+# Chai Contribution Guidelines
+
+We like to encourage you to contribute to the Chai.js repository. This should be as easy as possible for you but there are a few things to consider when contributing. The following guidelines for contribution should be followed if you want to submit a pull request or open an issue.
+
+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.
+

+
+<a name="tldr"></a>
+## TLDR;
+
+- Creating an Issue or Pull Request requires a [GitHub](http://github.com) account.
+- Issue reports should be **clear**, **concise** and **reproducible**. Check to see if your issue has already been resolved in the [master]() branch or already reported in Chai's [GitHub Issue Tracker](https://github.com/chaijs/chai/issues).
+- Pull Requests must adhere to strict [coding style guidelines](https://github.com/chaijs/chai/wiki/Chai-Coding-Style-Guide).
+- In general, avoid submitting PRs for new Assertions without asking core contributors first. More than likely it would be better implemented as a plugin.
+- Additional support is available via the [Google Group](http://groups.google.com/group/chaijs) or on irc.freenode.net#chaijs.
+- **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.

+## Contributing
+
+The issue tracker is the preferred channel for [bug reports](#bugs),
+[feature 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 (use
+  [Google Group](https://groups.google.com/forum/#!forum/chaijs) or IRC).
+* 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.
+
+Guidelines for bug reports:
+
+1. **Use the GitHub issue search** &mdash; check if the issue has already been reported.
+2. **Check if the issue has been fixed** &mdash; try to reproduce it using the latest `master` or development branch in the repository.
+3. **Isolate the problem** &mdash; create a test case to demonstrate your issue. Provide either a repo, gist, or code sample to demonstrate you problem.
+
+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/or Node.js versions 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 OR
+> ```js
+> expect(a).to.equal('a');
+> // code sample
+> ```
+>
+> 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.
+
+Furthermore, since Chai.js has a [robust plugin API](http://chaijs.com/guide/plugins/), we encourage you to publish **new Assertions** as plugins. If your feature is an enhancement to an **existing Assertion**, please propose your changes as an issue prior to opening a pull request. If the core Chai.js contributors feel your plugin would be better suited as a core assertion, they will invite you to open a PR in [chaijs/chai](https://github.com/chaijs/chai).
+
+<a name="pull-requests"></a>
+### Pull Requests
+
+- PRs for new core-assertions are advised against.
+- PRs for core-assertion bug fixes are always welcome.
+- PRs for enhancing the interfaces are always welcome.
+- PRs that increase test coverage are always welcome.
+- PRs are scrutinized for coding-style.
+
+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 pull request (e.g. implementing features, refactoring code), 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 (indentation, accurate comments, etc.) and any other requirements (such as test coverage). Please review the [Chai.js Coding Style Guide](https://github.com/chaijs/chai/wiki/Chai-Coding-Style-Guide).
+
+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>/<repo-name>
+# Navigate to the newly cloned directory
+cd <repo-name>
+# Assign the original repo to a remote called "upstream"
+git remote add upstream https://github.com/<upstream-owner>/<repo-name>
+```
+
+2. If you cloned a while ago, get the latest changes from upstream:
+
+```bash
+git checkout <dev-branch>
+git pull upstream <dev-branch>
+```
+
+3. Create a new topic branch (off the main project development branch) to contain your feature, change, or fix:
+
+```bash
+git checkout -b <topic-branch-name>
+```
+
+4. Commit your changes in logical chunks. Use Git's [interactive rebase](https://help.github.com/articles/interactive-rebase) feature to tidy up your commits before making them public.
+
+5. Run you code to make sure it works. If you're still having problems please try to run `make clean` and then test your code again.
+
+```bash
+npm test
+# when finished running tests...
+git checkout chai.js
+```
+
+6. Locally merge (or rebase) the upstream development branch into your topic branch:
+
+```bash
+git pull [--rebase] upstream <dev-branch>
+```
+
+7. Push your topic branch up to your fork:
+
+```bash
+git push origin <topic-branch-name>
+```
+
+8. [Open a Pull Request](https://help.github.com/articles/using-pull-requests/) with a clear title and description.
+
+**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="releasing"></a>
+## Releasing
+
+Releases can be **prepared** by anyone with access to the code.
+
+Simply run `make release-major`, `make release-minor`, or `make-release-patch`
+and it will automatically do the following:
+
+ - Build chai.js
+ - Bump the version numbers across the project
+ - Make a commit within git
+
+All you need to do is push the commit up and make a pull request, one of the core contributors will merge it and publish a release.
+
+### Publishing a Release
+
+Anyone who is a core contributor (see the [Core Contributors Heading in the Readme](https://github.com/chaijs/chai#core-contributors)) can publish a release:
+
+1. Go to the [Releases page on Github](https://github.com/chaijs/chai/releases)
+2. Hit "Draft a new release" (if you can't see this, you're not a core contributor!)
+3. Write human-friendly Release Notes based on changelog.
+  - The release title is "x.x.x / YYYY-MM-DD" (where x.x.x is the version number)
+  - If breaking changes, write migration tutorial(s) and reasoning.
+  - Callouts for community contributions (PRs) with links to PR and contributing user.
+  - Callouts for other fixes made by core contributors with links to issue.
+4. Hit "Save Draft" and get other core contributors to check your work, or alternatively hit "Publish release"
+5. That's it!

