+# Contributing to Flutter Manga Reader
+
+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 `main` if you're working on a fix or `dev` if you're on a feature.
+2. If you've added code that should be tested, add tests.
+3. If you've changed APIs, update the documentation and write the migration steps.
+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/Floating-Dartists/matomo-tracker/issues)
+
+We use GitHub issues to track public bugs. Report a bug by [opening a new issue](https://github.com/Floating-Dartists/matomo-tracker/issues/new/choose); it's that easy!
+
+## Write bug reports with detail, background, and sample code
+
+**Great Bug Reports** tend to have:
+
+- A quick summary and/or background
+- Steps to reproduce
+  - Be specific!
+  - Give sample code if you can.
+- 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
+
+* [Flutter style guide](https://github.com/flutter/flutter/wiki/Style-guide-for-Flutter-repo)
+* [Dart style guide](https://dart.dev/effective-dart)
+* Avoid the usage of the `!` or `as` operators as they are not typesafe
