+# 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-5`](https://stackoverflow.com/questions/tagged/bootstrap-5) tag), [our GitHub Discussions](https://github.com/twbs/bootstrap/discussions) 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 .
+ Instead, please email any questions or feedback regarding those themes to `themes AT getbootstrap DOT com`.
+
+
+## Issues assignment
+
+The core team will be looking at the open issues, analyze them, and provide guidance on how to proceed. **Issues won't be assigned to anyone outside the core team.** However, contributors are welcome to participate in the discussion and provide their input on how to best solve the issue, and even submit a PR if they want to. Please wait that the issue is ready to be worked on before submitting a PR, we don't want to waste your time.
+
+Please keep in mind that the core team is small, has limited resources and that we are not always able to respond immediately. We will try to provide feedback as soon as possible, but please be patient. If you don't get a response immediately, it doesn't mean that we are ignoring you or that we don't care about your issue or PR. We will get back to you as soon as we can.
+
+
+## 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 your HTML](https://html5.validator.nu/)** to ensure your
+ problem isn't caused by a simple error in your own code.
+
+1. **Use the GitHub issue search** — check if the issue has already been
+ reported.
+
+2. **Check if the issue has been fixed** — try to reproduce it using the
+ latest `main` (or `v4-dev` branch if the issue is about v4) in the repository.
+
+3. **Isolate the problem** — ideally create a [reduced test
+ case](https://css-tricks.com/reduced-test-cases/) and a live example.
+ These [v4 CodePen](https://codepen.io/team/bootstrap/pen/yLabNQL) and [v5 CodePen](https://codepen.io/team/bootstrap/pen/qBamdLj) are helpful templates.
+
+
+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.
+>
+> `` - 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.
+
+| Vendor(s) | Browser(s) | Rendering engine | Bug reporting website(s) | Notes |
+| ------------- | ---------------------------- | ---------------- | ------------------------------------------------------ | -------------------------------------------------------- |
+| Mozilla | Firefox | Gecko | | "Core" is normally the right product option to choose. |
+| Apple | Safari | WebKit | | In Apple's bug reporter, choose "Safari" as the product. |
+| Google, Opera | Chrome, Chromium, Opera v15+ | Blink | | Click the "New issue" button. |
+| Microsoft | Edge | Blink | | Go to "Help > Send Feedback" from the browser |
+
+
+## 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. For trivial
+things, or things that don't require a lot of your time, you can go ahead and
+make a PR.
+
+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`, and do not commit
+any dist files (`dist/` or `js/dist`).** Those files are automatically generated by our build tools. You should
+edit the source files in [`/bootstrap/scss/`](https://github.com/twbs/bootstrap/tree/main/scss)
+and/or [`/bootstrap/js/src/`](https://github.com/twbs/bootstrap/tree/main/js/src) instead.
+
+Similarly, when contributing to Bootstrap's documentation, you should edit the
+documentation source files in
+[the `/bootstrap/site/content/docs/` directory of the `main` branch](https://github.com/twbs/bootstrap/tree/main/site/content/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//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 main
+ git pull upstream main
+ ```
+
+3. Create a new topic branch (off the main project development branch) to
+ contain your feature, change, or fix:
+
+ ```bash
+ git checkout -b
+ ```
+
+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 main
+ ```
+
+6. Push your topic branch up to your fork:
+
+ ```bash
+ git push origin
+ ```
+
+7. [Open a Pull Request](https://help.github.com/articles/about-pull-requests/)
+ with a clear title and description against the `main` 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](https://creativecommons.org/licenses/by/3.0/)
+(if it includes documentation changes).
+
+
+## Code guidelines
+
+### HTML
+
+[Adhere to the Code Guide.](https://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.](https://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://www.a11yproject.com/posts/2013-01-25-never-remove-css-outlines/) for more details.
+
+### JS
+
+- No semicolons (in client-side JS)
+- 2 spaces (no tabs)
+- strict mode
+- "Attractive"
+
+### Checking coding style
+
+Run `npm run test` before committing to ensure your changes follow our coding standards.

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, caste, color, religion, or sexual
+identity and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+- Demonstrating empathy and kindness toward other people
+- Being respectful of differing opinions, viewpoints, and experiences
+- Giving and gracefully accepting constructive feedback
+- Accepting responsibility and apologizing to those affected by our mistakes,
+ and learning from the experience
+- Focusing on what is best not just for us as individuals, but for the overall
+ community
+
+Examples of unacceptable behavior include:
+
+- The use of sexualized language or imagery, and sexual attention or advances of
+ any kind
+- Trolling, insulting or derogatory comments, and personal or political attacks
+- Public or private harassment
+- Publishing others' private information, such as a physical or email address,
+ without their explicit permission
+- Other conduct which could reasonably be considered inappropriate in a
+ professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders 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, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official e-mail address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement at
+mdo@getbootstrap.com.
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series of
+actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or permanent
+ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior, harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within the
+community.