+
+## What is Chai?
+
+Chai is an _assertion library_, similar to Node's built-in `assert`. It makes testing much easier by giving you lots of assertions you can run against your code.
+
+## Installation
+
+### Node.js
+
+`chai` is available on [npm](http://npmjs.org). To install it, type:
+
+    $ npm install --save-dev chai
+
+### Browsers
+
+You can also use it within the browser; install via npm and use the `chai.js` file found within the download. For example:
+
+```html
+<script src="./node_modules/chai/chai.js"></script>
+```
+
+## Usage
+
+Import the library in your code, and then pick one of the styles you'd like to use - either `assert`, `expect` or `should`:
+
+```js
+import { assert } from 'chai';  // Using Assert style
+import { expect } from 'chai';  // Using Expect style
+import { should } from 'chai';  // Using Should style
+```
+
+### Register the chai testing style globally
+
+```js
+import 'chai/register-assert';  // Using Assert style
+import 'chai/register-expect';  // Using Expect style
+import 'chai/register-should';  // Using Should style
+```
+
+### Import assertion styles as local variables
+
+```js
+import { assert } from 'chai';  // Using Assert style
+import { expect } from 'chai';  // Using Expect style
+import { should } from 'chai';  // Using Should style
+should();  // Modifies `Object.prototype`
+
+import { expect, use } from 'chai';  // Creates local variables `expect` and `use`; useful for plugin use
+```
+
+### Usage with Mocha
+
+```bash
+mocha spec.js --require chai/register-assert.js  # Using Assert style
+mocha spec.js --require chai/register-expect.js  # Using Expect style
+mocha spec.js --require chai/register-should.js  # Using Should style
+```
+
+[Read more about these styles in our docs](http://chaijs.com/guide/styles/).
+
+## Plugins
+
+Chai offers a robust Plugin architecture for extending Chai's assertions and interfaces.
+
+- Need a plugin? View the [official plugin list](http://chaijs.com/plugins).
+- Want to build a plugin? Read the [plugin api documentation](http://chaijs.com/guide/plugins/).
+- Have a plugin and want it listed? Simply add the following keywords to your package.json:
+  -  `chai-plugin`
+  -  `browser` if your plugin works in the browser as well as Node.js
+  -  `browser-only` if your plugin does not work with Node.js

+## 1.10.0 / 2014-11-10
+
+The following changes are required if you are upgrading from the previous version:
+
+- **Users:**
+  - No changes required
+- **Plugin Developers:**
+  - Review `addChainableNoop` notes below.
+- **Core Contributors:**
+  - Refresh `node_modules` folder for updated dependencies.
+
+### Noop Function for Terminating Assertion Properties
+
+The following assertions can now also be used in the function-call form:
+
+* ok
+* true
+* false
+* null
+* undefined
+* exist
+* empty
+* arguments
+* Arguments
+
+The above list of assertions are property getters that assert immediately on
+access. Because of that, they were written to be used by terminating the assertion
+chain with a property access.
+
+```js
+expect(true).to.be.true;
+foo.should.be.ok;
+```
+
+This syntax is definitely aesthetically pleasing but, if you are linting your
+test code, your linter will complain with an error something like "Expected an
+assignment or function call and instead saw an expression." Since the linter
+doesn't know about the property getter it assumes this line has no side-effects,
+and throws a warning in case you made a mistake.
+
+Squelching these errors is not a good solution as test code is getting to be
+just as important as, if not more than, production code. Catching syntactical
+errors in tests using static analysis is a great tool to help make sure that your
+tests are well-defined and free of typos.
+
+A better option was to provide a function-call form for these assertions so that
+the code's intent is more clear and the linters stop complaining about something
+looking off. This form is added in addition to the existing property access form
+and does not impact existing test code.
+
+```js
+expect(true).to.be.true();
+foo.should.be.ok();
+```
+
+These forms can also be mixed in any way, these are all functionally identical:
+
+```js
+expect(true).to.be.true.and.not.false();
+expect(true).to.be.true().and.not.false;
+expect(true).to.be.true.and.not.false;
+```
+
+#### Plugin Authors
+
+If you would like to provide this function-call form for your terminating assertion
+properties, there is a new function to register these types of asserts. Instead
+of using `addProperty` to register terminating assertions, simply use `addChainableNoop`
+instead; the arguments to both are identical. The latter will make the assertion
+available in both the attribute and function-call forms and should have no impact
+on existing users of your plugin.

