+# Contributing to Lodash
+
+Contributions are always welcome. Before contributing please read the
+[code of conduct](https://github.com/lodash/lodash/blob/master/CODE_OF_CONDUCT.md)
+& [search the issue tracker](https://github.com/lodash/lodash/issues); your issue
+may have already been discussed or fixed in `master`. To contribute,
+[fork](https://help.github.com/articles/fork-a-repo/) Lodash, commit your changes,
+& [send a pull request](https://help.github.com/articles/using-pull-requests/).
+
+## Feature Requests
+
+Feature requests are always welcome. They should be submitted in the
+[issue tracker](https://github.com/lodash/lodash/issues), with a description of
+the expected behavior & use case, where they’ll remain closed until sufficient
+interest has been shown by the community. Before submitting a request,
+please search for similar ones in the
+[closed issues](https://github.com/lodash/lodash/issues?q=is%3Aissue+is%3Aclosed+label%3Aenhancement).
+
+## Pull Requests
+
+For additions or bug fixes you should only need to modify `lodash.js`. Include
+updated unit tests in the `test` directory as part of your pull request. Don’t
+worry about regenerating the `dist/` or `doc/` files.
+
+Before running the unit tests you’ll need to install, `npm i`,
+[development dependencies](https://docs.npmjs.com/files/package.json#devdependencies).
+Run unit tests from the command-line via `npm test`, or open `test/index.html` &
+`test/fp.html` in a web browser. The [Backbone](http://backbonejs.org/) &
+[Underscore](http://underscorejs.org/) test suites are included as well.

+## Coding Guidelines
+
+In addition to the following guidelines, please follow the conventions already
+established in the code.
+
+- **Spacing**:<br>
+  Use two spaces for indentation. No tabs.
+
+- **Naming**:<br>
+  Keep variable & method names concise & descriptive.<br>
+  Variable names `index`, `collection`, & `callback` are preferable to
+  `i`, `arr`, & `fn`.
+
+- **Quotes**:<br>
+  Single-quoted strings are preferred to double-quoted strings; however,
+  please use a double-quoted string if the value contains a single-quote
+  character to avoid unnecessary escaping.
+
+- **Comments**:<br>
+  Please use single-line comments to annotate significant additions, &
+  [JSDoc-style](http://www.2ality.com/2011/08/jsdoc-intro.html) comments for
+  functions.
+
+Guidelines are enforced using [JSCS](https://www.npmjs.com/package/jscs):
+
+```bash
+$ npm run style
+```
