+# Contributing to Bootstrap
+
+Looking to contribute something to Bootstrap? **Here's how you can help.**
+
+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](https://github.com/twbs/bootstrap/issues) is
+the preferred channel for [bug reports](#bug-reports), [features requests](#feature-requests)
+and [submitting pull requests](#pull-requests), but please respect the following
+restrictions:
+
+* Please **do not** use the issue tracker for personal support requests.  Stack
+  Overflow ([`bootstrap-4`](https://stackoverflow.com/questions/tagged/bootstrap-4) tag), [Slack](https://bootstrap-slack.herokuapp.com/) or [IRC](README.md#community) are better places to get help.
+
+* Please **do not** derail or troll issues. Keep the discussion on topic and
+  respect the opinions of others.
+
+* Please **do not** post comments consisting solely of "+1" or ":thumbsup:".
+  Use [GitHub's "reactions" feature](https://blog.github.com/2016-03-10-add-reactions-to-pull-requests-issues-and-comments/)
+  instead. We reserve the right to delete comments which violate this rule.
+
+* Please **do not** open issues regarding the official themes offered on <https://themes.getbootstrap.com/>.
+  Instead, please email any questions or feedback regarding those themes to `themes AT getbootstrap DOT com`.
+
+
+## Issues and labels
+
+Our bug tracker utilizes several labels to help organize and identify issues. Here's what they represent and how we use them:
+
+- `browser bug` - Issues that are reported to us, but actually are the result of a browser-specific bug. These are diagnosed with reduced test cases and result in an issue opened on that browser's own bug tracker.
+- `confirmed` - Issues that have been confirmed with a reduced test case and identify a bug in Bootstrap.
+- `css` - Issues stemming from our compiled CSS or source Sass files.
+- `docs` - Issues for improving or updating our documentation.
+- `examples` - Issues involving the example templates included in our docs.
+- `feature` - Issues asking for a new feature to be added, or an existing one to be extended or modified. New features require a minor version bump (e.g., `v3.0.0` to `v3.1.0`).
+- `build` - Issues with our build system, which is used to run all our tests, concatenate and compile source files, and more.
+- `help wanted` - Issues we need or would love help from the community to resolve.
+- `js` - Issues stemming from our compiled or source JavaScript files.
+- `meta` - Issues with the project itself or our GitHub repository.
+
+For a complete look at our labels, see the [project labels page](https://github.com/twbs/bootstrap/labels).
+
+
+## Bug reports
+
+A bug is a _demonstrable problem_ that is caused by the code in the repository.
+Good bug reports are extremely helpful, so thanks!
+
+Guidelines for bug reports:
+
+0. **Validate and lint your code** &mdash; [validate your HTML](https://html5.validator.nu/)
+   and [lint your HTML](https://github.com/twbs/bootlint) to ensure your
+   problem isn't caused by a simple error in your own code.
+
+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; ideally create a [reduced test
+   case](https://css-tricks.com/reduced-test-cases/) and a live example.
+   [This JS Bin](https://jsbin.com/lolome/edit?html,output) is a helpful template.
+
+
+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? Do other browsers show the bug differently? 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).
+
+### Reporting upstream browser bugs
+
+Sometimes bugs reported to us are actually caused by bugs in the browser(s) themselves, not bugs in Bootstrap per se.
+When feasible, we aim to report such upstream bugs to the relevant browser vendor(s), and then list them on our [Wall of Browser Bugs](https://getbootstrap.com/browser-bugs/) and [document them in MDN](https://developer.mozilla.org/en-US/docs/Web).
+
+| Vendor(s)     | Browser(s)                   | Rendering engine | Bug reporting website(s)                                                              | Notes                                                    |
+| ------------- | ---------------------------- | ---------------- | ------------------------------------------------------------------------------------- | -------------------------------------------------------- |

+| Apple         | Safari                       | WebKit           | https://bugs.webkit.org/enter_bug.cgi?product=WebKit <br> https://bugreport.apple.com/ | In Apple's bug reporter, choose "Safari" as the product. |
+| Google, Opera | Chrome, Chromium, Opera v15+ | Blink            | https://bugs.chromium.org/p/chromium/issues/list                                      | Click the "New issue" button.                            |

