+# Contributor Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to make participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, gender identity and expression, level of experience,
+nationality, personal appearance, race, religion, or sexual identity and
+orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+  advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+  address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at `service@swis.nl`. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at [http://contributor-covenant.org/version/1/4][version]

+# PHPStan Faker Provider Extension
+
+[![Latest Version on Packagist][ico-version]][link-packagist]
+[![Software License][ico-license]](LICENSE.md)
+[![Buy us a tree][ico-treeware]][link-treeware]
+[![Total Downloads][ico-downloads]][link-downloads]
+[![Maintained by SWIS][ico-swis]][link-swis]
+
+This PHPStan Reflection Extension can automatically register the methods and properties created by custom Faker providers, so you don't need to instruct PHPStan to ignore the usage of those methods.
+
+## Installation
+
+Via Composer
+
+```bash
+composer require --dev swisnl/phpstan-faker
+```
+
+If you also have [phpstan/extension-installer](https://github.com/phpstan/extension-installer) installed, then you don't need to follow the instructions for manual installation. Regardless of the installation method, you need to follow the instructions for configuration.
+
+<details>
+  <summary>Manual installation</summary>
+
+If you don't want to use `phpstan/extension-installer`, include extension.neon in your project's PHPStan config:
+
+```neon
+includes:
+    - vendor/swisnl/phpstan-faker/extension.neon
+```
+</details>
+
+## Configuration
+
+Add the custom faker provider classes to the extension configuration.
+
+```neon
+parameters:
+    faker:
+        providerClasses:
+            - App\Faker\MyProvider
+```
+
+**This does not actually register the custom providers in Faker, this just tells PHPStan about the custom providers.**
+
+## Changelog
+
+Please see [CHANGELOG](CHANGELOG.md) for more information on what has changed recently.
+
+## Contributing
+
+Please see [CONTRIBUTING](CONTRIBUTING.md) and [CODE_OF_CONDUCT](CODE_OF_CONDUCT.md) for details.
+
+## Security
+
+If you discover any security related issues, please email security@swis.nl instead of using the issue tracker.

+## Credits
