+# Quick Start
+
+Recursively clone this repository and `cd` into the root folder:
+
+```
+$ git clone --recursive git@git.unl.edu:soft-core/soft-260/dynamic-programming-practice.git
+$ cd dynamic-programming-practice
+```
+
+(If you forget `--recursive` when cloning, you can `cd` into your clone and run
+`git submodule update --init --recursive` instead.)
+
+Install dependencies:
+
+```
+$ npm install
+```
+
+And then serve the application locally:
+
+```
+$ npm start
+```
+
+When you are done, press control-c to stop the server.
