+
+
+🎉🚀🤘 Thanks for your interest in the Codeowners Validator project! 🤘🚀🎉
+
+This document contains contribution guidelines for this repository. Read it before you start contributing.
+
+## Contributing
+
+Before proposing or adding changes, check the [existing issues](https://github.com/mszostok/codeowners-validator/issues) and make sure the discussion/work has not already been started to avoid duplication.
+
+If you'd like to see a new feature implemented, use this [feature request template](https://github.com/mszostok/codeowners-validator/issues/new?assignees=&labels=&template=feature_request.md) to create an issue.
+
+Similarly, if you spot a bug, use this [bug report template](https://github.com/mszostok/codeowners-validator/issues/new?assignees=mszostok&labels=bug&template=bug_report.md) to let us know!
+

+To start contributing, follow these steps:
+
+1. Fork the `codeowners-validator` repository.

+
+## Prerequisites
+
+* [Go](https://golang.org/dl/) 1.15 or higher
+* [Docker](https://www.docker.com/)
+* Make
+
+Helper scripts may introduce additional dependencies. However, all helper scripts support the `INSTALL_DEPS` environment variable flag.
+By default, this flag is set to `false`. This way, the scripts will try to use the tools installed on your local machine. This helps speed up the development process.
+If you do not want to install any additional tools, or you want to ensure reproducible script
+results, export `INSTALL_DEPS=true`. This way, the proper tool version will be automatically installed and used.
+
+## Dependency management
+
+This project uses `go modules` for dependency management. To install all required dependencies, use the following command:
+
+```bash
+go mod download
+```
+
+## Testing
+
+### Unit tests
+
+To run all unit tests, execute:
+
+```bash
+make test-unit
+```
+
+To generate the unit test coverage HTML report, execute:
+
+```bash
+make test-unit-cover-html
+```
+
+> **NOTE:** The generated report opens automatically in your default browser.
+
+### Lint tests
+
+To check your code for errors, such as typos, wrong formatting, security issues, etc., execute:
+
+```bash
+make test-lint
+```
+
+To automatically fix detected lint issues, execute:
+
+```bash
+make fix-lint-issues
+```
+
+### Integration tests
+
+This project supports the integration tests that are defined in the [tests](../tests) package. The tests are executed against [`gh-codeowners/codeowners-samples`](https://github.com/gh-codeowners/codeowners-samples).
+
+> **CAUTION:** Currently, running the integration tests both on external PRs and locally by external contributors is not supported, as the teams used for testing are visible only to the organization members.
+> At the moment, the `codeowners-validator` repository owner is responsible for running these tests.
+
+## Build a binary
+
+To generate a binary for this project, execute:
+```bash
+make build
+```
+
+This command generates a binary named `codeowners-validator` in the root directory.
