+        When reporting bugs, please follow the guidelines in this template. This helps identify the problem precisely and thus enables contributors to fix it faster.
+        - Write a descriptive issue title above.
+        - The golden rule is to **always open *one* issue for *one* bug**. If you notice several bugs and want to report them, make sure to create one new issue for each of them.
+        - Search [open](https://github.com/godotengine/godot/issues) and [closed](https://github.com/godotengine/godot/issues?q=is%3Aissue+is%3Aclosed) issues to ensure it has not already been reported. If you don't find a relevant match or if you're unsure, don't hesitate to **open a new issue**. The bugsquad will handle it from there if it's a duplicate.
+        - Verify that you are using a [supported Godot version](https://docs.godotengine.org/en/latest/about/release_policy.html). Please always check if your issue is reproducible in the latest version – it may already have been fixed!
+        - If you use a custom build, please test if your issue is reproducible in official builds too. Likewise if you use any C++ modules, GDExtensions, or editor plugins, you should check if the bug is reproducible in a project without these.
+
+  - type: textarea
+    attributes:
+      label: Tested versions
+      description: |
+        To properly fix a bug, we need to identify if the bug was recently introduced in the engine, or if it was always present.
+        - Please specify the Godot version you found the issue in, including the **Git commit hash** if using a development or non-official build. The exact Godot version (including the commit hash) can be copied by clicking the version shown in the editor (bottom bar) or in the project manager (top bar).
+        - If you can, **please test earlier Godot versions** (previous stable branch, and development snapshots of the current feature release) and, if applicable, newer versions (development snapshots for the next feature release). Mention whether the bug is reproducible or not in the versions you tested. You can find all Godot releases in our [download archive](https://godotengine.org/download/archive/).
+        - The aim is for us to identify whether a bug is a **regression**, i.e. an issue that didn't exist in a previous version, but was introduced later on, breaking existing functionality. For example, if a bug is reproducible in 4.2.stable but not in 4.1.stable, we would like you to test intermediate 4.2 dev and beta snapshots to find which snapshot is the first one where the issue can be reproduced.
+      placeholder: |
+
+        - Reproducible in: 4.3.dev [d76c1d0e5], 4.2.stable, 4.2.dev5 and later 4.2 snapshots.
+        - Not reproducible in: 4.1.3.stable, 4.2.dev4 and earlier 4.2 snapshots.

+        - Specify the OS version, and when relevant hardware information.
+        - For issues that are likely OS-specific and/or graphics-related, please specify the CPU model and architecture.
+        - For graphics-related issues, specify the GPU model, driver version, and the rendering backend (GLES2, GLES3, Vulkan).
+        - **Bug reports not including the required information may be closed at the maintainers' discretion.** If in doubt, always include all the requested information; it's better to include too much information than not enough information.
+        - **Starting from Godot 4.1, you can copy this information to your clipboard by using *Help > Copy System Info* at the top of the editor window.**
+      placeholder: Windows 10 - Godot v4.0.3.stable - Vulkan (Forward+) - dedicated NVIDIA GeForce GTX 970 (nvidia, 510.85.02) - Intel Core i7-10700KF CPU @ 3.80GHz (16 Threads)

+        Describe your issue briefly. What doesn't work, and how do you expect it to work instead?
+        You can include images or videos with drag and drop, and format code blocks or logs with <code>\`\`\`</code> tags, on separate lines before and after the text. (Use <code>\`\`\`gdscript</code> to add GDScript syntax highlighting.)
+        Please do not add code examples or error messages as screenshots, but as text, this helps searching for issues and testing the code. If you are reporting a bug in the editor interface, like the script editor, please provide both a screenshot *and* the text of the code to help with testing.

+      description: |
+        - A small Godot project which reproduces the issue, with no unnecessary files included. Be sure to not include the `.godot` folder in the archive (but keep `project.godot`).
+        - Having an MRP is very important for contributors to be able to reproduce the bug in the same way that you are experiencing it. When testing a potential fix for the issue, contributors will use the MRP to validate that the fix is working as intended.
+        - If the reproduction steps are not project dependent (e.g. the bug is visible in a brand new project), you can write "N/A" in the field.
+        - Drag and drop a ZIP archive to upload it (max 10 MB). **Do not select another field until the project is done uploading.**
+        - **Note for C# users:** If your issue is *not* C#-specific, please upload a minimal reproduction project written in GDScript. This will make it easier for contributors to reproduce the issue locally as not everyone has a .NET setup available.

