-
-The Docker maintainers take security very seriously. If you discover a security issue,
-please bring it to their attention right away!
-
-Please send your report privately to [security@docker.com](mailto:security@docker.com),
-please **DO NOT** file a public issue.
-
-Security reports are greatly appreciated and we will publicly thank you for it. We also
-like to send gifts - if you're into Docker shwag make sure to let us know :)
-We currently do not offer a paid security bounty program, but are not ruling it out in
-the future.

-## Design and Cleanup Proposals
+The Docker maintainers take security seriously. If you discover a security
+issue, please bring it to their attention right away!
 
-When considering a design proposal, we are looking for:
+Please **DO NOT** file a public issue, instead send your report privately to
+[security@docker.com](mailto:security@docker.com), 
 
-* A description of the problem this design proposal solves
-* A pull request, not an issue, that modifies the documentation describing
-  the feature you are proposing, adding new documentation if necessary.
-  * Please prefix your issue with `Proposal:` in the title
-* Please review [the existing Proposals](https://github.com/docker/docker/pulls?q=is%3Aopen+is%3Apr+label%3AProposal)
-  before reporting a new one. You can always pair with someone if you both
-  have the same idea.

-When considering a cleanup task, we are looking for:
 
-* A description of the refactors made
-  * Please note any logic changes if necessary
-* A pull request with the code
-  * Please prefix your PR's title with `Cleanup:` so we can quickly address it.
-  * Your pull request must remain up to date with master, so rebase as necessary.

-## Reporting Issues
+## Reporting other issues
 
 A great way to contribute to the project is to send a detailed report when you
 encounter an issue. We always appreciate a well-written, thorough bug report,
 and will thank you for it!
 
-When reporting [issues](https://github.com/docker/docker/issues) on
-GitHub please include your host OS (Ubuntu 12.04, Fedora 19, etc).
-Please include:
+Check that [our issue database](https://github.com/docker/docker/issues)
+doesn't already include that problem or suggestion before submitting an issue.
+If you find a match, add a quick "+1" or "I have this problem too." Doing this
+helps prioritize the most common problems and requests.
+
+When reporting issues, please include your host OS (Ubuntu 12.04, Fedora 19,

 * The output of `uname -a`.
 * The output of `docker version`.
 * The output of `docker -D info`.
 
-Please also include the steps required to reproduce the problem if
-possible and applicable.  This information will help us review and fix

-## Contribution guidelines
 
-### Pull requests are always welcome
+##Quick contribution tips and guidelines
+
+This section gives the experienced contributor some tips and guidelines.
+
+###Pull requests are always welcome
+
+Not sure if that typo is worth a pull request? Found a bug and know how to fix
+it? Do it! We will appreciate it. Any significant improvement should be
+documented as [a GitHub issue](https://github.com/docker/docker/issues) before
+anybody starts working on it.
+
+We are always thrilled to receive pull requests. We do our best to process them
+quickly. If your pull request is not accepted on the first try,
+don't get discouraged! Our contributor's guide explains [the review process we
+use for simple changes](https://docs.docker.com/project/make-a-contribution/).
+
+### Design and cleanup proposals
+
+You can propose new designs for existing Docker features. You can also design
+entirely new features. We really appreciate contributors who want to refactor or
+otherwise cleanup our project. For information on making these types of
+contributions, see [the advanced contribution
+section](https://docs.docker.com/project/advanced-contributing/) in the
+contributors guide.
+
+We try hard to keep Docker lean and focused. Docker can't do everything for
+everybody. This means that we might decide against incorporating a new feature.
+However, there might be a way to implement that feature *on top of* Docker.

-process them as quickly as possible. Not sure if that typo is worth a pull
-request? Do it! We will appreciate it.
-

-
-### Discuss your design on the mailing list
-
-We recommend discussing your plans [on the mailing
-list](https://groups.google.com/forum/?fromgroups#!forum/docker-dev)
-before starting to code - especially for more ambitious contributions.
-This gives other contributors a chance to point you in the right
-direction, give feedback on your design, and maybe point out if someone
-else is working on the same thing.
-
-### Create issues...
-
-Any significant improvement should be documented as [a GitHub
-issue](https://github.com/docker/docker/issues) before anybody
-starts working on it.
-
-### ...but check for existing issues first!
-
-Please take a moment to check that an issue doesn't already exist
-documenting your bug report or improvement proposal. If it does, it
-never hurts to add a quick "+1" or "I have this problem too". This will
-help prioritize the most common problems and requests.
 
 ### Conventions
 
 Fork the repository and make changes on your fork in a feature branch:
 
-- If it's a bug fix branch, name it XXXX-something where XXXX is the number of the
-  issue.
-- If it's a feature branch, create an enhancement issue to announce your
-  intentions, and name it XXXX-something where XXXX is the number of the issue.

+	your intentions, and name it XXXX-something where XXXX is the number of the
+	issue.
 
-Submit unit tests for your changes.  Go has a great test framework built in; use
-it! Take a look at existing tests for inspiration. Run the full test suite on
-your branch before submitting a pull request.

 Write clean code. Universally formatted code promotes ease of writing, reading,

 **Git tip**: If your PR no longer merges cleanly, use `rebase master` in your
 feature branch to update your pull request rather than `merge master`.
 
-Before the pull request is merged, make sure that you squash your commits into
-logical units of work using `git rebase -i` and `git push -f`. After every
-commit the test suite should be passing. Include documentation changes in the
-same commit so that a revert would remove all traces of the feature or fix.
+Before you make a pull request, squash your commits into logical units of work
+using `git rebase -i` and `git push -f`. A logical unit of work is a consistent
+set of patches that should be reviewed together: for example, upgrading the
+version of a vendored dependency and taking advantage of its now available new
+feature constitute two separate units of work. Implementing a new function and
+calling it in another file constitute a single logical unit of work. The very
+high majory of submissions should have a single commit, so if in doubt: squash
+down to one.
+
+After every commit, [make sure the test suite passes]
+((https://docs.docker.com/project/test-and-docs/)). Include documentation
+changes in the same pull request so that a revert would remove all traces of
+the feature or fix.
 
-Commits that fix or close an issue should include a reference like
-`Closes #XXXX` or `Fixes #XXXX`, which will automatically close the
-issue when merged.

 A change requires LGTMs from an absolute majority of the maintainers of each

 needs an absolute majority from the maintainers of `docs/` AND, separately, an
 absolute majority of the maintainers of `registry/`.

+## Removing files from the docs.docker.com site

+Sometimes it becomes necessary to remove files from the historical published documentation.
+The most reliable way to do this is to do it directly using `aws s3` commands running in a
+docs container:

+Start the docs container like `make docs-shell`, but bind mount in your `awsconfig`:
