+# Contributing to anybadge
+I love your input! I 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
+
+## I use [Github Flow](https://docs.github.com/en/get-started/quickstart/github-flow), so all code changes happen through pull requests
+Pull requests are the best way to propose changes to the codebase (I use 
+[Github Flow](https://docs.github.com/en/get-started/quickstart/github-flow)). I 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 (tbc)
+6. Issue that pull request!
+
+## Any contributions you make will be under the MIT Software License
+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/jongracecox/anybadge/issues)
+I use GitHub issues to track public bugs. Report a bug by
+[opening a new issue](https://github.com/jongracecox/anybadge/issues/new/choose).
+
+## 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 (ideally sample code that *anyone* with a basic setup can run to reproduce)
+- What you expected would happen - (include explanation, screenshot, drawings, etc. to be exact)
+- 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.
+
+## Use a Consistent Coding Style
+Please follow the existing coding style.

+# Technical stuff
+
+## Documentation
+The `README.md` file contains a table showing example badges for the different built-in colors. If you modify the
+appearance of badges, or the available colors please update the table using the following code:
+
+```python
+import anybadge
+print("""| Color Name | Hex Code | Example |
+| ---------- | -------- | ------- |""")
+for color in sorted([c for c in anybadge.colors.Color], key=lambda x: x.name):
+    file = 'examples/color_' + color.name.lower() + '.svg'
+    url = 'https://cdn.rawgit.com/jongracecox/anybadge/master/' + file
+    anybadge.Badge(label='Color', value=color, default_color=color.name.lower()).write_badge(file, overwrite=True)
+    print("| {color} | {hex} | ![]({url}) |".format(color=color.name.lower(), hex=color.value.upper(), url=url))
+```
