-        Make it obvious to understand and reproduce this bug. Ideally, we should be able to understand it without running any code.
+        Before filing your issue, ask yourself:
+        - Is this clearly a Docusaurus defect?
+        - Do I have basic ideas about where it goes wrong? (For example, if there are stack traces, are they pointing to one file?)
+        - Could it be because of my own mistakes?
+
+        **The GitHub issue tracker is not a support forum**. If you are not sure whether it could be your mistakes, ask in the [Discord server](https://discord.gg/docusaurus) or [GitHub discussions](https://github.com/facebook/docusaurus/discussions) first. The quickest way to verify whether it's a Docusaurus defect is through a **reproduction**, starting with a fresh installation and making changes until the bug is reproduced.

 - Look through the [open issues](https://github.com/facebook/docusaurus/issues). Provide workarounds, ask for clarification, or suggest labels. Help [triage issues](#triaging-issues-and-pull-requests).
-- If you find an issue you would like to fix, [open a pull request](#your-first-pull-request). Issues tagged as [_Good first issue_](https://github.com/facebook/docusaurus/labels/Good%20first%20issue) are a good place to get started.

 Docusaurus has one primary branch `main` and we use feature branches with deploy previews to deliver new features with pull requests.
 
-## Proposing a Change
-
-If you would like to request a new feature or enhancement but are not yet thinking about opening a pull request, you can also file an issue with the [feature template](https://github.com/facebook/docusaurus/issues/new?assignees=&labels=feature%2Cneeds+triage&template=feature.yml).
-
-If you intend to change the public API (e.g., something in `siteConfig.js`) or make any non-trivial changes to the implementation, we recommend filing an issue with the [proposal template](https://github.com/facebook/docusaurus/issues/new?assignees=&labels=proposal%2Cneeds+triage&template=proposal.yml). This lets us reach an agreement on your proposal before you put significant effort into it. These types of issues should be rare.
-
-If you're only fixing a bug, it's fine to submit a pull request right away but we still recommend [filing an issue](https://github.com/facebook/docusaurus/issues/new?assignees=&labels=bug%2Cneeds+triage&template=bug.yml) detailing what you're fixing. This is helpful in case we don't accept that specific fix but want to keep track of the issue.

-### Reporting New Issues
+## Issues
 
 When [opening a new issue](https://github.com/facebook/docusaurus/issues/new/choose), always make sure to fill out the issue template. **This step is very important!** Not doing so may result in your issue not being managed in a timely fashion. Don't take this personally if this happens, and feel free to open a new issue once you've gathered all the information required by the template.
 
+**Please don't use the GitHub issue tracker for questions.** If you have questions about using Docusaurus, use any of our [support channels](https://docusaurus.io/community/support), and we will do our best to answer your questions.
+
+### Bugs
+
+We use [GitHub Issues](https://github.com/facebook/docusaurus/issues) for our public bugs. If you would like to report a problem, take a look around and see if someone already opened an issue about it. If you are certain this is a new, unreported bug, you can submit a [bug report](https://github.com/facebook/docusaurus/issues/new?assignees=&labels=bug%2Cstatus%3A+needs+triage&template=bug.yml).
+
 - **One issue, one bug:** Please report a single bug per issue.
 - **Provide reproduction steps:** List all the steps necessary to reproduce the issue. The person reading your bug report should be able to follow these steps to reproduce your issue with minimal effort.

+### Claiming issues
 
 We have a list of [beginner-friendly issues](https://github.com/facebook/docusaurus/labels/good%20first%20issue) to help you get your feet wet in the Docusaurus codebase and familiar with our contribution process. This is a great place to get started.
 
-### Versioned Docs
+Apart from the `good first issue`, the following labels are also worth looking at:
 
-If you only want to make content changes you just need to be aware of versioned docs.
+- [`help wanted`](https://github.com/facebook/docusaurus/labels/help%20wanted): if you have specific knowledge in one domain, working on these issues can make your expertise shine.
+- [`status: accepting pr`](https://github.com/facebook/docusaurus/labels/status%3A%20accepting%20pr): community contributors can feel free to claim any of these.
 
-- `website/docs` - The files here are responsible for the "next" version at https://docusaurus.io/docs/next/installation.
-- `website/versioned_docs/version-X.Y.Z` - These are the docs for the X.Y.Z version at https://docusaurus.io/docs/X.Y.Z/installation.
+If you want to work on any of these issues, just drop a message saying "I'd like to work on this", and we will assign the issue to you and update the issue's status as "claimed". **You are expected to send a pull request within seven days** after that, so we can still delegate the issue to someone else if you are unavailable.
 