+# specific needs covered here, you can add them to:

+# Godot Engine authors
+
+Godot Engine is developed by a community of voluntary contributors who
+contribute code, bug reports, documentation, translations, support, etc.,
+across multiple repositories.
+
+It is impossible to list them all; nevertheless, this file aims at listing
+the developers who contributed significant improvements to the engine code.
+
+To keep the list curated, we use a threshold of a minimum of 11 commits.
+
+This file does not strictly reflect copyright ownership for the engine
+source code. For this, refer to the Git history to know which contributor
+wrote which part of the codebase.
+
+GitHub usernames are indicated in parentheses, or as sole entry when no other
+name is available.

+# Contributors guidelines
+
+This document summarizes the most important points for people interested in
+contributing to Godot, especially via bug reports or pull requests.
+
+Godot has a dedicated [Contributing documentation](https://contributing.godotengine.org/en/latest/organization/how_to_contribute.html)
+which details these points and more, and is a recommended read.
+
+## Table of contents
+
+- [Reporting bugs](#reporting-bugs)
+- [Proposing features or improvements](#proposing-features-or-improvements)
+- [Contributing pull requests](#contributing-pull-requests)
+- [Contributing to Godot translations](#contributing-to-godot-translations)
+- [Communicating with developers](#communicating-with-developers)
+
+## Reporting bugs
+
+Report bugs [here](https://github.com/godotengine/godot/issues/new?assignees=&labels=&template=bug_report.yml).
+Please follow the instructions in the template when you do.
+
+Notably, please include a Minimal Reproduction Project (MRP), which is a small
+Godot project which reproduces the issue, with no unnecessary files included.
+Be sure to not include the `.godot` folder in the archive to save space.
+
+Make sure that the bug you are experiencing is reproducible in the latest Godot
+releases. You can find an overview of all Godot releases [on the website](https://godotengine.org/download/archive/)
+to confirm whether your current version is the latest one. It's worth testing
+against both the latest stable release and the latest dev snapshot for the next
+Godot release.
+
+If you run into a bug which wasn't present in an earlier Godot version (what we
+call a _regression_), please mention it and clarify which versions you tested
+(both the one(s) working and the one(s) exhibiting the bug).
+
+## Proposing features or improvements
+
+**The main issue tracker is for bug reports and does not accept feature proposals.**
+
+Instead, head to the [Godot Proposals repository](https://github.com/godotengine/godot-proposals)
+and follow the instructions in the README file and issue template.
+
+## Contributing pull requests
+
+If you want to add new engine features, please make sure that:
+
+- This functionality is desired, which means that it solves a common use case
+  that several users will need in their real-life projects.
+- You talked to other developers on how to implement it best. See also
+  [Proposing features or improvements](#proposing-features-or-improvements).
+- Even if it doesn't get merged, your PR is useful for future work by another
+  developer.
+
+Similar rules can be applied when contributing bug fixes - it's always best to
+discuss the implementation in the bug report first if you are not 100% about
+what would be the best fix.
+
+You can refer to the [Pull request review process](https://contributing.godotengine.org/en/latest/organization/pull_requests/review_guidelines.html)
+for insights into the intended lifecycle of pull requests. This should help you
+ensure that your pull request fulfills the requirements.
+
+In addition to the following tips, also take a look at the
+[Engine development guide](https://docs.godotengine.org/en/latest/engine_details/development/index.html)
+for an introduction to developing on Godot.
+
+The [Contributing docs](https://contributing.godotengine.org/en/latest/organization/how_to_contribute.html)
+also have important information on the [PR workflow](https://contributing.godotengine.org/en/latest/organization/pull_requests/creating_pull_requests.html)
+(with a helpful guide for Git usage), and our [Code style guidelines](https://contributing.godotengine.org/en/latest/engine/guidelines/code_style.html)
+which all contributions need to follow.
+
+### Be mindful of your commits
+
+Try to make simple PRs that handle one specific topic. Just like for reporting
+issues, it's better to open 3 different PRs that each address a different issue
+than one big PR with three commits. This makes it easier to review, approve, and
+merge the changes independently.
+
+When updating your fork with upstream changes, please use ``git pull --rebase``
+to avoid creating "merge commits". Those commits unnecessarily pollute the git
+history when coming from PRs.
+
+Also try to make commits that bring the engine from one stable state to another
+stable state, i.e. if your first commit has a bug that you fixed in the second
+commit, try to merge them together before making your pull request. This
+includes fixing build issues or typos, adding documentation, etc.
+
+See our [PR workflow](https://contributing.godotengine.org/en/latest/organization/pull_requests/creating_pull_requests.html)
+documentation for tips on using Git, amending commits and rebasing branches.
+
+This [Git style guide](https://github.com/agis-/git-style-guide) also has some
+good practices to have in mind.
+
+### Format your commit messages with readability in mind
+
+The way you format your commit messages is quite important to ensure that the
+commit history and changelog will be easy to read and understand. A Git commit
+message is formatted as a short title (first line) and an extended description
