+# A test-driven JS assessment
+
+[![Join the chat at https://gitter.im/rmurphey/js-assessment](https://badges.gitter.im/Join%20Chat.svg)](https://gitter.im/rmurphey/js-assessment?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)
+
+This repo includes a set of tests that can be used to assess the skills of
+a candidate for a JavaScript position, or to improve one's own skills.
+
+## I want to work on the tests; what do I do?
+To use the tests, you will need to install Node -- you can do this via the
+[download page](https://nodejs.org/download/) or using
+[Homebrew](http://mxcl.github.com/homebrew/) if you are on a Mac.
+
+Note that on Windows, there are some reports that you will need to restart
+after installing Node - see #12.
+
+You can clone or download this repo. Once you have done so, from the root
+directory of the repo, run:
+
+    npm install
+    npm start
+
+You can then view the tests in your browser at
+[http://localhost:4444](http://localhost:4444).
+
+When you visit that page, all of the tests should be failing; your job is to
+get the tests to pass. To do this, you'll need to refer to the tests in the
+files in the `tests/app` directory, and edit the files in the `app/` directory.
+Once you update a test, you can reload the test page in the browser to see
+whether it worked.
+
+You can also run (most of) the tests on the command line:
+
+    npm test
+
+The command line runner is a work in progress; contributions welcome :)
+
+You can also develop with live-reload and grunt-watch if that's your thing:
+
+    npm install -g grunt-cli
+    npm install
+    grunt develop
+
+## I need help!
+
+There may be friendly folks willing to help you in \#js-assessment or
+\#jshotline on freenode IRC.
+
+## I want to contribute tests; what do I do?
+
+Submit a pull request! The tests are currently loosely organized by topic, so
+you should do your best to add tests to the appropriate file in `tests/app`, or
+create a new file there if you don't see an appropriate one. If you do create
+a new file, make sure to add it to `tests/runner.js`, and to add a stub for the
+solution to the corresponding file in `app/`. Finally, it would be great if you
+could update the [answers](https://github.com/rmurphey/js-assessment-answers)
+as well.
+
+Any substantial contributions will be duly credited in the readme, as well as
+of course in the git commit log.
+
+### Data-driven tests
+
+If your tests need data that can be fetched via XHR, stick a `.json` file in
+the `data` directory; you can access it at `/data/<filename>.json`.
+
+### Available dependencies
+
+The repo includes jQuery, Backbone, and Underscore. Do take advantage of these
+libraries when writing your solutions!
+
+## I want to see the answers!
+
+First, bear in mind that looking up the answers is going to teach you a whole
+lot less than you'll learn by working on the tests, even if you occasionally get
+stuck. I'd recommend only looking at the answers once you have the tests
+passing, to see if there's another way you could have approached the
+problem. When you're ready to look at the answers, you can find them
+[here](https://github.com/rmurphey/js-assessment-answers); I'll do my best to
+keep them up to date.
+
+## I hate \<some technology you've chosen\>
+
+This repo uses [Mocha](http://visionmedia.github.com/mocha/) and
+[Chai](http://chaijs.com/) for the tests themselves. It uses the BDD style for authoring tests.
+If this doesn't suit you, please fork away, or, better, submit a pull request that lets
+this be more flexible than it currently is.
+
+# Todos
+
+There are a number of things that would make this project better; check out the
+[issues](https://github.com/rmurphey/js-assessment/issues) for details, pull
+requests welcome!
