+# Contributing to tmux-notify
+
+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://docs.github.com/en/get-started/quickstart/github-flow)). 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/rickstaa/tmux-notify/issues)
+
+We use GitHub issues to track public bugs. Report a bug by [opening a new issue](https://github.com/rickstaa/tmux-notify/issues/new/choose); 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
+
+We use [shfmt](https://github.com/mvdan/sh#shfmt) to format our shell scripts. The easiest way to use [shfmt](https://github.com/mvdan/sh#shfmt) is through the [bash-beautify](https://marketplace.visualstudio.com/items?itemName=shakram02.bash-beautify) or [shell-format](https://marketplace.visualstudio.com/items?itemName=foxundermoon.shell-format) VS Code extensions.
