+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

+## Code of Conduct
+
+This project and everyone participating in it is governed by the
+[Shulkerscript CLI Code of Conduct](https://github.com/moritz-hoelting/shulkerscript-cli/blob/main/CODE_OF_CONDUCT.md).
+By participating, you are expected to uphold this code. Please report unacceptable behavior
+to .
+
+
+## I Have a Question
+
+> If you want to ask a question, we assume that you have read the available [Documentation](https://shulkerscript.hoelting.dev/).
+> When asking about a missing feature, please make sure that it is not already on the [Roadmap](https://shulkerscript.hoelting.dev/roadmap).
+
+Before you ask a question, it is best to search for existing [Issues](https://github.com/moritz-hoelting/shulkerscript-cli/issues) that might help you. In case you have found a suitable issue and still need clarification, you can write your question in this issue. It is also advisable to search the internet for answers first.
+
+If you then still feel the need to ask a question and need clarification, we recommend either [writing an email](mailto:shulkerscript@hoelting.dev) or opening an issue on GitHub:
+
+- Open an [Issue](https://github.com/moritz-hoelting/shulkerscript-cli/issues/new).
+- Provide as much context as you can about what you're running into.
+- Add the `Question` label to the issue.
+- Provide project and platform versions (Windows/Linux/macOS), depending on what seems relevant.
+
+We will then take care of the issue as soon as possible.
+
+## I Want To Contribute
+
+> ### Legal Notice <!-- omit in toc -->
+> When contributing to this project, you must agree that you have authored 100% of the content, that you have the necessary rights to the content and that the content you contribute may be provided under the project license.
+
+### Reporting Bugs
+
+<!-- omit in toc -->
+#### Before Submitting a Bug Report
+
+A good bug report shouldn't leave others needing to chase you up for more information. Therefore, we ask you to investigate carefully, collect information and describe the issue in detail in your report. Please complete the following steps in advance to help us fix any potential bug as fast as possible.
+
+- Make sure that you are using the latest version.
+- Determine if your bug is really a bug and not an error on your side e.g. using incompatible environment components/versions (Make sure that you have read the [documentation](https://shulkerscript.hoelting.dev/). If you are looking for support, you might want to check [this section](#i-have-a-question)).
+- To see if other users have experienced (and potentially already solved) the same issue you are having, check if there is not already a bug report existing for your bug or error in the [bug tracker](https://github.com/moritz-hoelting/shulkerscript-cli/issues?q=label%3Abug).
+- Collect information about the bug:
+- Stack trace (Traceback)
+- OS, Platform and Version (Windows, Linux, macOS, x86, ARM)
+- Version of the CLI.
+- Possibly your input and the output
+- Can you reliably reproduce the issue? And can you also reproduce it with older versions?
+
+<!-- omit in toc -->
+#### How Do I Submit a Good Bug Report?
+
+> You must never report security related issues, vulnerabilities or bugs including sensitive information to the issue tracker, or elsewhere in public. Instead sensitive bugs must be sent by email to .
+<!-- You may add a PGP key to allow the messages to be sent encrypted as well. -->
+
+We use GitHub issues to track bugs and errors. If you run into an issue with the project:
+
+- Open an [Issue](https://github.com/moritz-hoelting/shulkerscript-cli/issues/new). (Since we can't be sure at this point whether it is a bug or not, we ask you not to talk about a bug yet and not to label the issue.)
+- Explain the behavior you would expect and the actual behavior.
+- Please provide as much context as possible and describe the *reproduction steps* that someone else can follow to recreate the issue on their own. This usually includes your code. For good bug reports you should isolate the problem and create a reduced test case.
+- Provide the information you collected in the previous section.
+
+Once it's filed:
+
+- The project team will label the issue accordingly.
+- A team member will try to reproduce the issue with your provided steps. If there are no reproduction steps or no obvious way to reproduce the issue, the team will ask you for those steps and mark the issue as `needs-repro`. Bugs with the `needs-repro` tag will not be addressed until they are reproduced.
+- If the team is able to reproduce the issue, it will be marked `needs-fix`, as well as possibly other tags (such as `critical`), and the issue will be left to be [implemented by someone](#your-first-code-contribution).
+
+<!-- You might want to create an issue template for bugs and errors that can be used as a guide and that defines the structure of the information to be included. If you do so, reference it here in the description. -->
+
+
+### Suggesting Enhancements
+
+This section guides you through submitting an enhancement suggestion for Shulkerscript CLI, **including completely new features and minor improvements to existing functionality**. Following these guidelines will help maintainers and the community to understand your suggestion and find related suggestions.
+
+<!-- omit in toc -->
+#### Before Submitting an Enhancement
+
+- Make sure that you are using the latest version.
+- Read the [documentation](https://shulkerscript.hoelting.dev/) carefully and find out if the functionality is already covered, maybe by an individual configuration.
+- Perform a [search](https://github.com/moritz-hoelting/shulkerscript-cli/issues) to see if the enhancement has already been suggested. If it has, add a comment to the existing issue instead of opening a new one.
+- 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. Keep in mind that we want features that will be useful to the majority of our users and not just a small subset. If you're just targeting a minority of users, consider writing an add-on/plugin library.
+
+<!-- omit in toc -->
+#### How Do I Submit a Good Enhancement Suggestion?
+
+Enhancement suggestions are tracked as [GitHub issues](https://github.com/moritz-hoelting/shulkerscript-cli/issues).
+
+- Use a **clear and descriptive title** for the issue to identify the suggestion.
+- Provide a **step-by-step description of the suggested enhancement** in as many details as possible.
+- **Describe the current behavior** and **explain which behavior you expected to see instead** and why. At this point you can also tell which alternatives do not work for you.
+- **Explain why this enhancement would be useful** to most Shulkerscript CLI users. You may also want to point out the other projects that solved it better and which could serve as inspiration.
+
+<!-- You might want to create an issue template for enhancement suggestions that can be used as a guide and that defines the structure of the information to be included. If you do so, reference it here in the description. -->
+
+### Your First Code Contribution
+Think about which part of the project your idea fits into. Do you want to work on [the cli](https://github.com/moritz-hoelting/shulkerscript-cli), [the language](https://github.com/moritz-hoelting/shulkerscript-lang) or [the datapack generation](https://github.com/moritz-hoelting/shulkerbox)?
+
+- Make sure you have [Rust](https://www.rust-lang.org/tools/install) installed.
+- Fork the repository and clone it to your local machine.
+- Create a new branch for your feature or bug fix.
+- Make your changes and commit them to your branch.
+- Push your changes to your fork.
+- Open a pull request in the original repository and describe the changes you made.
+
+### Improving The Documentation
+If you want to improve the documentation, you can do so by editing the [documentation repository](https://github.com/moritz-hoelting/shulkerscript-webpage).
+
+- Make sure you have [Node.js](https://nodejs.org/en/download) and [PNPM](https://pnpm.io/installation) installed.
+- Fork the repository and clone it to your local machine.
+- Create a new branch for your changes.
+- Start the development server with `pnpm dev --open`.
+- Make your changes and commit them to your branch.
+- Push your changes to your fork.
+- Open a pull request in the original repository and describe the changes you made.

+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes

+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions

+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"

+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,

+
+   3. Grant of Patent License. Subject to the terms and conditions of

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+

+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade

+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+

+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf

+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
