+You are done if you will use only components and utilities provided by this
+package. If you are to use configurations, to build or test your code, you must
+also install the peer dependencies:
+```
+$ npm install -g install-peerdeps
+$ install-peerdeps -od topcoder-react-utils
+```
+
+Peer dependencies will be also stored as dev dependencies into `package.json` of
+your project, thus future invokations of `npm install` will automatically
+install them, and you won't need to use `install-peerdeps` as long as you don't
+update `topcoder-react-utils` version.
