+# Contributing to pdfstamp
+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.
+
+## We Use [Github Flow](https://guides.github.com/introduction/flow/index.html), So All Code Changes Happen Through Pull Requests
+Pull requests are the best way to propose changes to the codebase (we use [Github Flow](https://guides.github.com/introduction/flow/index.html)). We actively welcome your pull requests:
+
+1. Fork the repo and create your branch from `master`.
+2. If you've added code that should be tested, add tests.
+3. If you've changed APIs, update the documentation.
+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 MIT Software License
+In short, when you submit code changes, your submissions are understood to be under the same [MIT License](http://choosealicense.com/licenses/mit/) that covers the project. Feel free to contact the maintainers if that's a concern.
+
+## Report bugs using Github's [issues](https://github.com/mavaddat/pdfstamp/issues)
+We use GitHub issues to track public bugs. Report a bug by [opening a new issue](); it's that easy!
+
+## Write bug reports with detail, background, and sample code
+[This is an example](http://stackoverflow.com/q/12488905/180626) of a bug report I wrote, and I think it's not a bad model. Here's [another example from Craig Hockenberry](http://www.openradar.me/11905408), an app developer whom I greatly respect.
+
+**Great Bug Reports** tend to have:
+
+- A quick summary and/or background
+- Steps to reproduce
+  - Be specific!
+  - Give sample code if you can. [My StackOverflow question](http://stackoverflow.com/q/12488905/180626) includes sample code that *anyone* with a base R setup can run to reproduce what I was seeing
+- 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. I'm not even kidding.
+
+## Use a Consistent Coding Style
+I'm again borrowing these from [Facebook's Guidelines](https://github.com/facebook/draft-js/blob/main/CONTRIBUTING.md)
+
+* 2 spaces for indentation rather than tabs
+* You can try running `npm run lint` for style unification
+
+## License
+By contributing, you agree that your contributions will be licensed under its MIT License.
