+We love your input! We want to make contributing to this project as easy and transparent as possible, whether it's:
+
+- Reporting a bug
+- Discussing the current state of the code
+- Submitting a fix
+- Proposing new features
+- Becoming a maintainer
+
+## We Develop with Github
+We use github to host code, to track issues and feature requests, as well as accept pull requests.
+
+## Stay in touch
+
+Join us in [slack](https://luet.slack.com/join/shared_invite/enQtOTQxMjcyNDQ0MDUxLWQ5ODVlNTI1MTYzNDRkYzkyYmM1YWE5YjM0NTliNDEzNmQwMTkxNDRhNDIzM2Y5NDBlOTZjZTYxYWQyNDE4YzY#/) and hang out with the community! It will be much easier to get started and do your first steps in contributing to the project.
+
+## All Code Changes Happen Through Pull Requests
+Pull requests are the best way to propose changes to the codebase. We actively welcome your pull requests:
+
+1. Fork the repo you want to contribute to and create your branch from `develop`.
+2. If you've added code that should be tested, add tests.
+3. If you've changed APIs, update the [documentation](https://github.com/Luet-lab/docs).
+4. Ensure the test suite passes.
+5. Make sure your code lints.
+6. Issue that pull request!
+
+## Any contributions you make will be under the Software License of the repository
+In short, when you submit code changes, your submissions are understood to be under the same License that covers the project. Feel free to contact the maintainers if that's a concern.
+
+## Report bugs using Github's [issues](https://github.com/mudler/luet/issues)
+We use GitHub issues to track public bugs. Report a bug by [opening a new issue](https://github.com/mudler/luet/issues/new); it's that easy!
+
+## Write bug reports with detail, background, and sample code
+Try to be as more descriptive as possible. When opening a new issue you will be prompted to choose between a bug or a feature request, with a small template to fill details with. Be specific!
+
+**Great Bug Reports** tend to have:
+
+- A quick summary and/or background
+- Steps to reproduce
+  - Be specific!
+  - Give sample code if you can. 
+- What you expected would happen
+- What actually happens
+- Notes (possibly including why you think this might be happening, or stuff you tried that didn't work)
+
+People *love* thorough bug reports.

 Luet is a multi-platform Package Manager based off from containers - it uses Docker (and others) to build packages. It has zero dependencies and it is well suitable for "from scratch" environments. It can also version entire rootfs and enables delivery of OTA-alike updates, making it a perfect fit for the Edge computing era and IoT embedded devices.
 
 It offers a simple [specfile format](https://luet-lab.github.io/docs/docs/concepts/packages/specfile/) in YAML notation to define both [packages](https://luet-lab.github.io/docs/docs/concepts/packages/) and [rootfs](https://luet-lab.github.io/docs/docs/concepts/packages/#package-layers). As it is based on containers, it can be also used to build stages for Linux From Scratch installations and it can build and track updates for those systems.
 
 It is written entirely in Golang and where used as package manager, it can run in from scratch environment, with zero dependencies.

 ## In a glance
 
 - Luet can reuse Gentoo's portage tree hierarchy, and it is heavily inspired from it.
