@@ -13,6 +13,7 @@ There are a few arguments you can pass to the utility.
 `pkgJson` : pass your apps `package.json`: eg: `require("./package.json");`
 `ignoreVersion`: you can ignore versions on some shared packages. This utility supports versioned dependencies, which is a problem when using React as there can only be one version on the page
 `ignorePatchVersion` : ignore patch numbers and share dependencies based on a minor version matching. lodash-4.11 instead of lodash-4.11.7
+`shareFrom`: choose where in package.json the utility should share from. `['dependencies','peerDependencies']`/ (default: `dependencies`)
