+# Contributing to Elsa Workflows
+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 to 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 `develop`.
+1. Issue that pull request!
+
+## Any contributions you make will be under the New BSD License
+In short, when you submit code changes, your submissions are understood to be under the same [New BSD License](https://github.com/elsa-workflows/elsa-core/blob/master/LICENSE) that covers the project. Feel free to contact the maintainers if that's a concern.
+
+## Report bugs using Github's [issues](https://github.com/elsa-workflows/elsa-core/issues)
+We use GitHub issues to track public bugs. Report a bug by [opening a new issue](https://github.com/elsa-workflows/elsa-core/issues/new); 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
+As a default, I am applying [Microsoft's Coding Conventions for .NET](https://docs.microsoft.com/en-us/visualstudio/ide/editorconfig-code-style-settings-reference).