+## 1.9.1 / 2014-03-19
+
+The following changes are required if you are upgrading from the previous version:
+
+- **Users:**
+  - Migrate configuration options to new interface. (see notes)
+- **Plugin Developers:**
+  - No changes required
+- **Core Contributors:**
+  - Refresh `node_modules` folder for updated dependencies.
+
+### Configuration
+
+There have been requests for changes and additions to the configuration mechanisms
+and their impact in the Chai architecture. As such, we have decoupled the
+configuration from the `Assertion` constructor. This not only allows for centralized
+configuration, but will allow us to shift the responsibility from the `Assertion`
+constructor to the `assert` interface in future releases.
+
+These changes have been implemented in a non-breaking way, but a depretiation
+warning will be presented to users until they migrate. The old config method will
+be removed in either `v1.11.0` or `v2.0.0`, whichever comes first.
+
+#### Quick Migration
+
+```js
+// change this:
+chai.Assertion.includeStack = true;
+chai.Assertion.showDiff = false;
+
+// ... to this:
+chai.config.includeStack = true;
+chai.config.showDiff = false;
+```
+
+#### All Config Options
+
+##### config.includeStack
+
+- **@param** _{Boolean}_
+- **@default** `false`
+
+User configurable property, influences whether stack trace is included in
+Assertion error message. Default of `false` suppresses stack trace in the error
+message.
+
+##### config.showDiff
+
+- **@param** _{Boolean}_
+- **@default** `true`
+
+User configurable property, influences whether or not the `showDiff` flag
+should be included in the thrown AssertionErrors. `false` will always be `false`;
+`true` will be true when the assertion has requested a diff be shown.
+
+##### config.truncateThreshold **(NEW)**
+
+- **@param** _{Number}_
+- **@default** `40`
+
+User configurable property, sets length threshold for actual and expected values
+in assertion errors. If this threshold is exceeded, the value is truncated.
+
+Set it to zero if you want to disable truncating altogether.
+
+```js
+chai.config.truncateThreshold = 0; // disable truncating
+```

+
+## 1.8.0 / 2013-09-18
+
+The following changes are required if you are upgrading from the previous version:
+
+- **Users:**
+  - See `deep.equal` notes.
+- **Plugin Developers:**
+  - No changes required
+- **Core Contributors:**
+  - Refresh `node_modules` folder for updated dependencies.
+
+### Deep Equals
+
+This version of Chai focused on a overhaul to the deep equal utility. The code for this
+tool has been removed from the core lib and can now be found at:
+[chai / deep-eql](https://github.com/chaijs/deep-eql). As stated in previous releases,
+this is part of a larger initiative to provide transparency, independent testing, and coverage for
+some of the more complicated internal tools.
+
+For the most part `.deep.equal` will behave the same as it has. However, in order to provide a
+consistent ruleset across all types being tested, the following changes have been made and _might_
+require changes to your tests.
+
+**1.** Strict equality for non-traversable nodes according to [egal](http://wiki.ecmascript.org/doku.php?id=harmony:egal).
+
+_Previously:_ Non-traversable equal via `===`.
+
+```js
+expect(NaN).to.deep.equal(NaN);
+expect(-0).to.not.deep.equal(+0);
+```
+
+**2.** Arguments are not Arrays (and all types must be equal):
+
+_Previously:_ Some crazy nonsense that led to empty arrays deep equaling empty objects deep equaling dates.
+
+```js
+expect(arguments).to.not.deep.equal([]);
+expect(Array.prototype.slice.call(arguments)).to.deep.equal([]);
+```
+