+
+### Issues bots
+
+[@twbs-lmvtfy](https://github.com/twbs-lmvtfy) is a Bootstrap bot that hangs out in our GitHub issue tracker and automatically checks for HTML validation errors in live examples (e.g. jsFiddles, JS Bins, Bootplys, Plunks, CodePens, etc.) posted in issue comments. If it finds any errors, it will post a follow-up comment on the issue and point out the errors. If this happens with an example you've posted, please fix the errors and post an updated live example. If you opened a bug report, please check whether the bug still occurs with your revised, valid live example. If the bug no longer occurs, it was probably due to your invalid HTML rather than something in Bootstrap and we'd appreciate it if you could close out the GitHub issue.
+
+
+## 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.
+
+
+## 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 pull request (e.g.
+implementing features, refactoring code, porting to a different language),
+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 guidelines](#code-guidelines) used throughout the
+project (indentation, accurate comments, etc.) and any other requirements
+(such as test coverage).
+
+**Do not edit `bootstrap.css`, or `bootstrap.js`
+directly!** Those files are automatically generated. You should edit the
+source files in [`/bootstrap/scss/`](https://github.com/twbs/bootstrap/tree/master/scss)
+and/or [`/bootstrap/js/`](https://github.com/twbs/bootstrap/tree/master/js) instead.
+
+Similarly, when contributing to Bootstrap's documentation, you should edit the
+documentation source files in
+[the `/bootstrap/docs/` directory of the `master` branch](https://github.com/twbs/bootstrap/tree/master/docs).
+**Do not edit the `gh-pages` branch.** That branch is generated from the
+documentation source files and is managed separately by the Bootstrap Core Team.
+
+Adhering to the following process is the best way to get your work
+included in the project:
+
+1. [Fork](https://help.github.com/articles/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>/bootstrap.git
+   # Navigate to the newly cloned directory
+   cd bootstrap
+   # Assign the original repo to a remote called "upstream"
+   git remote add upstream https://github.com/twbs/bootstrap.git
+   ```
+
+2. If you cloned a while ago, get the latest changes from upstream:
+
+   ```bash
+   git checkout master
+   git pull upstream master
+   ```
+
+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. Please adhere to these [git commit
+   message guidelines](https://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/about-git-rebase/)
+   feature to tidy up your commits before making them public.
+
+5. Locally merge (or 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>
+   ```
+
+7. [Open a Pull Request](https://help.github.com/articles/about-pull-requests/)
+    with a clear title and description against the `master` branch.
+
+**IMPORTANT**: By submitting a patch, you agree to allow the project owners to
+license your work under the terms of the [MIT License](LICENSE) (if it
+includes code changes) and under the terms of the
+[Creative Commons Attribution 3.0 Unported License](docs/LICENSE)
+(if it includes documentation changes).
+
+
+## Code guidelines
+
+### HTML
+
+[Adhere to the Code Guide.](http://codeguide.co/#html)
+
+- Use tags and elements appropriate for an HTML5 doctype (e.g., self-closing tags).
+- Use CDNs and HTTPS for third-party JS when possible. We don't use protocol-relative URLs in this case because they break when viewing the page locally via `file://`.
+- Use [WAI-ARIA](https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA) attributes in documentation examples to promote accessibility.
+
+### CSS
+
+[Adhere to the Code Guide.](http://codeguide.co/#css)
+
+- When feasible, default color palettes should comply with [WCAG color contrast guidelines](https://www.w3.org/TR/WCAG20/#visual-audio-contrast).
+- Except in rare cases, don't remove default `:focus` styles (via e.g. `outline: none;`) without providing alternative styles. See [this A11Y Project post](https://a11yproject.com/posts/never-remove-css-outlines/) for more details.
+
+### JS
+
+- No semicolons (in client-side JS)
+- 2 spaces (no tabs)
+- strict mode
+- "Attractive"
+- Don't use [jQuery event alias convenience methods](https://github.com/jquery/jquery/blob/master/src/event/alias.js) (such as `$().focus()`). Instead, use [`$().trigger(eventType, ...)`](https://api.jquery.com/trigger/) or [`$().on(eventType, ...)`](https://api.jquery.com/on/), depending on whether you're firing an event or listening for an event. (For example, `$().trigger('focus')` or `$().on('focus', function (event) { /* handle focus event */ })`) We do this to be compatible with custom builds of jQuery where the event aliases module has been excluded.
+
+### Checking coding style
+
+Run `npm run test` before committing to ensure your changes follow our coding standards.

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to making participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, nationality, personal appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable behavior and are expected to take appropriate and fair corrective action in response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community. Examples of representing a project or community include using an official project e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event. Representation of a project may be further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the project team at mdo@getbootstrap.com. The project team will review and investigate all complaints, and will respond in a way that it deems appropriate to the circumstances. The project team is obligated to maintain confidentiality with regard to the reporter of an incident. Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good faith may face temporary or permanent repercussions as determined by other members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4, available at [https://www.contributor-covenant.org/version/1/4/code-of-conduct.html][version]

