+
+The extension of official Redux+TS template with react-router for [Create React App](https://github.com/facebook/create-react-app).
+
+To use this template within your project, add `--template redux-typescript-router` when creating a new app.
+
+For example:
+
+```sh
+npx create-react-app my-app --template redux-typescript-router
+
+# or
+
+yarn create react-app my-app --template redux-typescript-router
+```
+
+Cloning this repo pulls down the Redux template only; not a bundled and configured Create React App.