+- [#192](https://github.com/chaijs/chai/issues/192) empty object is eql to a Date object
+- [#194](https://github.com/chaijs/chai/issues/194) refactor deep-equal utility
+
+### CI and Browser Testing
+
+Chai now runs the browser CI suite using [Karma](http://karma-runner.github.io/) directed at
+[SauceLabs](https://saucelabs.com/). This means we get to know where our browser support stands...
+and we get a cool badge:
+
+[![Selenium Test Status](https://saucelabs.com/browser-matrix/logicalparadox.svg)](https://saucelabs.com/u/logicalparadox)
+
+Look for the list of browsers/versions to expand over the coming releases.

+## 1.7.2 / 2013-06-27
+
+The following changes are required if you are upgrading from the previous version:
+
+- **Users:**
+  - No changes required.
+- **Plugin Developers:**
+  - No changes required
+- **Core Contributors:**
+  - Refresh `node_modules` folder for updated dependencies.
+
+### Coverage Reporting
+
+Coverage reporting has always been available for core-developers but the data has never been published
+for our end users. In our ongoing effort to improve accountability this data will now be published via
+the [coveralls.io](https://coveralls.io/) service. A badge has been added to the README and the full report
+can be viewed online at the [chai coveralls project](https://coveralls.io/r/chaijs/chai). Furthermore, PRs
+will receive automated messages indicating how their PR impacts test coverage. This service is tied to TravisCI.
+
+### Other Fixes
+
+- [#175](https://github.com/chaijs/chai/issues/175) Add `bower.json`. (Fix ignore all)

+
+### Official Bower Support
+
+Support has been added for the Bower Package Manager ([bower.io])(http://bower.io/). Though
+Chai could be installed via Bower in the past, this update adds official support via the `bower.json`
+specification file.
+
+- [#175](https://github.com/chaijs/chai/issues/175) Add `bower.json`.
+
+## 1.7.0 / 2013-06-17
+
+The following changes are required if you are upgrading from the previous version:
+
+- **Users:**
+  - No changes required.
+- **Plugin Developers:**
+  - Review AssertionError update notice.
+- **Core Contributors:**
+  - Refresh `node_modules` folder for updated dependencies.
+
+### AssertionError Update Notice
+
+Chai now uses [chaijs/assertion-error](https://github.com/chaijs/assertion-error) instead an internal
+constructor. This will allow for further iteration/experimentation of the AssertionError constructor
+independant of Chai. Future plans include stack parsing for callsite support.
+
+This update constructor has a different constructor param signature that conforms more with the standard
+`Error` object. If your plugin throws and `AssertionError` directly you will need to update your plugin
+with the new signature.
+
+```js
+var AssertionError = require('chai').AssertionError;
+
+/**
+ * previous
+ *
+ * @param {Object} options
+ */
+
+throw new AssertionError({
+    message: 'An assertion error occurred'
+  , actual: actual
+  , expect: expect
+  , startStackFunction: arguments.callee
+  , showStack: true
+});
+
+/**
+ * new
+ *
+ * @param {String} message
+ * @param {Object} options
+ * @param {Function} start stack function
+ */
+
+throw new AssertionError('An assertion error occurred', {
+    actual: actual
+  , expect: expect
+  , showStack: true
+}, arguments.callee);
+
+// other signatures
+throw new AssertionError('An assertion error occurred');
+throw new AssertionError('An assertion error occurred', null, arguments.callee);
+```
+
+#### External Dependencies
+
+This is the first non-developement dependency for Chai. As Chai continues to evolve we will begin adding
+more; the next will likely be improved type detection and deep equality. With Chai's userbase continually growing
+there is an higher need for accountability and documentation. External dependencies will allow us to iterate and
+test on features independent from our interfaces.
+
+Note: The browser packaged version `chai.js` will ALWAYS contain all dependencies needed to run Chai.