-To make a fix to the published versions you must edit the corresponding markdown file in both folders. If you only made changes in `docs`, be sure to be viewing the `next` version to see the updates (ensure there's `next` in the URL).
+Alternatively, when opening an issue, you can also click the "self service" checkbox to indicate that you'd like to work on the issue yourself, which will also make us see the issue as "claimed".
 
-> Do not edit the auto-generated files within `versioned_docs/` or `versioned_sidebars/` unless you are sure it is necessary. For example, information about new features should not be documented in versioned docs. Edits made to older versions will not be propagated to newer versions of the docs.

-#### Test Plan
+We have a lot of integration systems that run automated tests to guard against mistakes. The maintainers will also review your code and fix obvious issues for you. These systems' duty is to make you worry as little about the chores as possible. Your code contributions are more important than sticking to any procedures, although completing the checklist will surely save everyone's time.
 
-A good test plan has the exact commands you ran and their output and provides screenshots or videos if the pull request changes UI. If you've changed APIs, update the documentation.

-## License
+Tests are integrated into our continuous integration system, so you don't always need to run local tests. However, for significant code changes, it saves both your and the maintainers' time if you can do exhaustive tests locally first to make sure your PR is in good shape. There are many types of tests:
 
-By contributing to Docusaurus, you agree that your contributions will be licensed under its MIT license.
+- **Build and typecheck.** We use TypeScript in our codebase, which can make sure your code is consistent and catches some obvious mistakes early.
+- **Unit tests.** We use [Jest](https://jestjs.io/) for unit tests of API endpoints' behavior. You can run `yarn test` in the root directory to run all tests, or `yarn test path/to/your/file.test.ts` to run a specific test.
+- **Dogfooding.** Our website itself covers all kinds of potential configuration cases and we even have a dedicated [tests area](https://docusaurus.io/tests). Don't be afraid to update our website's configuration in your PR—it can help the maintainers preview the effects. We can decide if the website change should be kept when merging and deploying for production.
+- **E2E tests.** You can simulate the distribution and installation of the code with your fresh changes. If you need help testing your changes locally, you can check out the doc on doing [local third-party testing](https://github.com/facebook/docusaurus/blob/main/admin/local-third-party-project-testing.md).

-[Check tags of all recently merged Pull-Requests](https://github.com/facebook/docusaurus/pulls?q=is%3Apr+sort%3Aupdated-desc+is%3Amerged+)
+Not all labels will appear in the changelog—some are designed not to. However, you should **always** label each PR, so that before release, we can do a quick scan and confirm no PR is accidentally left out. Here's a search query (pity that GH doesn't have wildcard queries yet):
 
-The `tag:` label prefix is for PRs only. Other labels are not used by the changelog tool, and it's not necessary to assign such labels to issues, only PRs.
+```
+is:pr is:merged sort:updated-desc -label:"pr: breaking change","pr: new feature","pr: bug fix","pr: performance","pr: polish","pr: documentation","pr: maintenance","pr: internal","pr: dependencies","pr: showcase"
+```

+
+Some general principles about the labeling process:
+
+- "Will an average user be interested in this entry?" Items like "improve test coverage", "upgrade dependencies" can probably be left out (we have `pr: internal` and `pr: dependencies` for this). However, "pin GitHub actions to an SHA", "add visual testing infrastructure", etc., albeit internal, could be interesting to the user, and can be included in the "maintenance" section.
+- "Will this change have tangible impact on the user?" A common case is when a PR implements a feature X, then there are immediately follow-up PRs that fix bugs or polish feature X. These follow-up PRs don't necessarily have to be in the changelog, and even if they alter the API, they are not breaking changes, because to an average user bumping their version, they will only see the new feature X as a whole. Make the entries atomic.
+
+The `pr:` label prefix is for PRs only. Other labels are not used by the changelog tool, and it's not necessary to assign such labels to issues, only PRs.

+# Argos visual regression tests
+
+We use [Argos CI](https://argos-ci.com) to detect visual regressions on Docusaurus.
+
+This workspace can be run manually, but is generally run through the [Argos GitHub Action](../.github/workflows/argos.yml).
+
+The workflow execute those following steps:
+
+- Build the website locally with `yarn build:website:fast`
+- Start the website server with `yarn serve:website` on [http://localhost:3000](http://localhost:3000)
+- Take screenshots of all pages found in `sitemap.xml` with Playwright
+- Upload all screenshots to [Argos CI](https://argos-ci.com)
+
+This workflow runs for `main` and PR branches, and add a commit status to each PR with a visual diff that we can easily inspect.
+
+---
+
+Some additional capabilities:
+
+- Use [./tests/screenshot.spec.ts](./tests/screenshot.spec.ts) to customize the screenshots we take, eventually filter out some useless sitemap pages like versioned docs
+- Use [./tests/screenshot.css](./tests/screenshot.css) to hide flaky CSS elements: iframe, video, gif...
