+## How to contribute
+
+### Reporting bugs
+
+This section guides you through submitting a bug report for Poetry.
+Following these guidelines helps maintainers and the community understand your report, reproduce the behavior, and find related reports.

When you are creating a bug report, please include as many details as possible. Fill out the [required template](https://github.com/sdispater/poetry/.github/ISSUE_TEMPLATE/1_Bug_report.md), the information it asks helps the maintainers resolve the issue faster.
+
+> **Note:** If you find a **Closed** issue that seems like it is the same thing that you're experiencing, open a new issue and include a link to the original issue in the body of your new one.
+
+#### Before submitting a bug report
+
+* **Check the [FAQs on the official website](https://poetry.eustace.io) for a list of common questions and problems.
+* **Check that your issue does not already exist in the [issue tracker](https://github.com/sdispater/poetry/issues).
+
+#### How do I submit a bug report
+
+Bugs are tracked on the [official issue tracker](https://github.com/sdispater/poetry/issues) where you can create a new one and provide the following information by filling in [the template](https://github.com/sdispater/poetry/.github/ISSUE_TEMPLATE/1_Bug_report.md).
+
+Explain the problem and include additional details to help maintainers reproduce the problem:
+
+* **Use a clear and descriptive title** for the issue to identify the problem.
+* **Describe the exact steps which reproduce the problem** in as many details as possible.
+* **Provide your pyproject.toml file** in a [Gist](https://gist.github.com) after removing potential private information (like private package repositories).
+* **Provide specific examples to demonstrate the steps to reproduce the issue**. Include links to files or GitHub projects, or copy/pasteable snippets, which you use in those examples.
+* **Describe the behavior you observed after following the steps** and point out what exactly is the problem with that behavior.
+* **Explain which behavior you expected to see instead and why.**
+* **If the problem is an unexpected error being raised**, execute the corresponding command in **debug** mode (the `-vvv` option).
+
+Provide more context by answering these questions:
+
+* **Did the problem start happening recently** (e.g. after updating to a new version of Poetry) or was this always a problem?
+* If the problem started happening recently, **can you reproduce the problem in an older version of Poetry?** What's the most recent version in which the problem doesn't happen?
+* **Can you reliably reproduce the issue?** If not, provide details about how often the problem happens and under which conditions it normally happens.
+
+Include details about your configuration and environment:
+
+* **Which version of Poetry are you using?** You can get the exact version by running `poetry -V` in your terminal.
+* **Which Python version Poetry has been installed for?** Execute the `debug:info` to get the information.
+* **What's the name and version of the OS you're using**?

+
+### Contributing to code
+
+#### Local development
+
+You will need Poetry to start contributing on the Poetry codebase. Refer to the [documentation](https://poetry.eustace.io/docs/#introduction) to start using Poetry.
+
+You will first need to clone the repository using `git` and place yourself in its directory:
+
+```bash
+$ git clone git@github.com:sdispater/poetry.git
+$ cd poetry
+```
+
+Now, you will need to install the required dependency for Poetry and be sure that the current
+tests are passing on your machine:
+
+```bash
+$ poetry develop
+$ poetry run pytest tests/
+```
+
+Poetry uses the [black](https://github.com/ambv/black) coding style and you must ensure that your
+code follows it. If not, the CI will fail and your Pull Request will not be merged.
+
+To make sure that you don't accidently commit code that does not follow the coding style, you can
+install a pre-commit hook that will check that everything is in order:
+
+```bash
+$ poetry run pre-commit install
+```
+
+Your code must always be accompanied by corresponding tests, if tests are not present your code
+will not be merged.
+
+#### Pull requests
+
+* Fill in [the required template](https://github.com/sdispater/poetry/.github/PULL_REQUEST_TEMPLATE.md)
+* Be sure that you pull request contains tests that cover the changed or added code.
+* If you changes warrant a documentation change, the pull request must also update the documentation.