+
+## Bugs and feature requests
+
+Have a bug or a feature request? Please first read the [issue guidelines](https://github.com/twbs/bootstrap/blob/master/CONTRIBUTING.md#using-the-issue-tracker) and search for existing and closed issues. If your problem or idea is not addressed yet, [please open a new issue](https://github.com/twbs/bootstrap/issues/new).
+
+
+## Documentation
+
+Bootstrap's documentation, included in this repo in the root directory, is built with [Jekyll](https://jekyllrb.com/) and publicly hosted on GitHub Pages at <https://getbootstrap.com/>. The docs may also be run locally.
+
+Documentation search is powered by [Algolia's DocSearch](https://community.algolia.com/docsearch/). Working on our search? Be sure to set `debug: true` in `site/docs/4.3/assets/js/src/search.js` file.
+
+### Running documentation locally
+
+1. Run through the [tooling setup](https://getbootstrap.com/docs/4.3/getting-started/build-tools/#tooling-setup) to install Jekyll (the site builder) and other Ruby dependencies with `bundle install`.
+2. Run `npm install` to install Node.js dependencies.
+3. Run `npm start` to compile CSS and JavaScript files, generate our docs, and watch for changes.
+4. Open `http://localhost:9001` in your browser, and voilà.
+
+Learn more about using Jekyll by reading its [documentation](https://jekyllrb.com/docs/).

+## Versioning
+
+For transparency into our release cycle and in striving to maintain backward compatibility, Bootstrap is maintained under [the Semantic Versioning guidelines](https://semver.org/). Sometimes we screw up, but we adhere to those rules whenever possible.
+
+See [the Releases section of our GitHub project](https://github.com/twbs/bootstrap/releases) for changelogs for each release version of Bootstrap. Release announcement posts on [the official Bootstrap blog](https://blog.getbootstrap.com/) contain summaries of the most noteworthy changes made in each release.

+## How does Bootstrap's test suite work?
+
+Bootstrap uses [QUnit](https://qunitjs.com/) and [Sinon](https://sinonjs.org/). Each plugin has a file dedicated to its tests in `unit/<plugin-name>.js`.
+
+* `unit/` contains the unit test files for each Bootstrap plugin.
+* `vendor/` contains third-party testing-related code (QUnit, jQuery and Sinon).
+* `visual/` contains "visual" tests which are run interactively in real browsers and require manual verification by humans.
+
+To run the unit test suite via [Karma](https://karma-runner.github.io/), run `npm run js-test`.
+
+To run the unit test suite via a real web browser, open `index.html` in the browser.
+
+
+## How do I add a new unit test?
+
+1. Locate and open the file dedicated to the plugin which you need to add tests to (`unit/<plugin-name>.js`).
+2. Review the [QUnit API Documentation](https://api.qunitjs.com/) and use the existing tests as references for how to structure your new tests.
+3. Write the necessary unit test(s) for the new or revised functionality.
+4. Run `npm run js-test` to see the results of your newly-added test(s).
+
+**Note:** Your new unit tests should fail before your changes are applied to the plugin, and should pass after your changes are applied to the plugin.
+
+## What should a unit test look like?
+
+* Each test should have a unique name clearly stating what unit is being tested.
+* Each test should test only one unit per test, although one test can include several assertions. Create multiple tests for multiple units of functionality.
+* Each test should begin with [`assert.expect`](https://api.qunitjs.com/assert/expect/) to ensure that the expected assertions are run.
+* Each test should follow the project's [JavaScript Code Guidelines](https://github.com/twbs/bootstrap/blob/master/CONTRIBUTING.md#js)
+
+## Code coverage
+
+Currently we're aiming for at least 80% test coverage for our code. To ensure your changes meet or exceed this limit, run `npm run js-compile && npm run js-test` and open the file in `js/coverage/lcov-report/index.html` to see the code coverage for each plugin. See more details when you select a plugin and ensure your change is fully covered by unit tests.
+
+### Example tests
+
+```js
+// Synchronous test
+QUnit.test('should describe the unit being tested', function (assert) {
+  assert.expect(1)
+  var templateHTML = '<div class="alert alert-danger fade show">' +
+        '<a class="close" href="#" data-dismiss="alert">×</a>' +
+        '<p><strong>Template necessary for the test.</p>' +
+        '</div>'
+  var $alert = $(templateHTML).appendTo('#qunit-fixture').bootstrapAlert()
+
+  $alert.find('.close').trigger('click')
+
+  // Make assertion
+  assert.strictEqual($alert.hasClass('show'), false, 'remove .show class on .close click')
+})
+
+// Asynchronous test
+QUnit.test('should describe the unit being tested', function (assert) {
+  assert.expect(2)
+  var done = assert.async()
+
+  var $tooltip = $('<div title="tooltip title"></div>').bootstrapTooltip()
+  var tooltipInstance = $tooltip.data('bs.tooltip')
+  var spyShow = sinon.spy(tooltipInstance, 'show')
+
+  $tooltip.appendTo('#qunit-fixture')
+    .on('shown.bs.tooltip', function () {
+      assert.ok(true, '"shown" event was fired after calling "show"')
+      assert.ok(spyShow.called, 'show called')
+      done()
+    })
+    .bootstrapTooltip('show')
