessary. Then push to GitHub.
+5. If a patch should be included in `v1`, cherry-pick the commits or manually
+   apply if all else fails.
+
+### Releasing a new version
+
+1. Include all new functional changes in the CHANGELOG.
+2. Use a dedicated commit to increment the version. The version needs to be
+   added to the CHANGELOG (inc. date), and the `bower.json`, `component.json`,
+   and `normalize.css` files.
+3. The commit message must be of `v0.0.0` format.
+4. Create an annotated tag for the version: `git tag -m "v0.0.0" v0.0.0`.
+5. Push the changes and tags to GitHub: `git push --tags origin master`
+6. Checkout the `gh-pages` branch and follow the instructions in the README.

 Normalize.css is a customisable CSS file that makes browsers render all
 elements more consistently and in line with modern standards. We researched the
 differences between default browser styles in order to precisely target only
 the styles that need normalizing.
