+# React Notes App
+
+## Installation
+
+Pretty straightforward -- clone, initialize the submodules, install the node modules, start the servers.
+
+```
+git clone https://github.com/WordsofDefiance/react-notes.git
+git submodule init
+cd client && npm install && cd ../
+cd server && npm install && cd ../
+```
+
+Next, you will need to start the front-end and back-end servers.
+
+To start the back-end server:
+```
+cd server
+npx nodemon server.js
+```
+
+To start the front-end server:
+```
+cd client
+npm start
+```
