+### The SCSS linter
+
+To keep our styling scalable and consistent, we are using an [scss linter](https://www.npmjs.com/package/ember-cli-scss-lint) that will throw an error in the build if you do not conform to it's syntax rules. The syntax rules are defined in the [`.scss-lint.yml`](https://github.com/HospitalRun/hospitalrun-frontend/blob/master/.scss-lint.yml) file, and documentation for each linter is [available here](https://github.com/brigade/scss-lint/blob/master/lib/scss_lint/linter/README.md).
+
+The easiest way to work with styles in the project and abide by our linting rules is to install the [linter-scss-lint](https://atom.io/packages/linter-scss-lint) package for Atom. The package will then show you in real time where your styles are breaking the linter and how to correct them.