+
+### New Assertions
+
+#### Array Members Inclusion
+
+Asserts that the target is a superset of `set`, or that the target and `set` have the same members.
+Order is not taken into account. Thanks to [@NickHeiner](https://github.com/NickHeiner) for the contribution.
+
+```js
+// (expect/should) full set
+expect([4, 2]).to.have.members([2, 4]);
+expect([5, 2]).to.not.have.members([5, 2, 1]);
+
+// (expect/should) inclusion
+expect([1, 2, 3]).to.include.members([3, 2]);
+expect([1, 2, 3]).to.not.include.members([3, 2, 8]);
+
+// (assert) full set
+assert.sameMembers([ 1, 2, 3 ], [ 2, 1, 3 ], 'same members');
+
+// (assert) inclusion
+assert.includeMembers([ 1, 2, 3 ], [ 2, 1 ], 'include members');
+
+```
+
+#### Non-inclusion for Assert Interface
+
+Most `assert` functions have a negative version, like `instanceOf()` has a corresponding `notInstaceOf()`.
+However `include()` did not have a corresponding `notInclude()`. This has been added.
+
+```js
+assert.notInclude([ 1, 2, 3 ], 8);
+assert.notInclude('foobar', 'baz');
+```

+### Other Bug Fixes
+
+- Improve type detection of `.a()`/`.an()` to work in cross-browser scenarios.
+- [#116](https://github.com/chaijs/chai/issues/116): `.throw()` has cleaner display of errors when WebKit browsers.

+
+
+### Usage Updates
+
+#### For Users
+
+**1. Component Support:** Chai now included the proper configuration to be installed as a
+[component](https://github.com/component/component). Component users are encouraged to consult
+[chaijs.com](http://chaijs.com) for the latest version number as using the master branch
+does not gaurantee stability.
+
+```js
+// relevant component.json
+  devDependencies: {
+    "chaijs/chai": "1.5.0"
+  }
+```
+
+Alternatively, bleeding-edge is available:
+
+    $ component install chaijs/chai
+
+**2. Configurable showDiff:** Some test runners (such as [mocha](http://visionmedia.github.com/mocha/))
+include support for showing the diff of strings and objects when an equality error occurs. Chai has
+already included support for this, however some users may not prefer this display behavior. To revert to
+no diff display, the following configuration is available:
+
+```js
+chai.Assertion.showDiff = false; // diff output disabled
+chai.Assertion.showDiff = true; // default, diff output enabled
+```
+
+#### For Plugin Developers
+
+**1. New Utility - type**: The new utility `.type()` is available as a better implementation of `typeof`
+that can be used cross-browser. It handles the inconsistencies of Array, `null`, and `undefined` detection.
+
+- **@param** _{Mixed}_ object to detect type of
+- **@return** _{String}_ object type
+
+```js
+chai.use(function (c, utils) {
+  // some examples
+  utils.type({}); // 'object'
+  utils.type(null); // `null'
+  utils.type(undefined); // `undefined`
+  utils.type([]); // `array`
+});
+```
+
+#### For Core Contributors
+
+**1. Browser Testing**: Browser testing of the `./chai.js` file is now available in the command line
+via PhantomJS. `make test` and Travis-CI will now also rebuild and test `./chai.js`. Consequently, all
+pull requests will now be browser tested in this way.
+
+_Note: Contributors opening pull requests should still NOT include the browser build._
+
+**2. SauceLabs Testing**: Early SauceLab support has been enabled with the file `./support/mocha-cloud.js`.
+Those interested in trying it out should create a free [Open Sauce](https://saucelabs.com/signup/plan) account
+and include their credentials in `./test/auth/sauce.json`.

+   * - `object`: This flag contains the target of the assertion. For example, in

+   *
+   * - `message`: This flag contains an optional custom error message to be
+   * prepended to the error message that's generated by the assertion when it
+   * fails.
+   *
+   * - `ssfi`: This flag stands for "start stack function indicator". It
+   * contains a function reference that serves as the starting point for
+   * removing frames from the stack trace of the error that's created by the
+   * assertion when it fails. The goal is to provide a cleaner stack trace to
+   * end users by removing Chai's internal functions. Note that it only works
+   * in environments that support `Error.captureStackTrace`, and only when
+   * `Chai.config.includeStack` hasn't been set to `false`.
+   *
+   * - `lockSsfi`: This flag controls whether or not the given `ssfi` flag
+   * should retain its current value, even as assertions are chained off of
+   * this object. This is usually set to `true` when creating a new assertion
+   * from within another assertion. It's also temporarily set to `true` before
+   * an overwritten assertion gets called by the overwriting assertion.
+   *
+   * - `eql`: This flag contains the deepEqual function to be used by the assertion.
