+# Contributions Guidelines
+
+## Restrictions on Generative AI Usage (AI Policy)
+
+> [!NOTE]
+> The following is adapted from [matplotlib's contributing guide](https://matplotlib.org/devdocs/devel/contribute.html#generative-ai) and the [Linux Kernel policy guide](https://www.kernel.org/doc./html/next/process/coding-assistants.html)
+
+We expect authentic engagement in our community.
+
+- Do not post output from Large Language Models or similar generative AI as comments on GitHub or our discord server, as such comments tend to be formulaic and low-quality content.
+- If you use generative AI tools as an aid in developing code or documentation changes, ensure that you fully understand the proposed changes and can explain why they are the correct approach.
+
+Make sure you have added value based on your personal competency to your contributions.
+Just taking some input, feeding it to an AI and posting the result is not of value to the project.
+To preserve precious core developer capacity, we reserve the right to rigorously reject seemingly AI generated low-value contributions.
+
+### Signed-off-by and Developer Certificate of Origin
+
+AI agents MUST NOT add Signed-off-by tags. Only humans can legally certify the Developer Certificate of Origin (DCO). The human submitter is responsible for:
+
+- Reviewing all AI-generated code
+- Ensuring compliance with licensing requirements
+- Adding their own Signed-off-by tag to certify the DCO
+- Taking full responsibility for the contribution
+
+See [Signing your work](#signing-your-work) for more information.
+
+### Attribution
+
+When AI tools contribute to development, proper attribution helps track the evolving role of AI in the development process. Contributions should include an Assisted-by tag in the commit message with the following format:
+
+```text
+Assisted-by: AGENT_NAME:MODEL_VERSION [TOOL1] [TOOL2]
+```
+
+Where:
+
+- `AGENT_NAME` is the name of the AI tool or framework
+- `MODEL_VERSION` is the specific model version used
+- `[TOOL1] [TOOL2]` are optional specialized analysis tools used (e.g., coccinelle, sparse, smatch, clang-tidy)
+
+Basic development tools (git, gcc, make, editors) should not be listed.
+
+Example:
+
+```text
+Assisted-by: Claude:claude-3-opus coccinelle sparse
+```
+
+## Bootstrapping MeshMC
+
+Please run ./bootstrap.sh or on your windows run .\bootstrap.cmd
+
+This scripts installs lefthook, reuse, go, zlib, extra-cmake-modules and more. But you need to install Qt6 with modules, this script install qt but only needs for quazip.
+
+In your in a Windows, you can install Qt with Online Installer.
+
+## Building MeshMC
+
+Please read [BUILD.md](BUILD.md) for building MeshMC
+
+## Signing your work
+
+In an effort to ensure that the code you contribute is actually compatible with the licenses in this codebase, we require you to sign-off all your contributions.
+
+This can be done by appending `-s` to your `git commit` call, or by manually appending the following text to your commit message:
+
+```text
+<commit message>
+
+Signed-off-by: Author name <Author email>
+```
+
+By signing off your work, you agree to the terms below:
+
+```text
+Developer's Certificate of Origin 1.1
+
+By making a contribution to this project, I certify that:
+
+(a) The contribution was created in whole or in part by me and I
+    have the right to submit it under the open source license
+    indicated in the file; or
+
+(b) The contribution is based upon previous work that, to the best
+    of my knowledge, is covered under an appropriate open source
+    license and I have the right under that license to submit that
+    work with modifications, whether created in whole or in part
+    by me, under the same open source license (unless I am
+    permitted to submit under a different license), as indicated
+    in the file; or
+
+(c) The contribution was provided directly to me by some other
+    person who certified (a), (b) or (c) and I have not modified
+    it.
+
+(d) I understand and agree that this project and the contribution
+    are public and that a record of the contribution (including all
+    personal information I submit with it, including my sign-off) is
+    maintained indefinitely and may be redistributed consistent with
+    this project or the open source license(s) involved.
+```
+
+These terms will be enforced once you create a pull request, and you will be informed automatically if any of your commits aren't signed-off by you.
+
+As a bonus, you can also [cryptographically sign your commits][gh-signing-commits] and enable [vigilant mode][gh-vigilant-mode] on GitHub.
+
+[gh-signing-commits]: https://docs.github.com/en/authentication/managing-commit-signature-verification/signing-commits

+
+## Contributor License Agreement (CLA)
+
+By submitting a contribution to this repository, you agree that your
+contribution is made under the terms of the **Project Tick Contributor
+License Agreement (CLA)**.
+
+The CLA ensures that:
+
+- you have the legal right to submit the contribution,
+- the contribution does not knowingly infringe third-party rights,
+- Project Tick may distribute the contribution under the applicable
+  Project Tick license(s) governing the component,
+- long-term governance and license consistency across the Project Tick
+  ecosystem can be maintained.
+
+The CLA applies to all intentional contributions, including but not
+limited to source code, documentation, tests, data, media assets, and
+configuration files.
+
+The full text of the current CLA is available at:
+
+- <https://projecttick.org/licenses/PT-CLA-2.0.txt>
+
+If you do not agree to the CLA, please do not submit contributions.
+
+## Backporting to Release Branches
+
+We use [automated backports](https://github.com/Project-Tick/MeshMC/blob/master/.github/workflows/backport.yml) to merge specific contributions from develop into `release` branches.
+
+This is done when pull requests are merged and have labels such as `backport release-7.x` - which should be added along with the milestone for the release.
