+============
+Contributing
+============
+
+Contributions are welcome, and they are greatly appreciated! Every
+little bit helps, and credit will always be given.
+
+You can contribute in many ways:
+
+Types of Contributions
+----------------------
+
+Report Bugs
+~~~~~~~~~~~
+
+Report bugs at https://github.com/pinterest/snappass/issues.
+
+If you are reporting a bug, please include:
+
+* Your operating system name and version (if relevant).
+* Any details about your local setup that might be helpful in troubleshooting.
+* If you can, provide detailed steps to reproduce the bug.
+* If you don't have steps to reproduce the bug, just note your observations in
+  as much detail as you can. Questions to start a discussion about the issue
+  are welcome.
+
+Python 3.3 Support
+~~~~~~~~~~~~~~~~~~
+
+We'd love for ``tox -e py33`` to work and would welcome anybody who can help
+make that a reality.
+
+Fix Bugs
+~~~~~~~~
+
+Look through the GitHub issues for bugs. Anything tagged with "bug"
+is open to whoever wants to implement it.
+
+Implement Features
+~~~~~~~~~~~~~~~~~~
+
+Look through the GitHub issues for features. Anything tagged with "enhancement"
+is open to whoever wants to implement it.
+
+
+Write Documentation
+~~~~~~~~~~~~~~~~~~~
+
+Snappass could always use better documentation, whether as part of the
+official docs, in docstrings, or even on the web in blog posts, articles, and
+such.
+
+Submit Feedback
+~~~~~~~~~~~~~~~
+
+The best way to send feedback is to file an issue at
+https://github.com/pinterest/snappass/issues.
+
+If you are proposing a feature:
+
+* Explain in detail how it would work.
+* Note that this project has an intentionally narrow scope.
+  Our target users are small organizations that really need a
+  quick and dirty way to exchange secrets.
+* Remember that this is a volunteer-driven project, and that contributions
+  are welcome :)
+
+
+Setting Up the Code for Local Development
+-----------------------------------------
+
+Here's how to set up `snappass` for local development.
+
+1. Fork the `snappass` repo on GitHub.
+2. Clone your fork locally::
+
+    $ git clone git@github.com:your_name_here/snappass.git
+
+3. Install your local copy into a ``virtualenv``. Assuming you have
+   ``virtualenvwrapper`` installed, this is how you set up your fork for local
+   development::
+
+    $ mkvirtualenv snappass
+    $ cd snappass/
+    $ python setup.py develop
+
+4. Create a branch for local development::
+
+    $ git checkout -b name-of-your-bugfix-or-feature
+
+   Now you can make your changes locally.
+
+5. When you're done making changes, check that your changes pass the tests and
+   flake8::
+
+    $ flake8 snappass tests
+    $ tox
+
+6. Commit your changes and push your branch to GitHub::
+
+    $ git add .
+    $ git commit -m "Your detailed description of your changes."
+    $ git push origin name-of-your-bugfix-or-feature
+
+7. Check that the test coverage hasn't dropped::
+
+    coverage run --source snappass setup.py tests
+    coverage report -m
+    coverage html
+
+8. Submit a pull request through the GitHub website.
+
+Pull Request Guidelines
+-----------------------
+
+Before you submit a pull request, check that it meets these guidelines:
+
+1. The pull request should include tests.
+2. If the pull request adds functionality, the docs should be updated. Put
+   your new functionality into a function with a docstring, and add the
+   feature to the list in README.rst.
+3. The pull request should work for Python 2.7 and ideally 3.3. Check
+   `Travis`_ and make sure that
+   the tests pass for all supported Python versions.
+

-Redis frontend to securley share passwords

+========
+SnapPass
+========
+
+.. image:: https://travis-ci.org/pinterest/snappass.png
+
+
+It's like SnapChat... for Passwords.
+
+This is a webapp that lets you share passwords securely.
+
+Let's say you have a password.  You want to give it to your coworker, Jane.
+You could email it to her, but then it's in her email, which might be backed up,
+and probably is in some storage device controlled by the NSA.
+
+You could send it to her over chat, but chances are Jane logs all her messages
+because she uses Google Talk, and Google Talk logs everything.
+
+You could write it down, but you can't find a pen, and there's way too many
+characters because your Security Person, Paul, is paranoid.
+
+So we build SnapPass.  It's not that complicated, it does one thing.  If
+Jane gets a link to the password and never looks at it, the password goes away.
+If the NSA gets a hold of the link, and they look at the password... well they
+have the password.  Also, Jane can't get the password, but now Jane knows that
+not only is someone looking in her email, they are clicking on links.
+
+Anyway, this took us very little time to write, but we figure we'd save you the
+trouble of writing it yourself, because maybe you are busy and have other things
+to do.  Enjoy.
+
+Requirements
+------------
+
+* Redis.
+* Python 2.6, 2.7 or 3.3.
+
+Installation
+------------
+
+::
+
+    $ pip install snappass
+    $ snappass
+    * Running on http://0.0.0.0:5000/
+    * Restarting with reloader
+
+Configuration
+-------------
+
+You can configure the following via environment variables.
+
+`SECRET_KEY` this should be a unique key that's used to sign key.  This should
+be kept secret.  See the `Flask Documentation`_ for more information.
+
+.. _Flask Documentation: http://flask.pocoo.org/docs/quickstart/#sessions
+
+`STATIC_URL` this should be the location of your static assets.  You might not
+need to change this.
+
+`NO_SSL` if you are not using SSL.