+(everything after the first line and an empty separation line).
+
+The short title is the most important part, as it is what will appear in the
+changelog or in the GitHub interface unless you click the "expand" button.
+Try to keep that first line under 72 characters, but you can go slightly above
+if necessary to keep the sentence clear.
+
+It should be written in English, starting with a capital letter, and usually
+with a verb in imperative form. A typical bugfix would start with "Fix", while
+the addition of a new feature would start with "Add". A prefix can be added to
+specify the engine area affected by the commit. Some examples:
+
+- Add C# iOS support
+- Show doc tooltips when hovering properties in the theme editor
+- Fix GLES3 instanced rendering color and custom data defaults
+- Core: Fix `Object::has_method()` for script static methods
+
+If your commit fixes a reported issue, please include it in the _description_
+of the PR (not in the title, or the commit message) using one of the
+[GitHub closing keywords](https://docs.github.com/en/issues/tracking-your-work-with-issues/linking-a-pull-request-to-an-issue)
+such as "Fixes #1234". This will cause the issue to be closed automatically if
+the PR is merged. Adding it to the commit message is easier, but adds a lot of
+unnecessary updates in the issue distracting from the thread.
+
+Here's an example of a well-formatted commit message (note how the extended
+description is also manually wrapped at 80 chars for readability):
+
+```text
+Prevent French fries carbonization by fixing heat regulation
+
+When using the French fries frying module, Godot would not regulate the heat
+and thus bring the oil bath to supercritical liquid conditions, thus causing
+unwanted side effects in the physics engine.
+
+By fixing the regulation system via an added binding to the internal feature,
+this commit now ensures that Godot will not go past the ebullition temperature
+of cooking oil under normal atmospheric conditions.
+```
+
+**Note:** When using the GitHub online editor or its drag-and-drop
+feature, *please* edit the commit title to something meaningful. Commits named
+"Update my_file.cpp" won't be accepted.
+
+### Document your changes
+
+If your pull request adds methods, properties or signals that are exposed to
+scripting APIs, you **must** update the class reference to document those.
+This is to ensure the documentation coverage doesn't decrease as contributions
+are merged.
+
+[Update documentation XML files](https://contributing.godotengine.org/en/latest/documentation/class_reference.html)
+using your compiled binary, then fill in the descriptions.
+Follow the style guide described in the
+[Documentation writing guidelines](https://contributing.godotengine.org/en/latest/documentation/guidelines/docs_writing_guidelines.html).
+
+If your pull request modifies parts of the code in a non-obvious way, make sure
+to add comments in the code as well. This helps other people understand the
+change without having to dive into the Git history.
+
+### Write unit tests
+
+When fixing a bug or contributing a new feature, we recommend including unit
+tests in the same commit as the rest of the pull request. Unit tests are pieces
+of code that compare the output to a predetermined *expected result* to detect
+regressions. Tests are compiled and run on GitHub Actions for every commit and
+pull request.
+
+Pull requests that include tests are more likely to be merged, since we can have
+greater confidence in them not being the target of regressions in the future.
+
+For bugs, the unit tests should cover the functionality that was previously
+broken. If done well, this ensures regressions won't appear in the future
+again. For new features, the unit tests should cover the newly added
+functionality, testing both the "success" and "expected failure" cases if
+applicable.
+
+Feel free to contribute standalone pull requests to add new tests or improve
+existing tests as well.
+
+See [Unit testing](https://contributing.godotengine.org/en/latest/engine/unit_tests.html)
+for information on writing tests in Godot's C++ codebase.
+
+## Contributing to Godot translations
+
+You can contribute to Godot translations on [Hosted Weblate](https://hosted.weblate.org/projects/godot-engine/),
+an open source and web-based translation platform.
+
+Please refer to our [editor and documentation localization guidelines](https://contributing.godotengine.org/en/latest/documentation/translation/index.html)
+for an overview of the translation resources and what they correspond to.
+
+## Communicating with developers
+
+The Godot Engine community has [many communication
+channels](https://godotengine.org/community), some used more for user-level
+discussions and support, others more for development discussions.
+
+To communicate with developers (e.g. to discuss a feature you want to implement
+or a bug you want to fix), the following channels can be used:
+
+- [Godot Contributors Chat](https://chat.godotengine.org): You will
+  find most core developers there, so it's the go-to platform for direct chat
+  about Godot Engine development. Browse the [Directory](https://chat.godotengine.org/directory/channels)
+  for an overview of public channels focusing on various engine areas which you
+  might be interested in.
+- [Bug tracker](https://github.com/godotengine/godot/issues): If there is an
+  existing issue about a topic you want to discuss, you can participate directly.
+  If not, you can open a new issue. Please mind the guidelines outlined above
+  for bug reporting.
+- [Feature proposals](https://github.com/godotengine/godot-proposals/issues):
+  To propose a new feature, we have a dedicated issue tracker for that. Don't
+  hesitate to start by talking about your idea on the Godot Contributors Chat
+  to make sure that it makes sense in Godot's context.
+
+Thanks for your interest in contributing!
+

