+## Linting
+
+Linters are a fundamental tool to any project - it ensures that code your working with has a consistent style, which is critical to writing readable code.
+
+Everyone has their own style, so Boilermaker does not come prepackaged with a linter. However, we `strongly` recommend that you (and your team, if working in a group) decide on a style, and stick with it. Here's what you need to do:
+
+* `npm install -g eslint`
+* In the root of your project, `eslint --init`
+* You will then be prompted to choose how you want to configure ESLint. We recommend selecting the `Use a popular style guide option`. The existing Boilermaker code was written in accordance with the `Standard` style, but you may choose a different one if you don't like it.
