+# Getting Started with Create React App
+
+This project was bootstrapped with [Create React App](https://github.com/facebook/create-react-app).
+
+A modified version of the dashboard, with anonymized participant responses. (No open-text answers)
+
+## How to run:
+
+(Run all commands in the root directory)
+- Install all packages. (via "npm install")
+- Run "npm start". This will open up the API, running on port 5000 alongside the dashboard running on port 3000.
+- Open "localhost:3000" and enjoy. :)
