+# Nutritional Facts
+Use this script to retrieve the nutritional information of your favorite food items!
+
+## Setup instructions
+### Packages
+- Install all required packages using this `pip install -r requirements.txt`.
+
+### API Key
+- Before you run the script you will need to receive a CalorieNinja API Key.
+- To do this got to the [CalorieNinja](https://calorieninjas.com/register) website and create an account, which is completely free.
+- Once you have made an account you can receive a free API-Key by navigating through the tabs and generating one.
+- Once you have received an API Key you may paste it into the code here `headers={"X-API-key": "YOUR-API-KEY"}`.
+
+## Output
+Here is an example use case of me using the script to find out the nutrition of chicken.
