+# Contributing
+
+You **always** want to look at this file *before* contributing. In here you should find
+steps that you need to take to set up your development environment as well as instructions
+for coding standards and contributing guidelines.
+
+You'll notice that when this file is present, GitHub will give you an alert when creating
+a new issue, indicating that you should check out the guidelines first:
+
+![contributing-notice](other/contributing-notice.png)
+
+## Set up instructions
+
+1. Fork the repo
+2. Clone your fork
+3. Create a branch
+4. Run `npm install`
+5. Run `npm t && npm run build`. If everything works, then you're ready to make changes.
+6. Run `npm run test:watch`. See that it's watching your file system for changes.
+7. Make your changes and try to make the tests pass. If you can't or need help then commit what you have with `--no-verify` and make a PR
+8. If you get things working, add your changed files with `git add` and run `npm run commit` to get an interactive prompt for creating a commit message that follows [our standards](https://github.com/ajoslin/conventional-changelog/blob/master/conventions/angular.md)
+9. Push your changes to your fork with `git push`
+10. Create a pull request.
+11. Iterate on the solution.
+12. Get merged! 🎉 🎊
+
+## Commit messages
+
+We follow a convention for our commit messages, to learn about why and how, see [this free egghead.io series](http://kcd.im/write-oss)

+This is a collection of utility JavaScript functions copy/pasted and slightly modified from StackOverflow answers 😀
+
+This repo is used as the basis for an Egghead.io series I'm working on entitled: Contributing to an Open Source Project on GitHub
+
+## Usage
+
+```javascript
+import {flatten, snakeToCamel} from 'stack-overflow-copy-paste'
+
+flatten([[1, 2,], 3]) // [1, 2, 3]
+snakeToCamel('snake-case-string') // 'snakeCaseString'
+```
