+# Contribution to Testkube 
+
+Thanks for reaching out contribution 🎉
+
+If you're new in Open-source community there is nice guide how to start contributing to projects: 
+https://github.com/firstcontributions/first-contributions
+
+## Code of Conduct
+
+This project and everyone participating in it is governed by the Testkube [code of conduct](CODE_OF_CONDUCT.md)
+
+## Have questions or idea? 
+
+We're using github discussions for managing pre-development ideas and clarifications, feel free to add one at our [Q&A discussion page](https://github.com/kubeshop/testkube/discussions/categories/q-a)
+
+New ideas should be placed in [Ideas discussion page](https://github.com/kubeshop/testkube/discussions/categories/ideas)
+
+
+
+## General guidance for contributing to Testkube project
+
+You're very welcome to help in testkube development, there is a lot of incoming work to do :). 
+
+We're trying hard to limit technical debt from the beginning so we defined simple rules into Testkube repo to help with it.
+
+### For golang based components
+
+- Always use gofmt (there is only one true way of doing code formatting ;) ).
+- Follow golang good practices (proverbs) in your code.
+- Tests are your friend (we will target 80% CC in our code).
+- Use clean names, don't brake basic design patterns and rules.
+
+### For infrastructure / Kubernetes based components
+
+- We're using helm charts to build and share Testkube
+- Comment non-obvious decisions
+- Use current Helm/Kubernetes versions
+
+
+## How can I help?
+
+- By fixing [one of many Issues](https://github.com/kubeshop/testkube/issues) - simply fork our repo and create new Pull Request with new code changes. 
+- By helping to reach out valid results [from discussions](https://github.com/kubeshop/testkube/discussions)
