 This project makes use of [`yarn`](https://yarnpkg.com/en/) to ensure that the exact same dependency versions are used every time you install it.
 
 * `yarn` creates a [`yarn.lock`](https://yarnpkg.com/en/docs/yarn-lock) to track those versions. That file is updated automatically by whenever dependencies are added/updated/removed via yarn.
-* **Adding new dependencies**: To install/add a new dependency (third party library), use [`yarn add`](https://yarnpkg.com/en/docs/cli/add). For example: `yarn add some-lib --save`.
-    * If it's a development-only dependency (not for production), use `yarn add some-lib --save-dev`
+* **Adding new dependencies**: To install/add a new dependency (third party library), use [`yarn add`](https://yarnpkg.com/en/docs/cli/add). For example: `yarn add some-lib`.
+    * If you are adding a new build tool dependency (to `devDependencies`), use `yarn add some-lib --dev`
 * **Upgrading existing dependencies**: To upgrade existing dependencies, you can use [`yarn upgrade`](https://yarnpkg.com/en/docs/cli/upgrade).  For example: `yarn upgrade some-lib` or `yarn upgrade some-lib@version`
 * **Removing dependencies**: If a dependency is no longer needed, or replaced, use [`yarn remove`](https://yarnpkg.com/en/docs/cli/remove) to remove it.