+## 2D and 3D cross-platform game engine
+
+**[Godot Engine](https://godotengine.org) is a feature-packed, cross-platform
+game engine to create 2D and 3D games from a unified interface.** It provides a
+comprehensive set of [common tools](https://godotengine.org/features), so that
+users can focus on making games without having to reinvent the wheel. Games can
+be exported with one click to a number of platforms, including the major desktop
+platforms (Linux, macOS, Windows), mobile platforms (Android, iOS), as well as
+Web-based platforms and [consoles](https://docs.godotengine.org/en/latest/tutorials/platform/consoles.html).
+
+## Free, open source and community-driven
+
+Godot is completely free and open source under the very permissive [MIT license](https://godotengine.org/license).
+No strings attached, no royalties, nothing. The users' games are theirs, down
+to the last line of engine code. Godot's development is fully independent and
+community-driven, empowering users to help shape their engine to match their
+expectations. It is supported by the [Godot Foundation](https://godot.foundation/)
+not-for-profit.
+
+Before being open sourced in [February 2014](https://github.com/godotengine/godot/commit/0b806ee0fc9097fa7bda7ac0109191c9c5e0a1ac),
+Godot had been developed by [Juan Linietsky](https://github.com/reduz) and
+[Ariel Manzur](https://github.com/punto-) (both still maintaining the project)
+for several years as an in-house engine, used to publish several work-for-hire
+titles.
+

+
+## Getting the engine
+
+### Binary downloads
+
+Official binaries for the Godot editor and the export templates can be found
+[on the Godot website](https://godotengine.org/download).
+
+### Compiling from source
+
+[See the official docs](https://docs.godotengine.org/en/latest/engine_details/development/compiling)
+for compilation instructions for every supported platform.
+
+## Community and contributing
+
+Godot is not only an engine but an ever-growing community of users and engine
+developers. The main community channels are listed [on the homepage](https://godotengine.org/community).
+
+The best way to get in touch with the core engine developers is to join the
+[Godot Contributors Chat](https://chat.godotengine.org).
+
+To get started contributing to the project, see the [contributing guide](CONTRIBUTING.md).
+This document also includes guidelines for reporting bugs.
+
+## Documentation and demos
+
+The official documentation is hosted on [Read the Docs](https://docs.godotengine.org).
+It is maintained by the Godot community in its own [GitHub repository](https://github.com/godotengine/godot-docs).
+
+The [class reference](https://docs.godotengine.org/en/latest/classes/)
+is also accessible from the Godot editor.
+
+We also maintain official demos in their own [GitHub repository](https://github.com/godotengine/godot-demo-projects)
+as well as a list of [awesome Godot community resources](https://github.com/godotengine/awesome-godot).
+
+There are also a number of other
+[learning resources](https://docs.godotengine.org/en/latest/community/tutorials.html)
+provided by the community, such as text and video tutorials, demos, etc.
+Consult the [community channels](https://godotengine.org/community)
+for more information.
