+Built by a team of students for a school project, PassBuy enables the user to find the cheapest price for his shopping list in quick and easy steps.
+
+# Running the application
+
+To run it locally you need to have a key for the Google Places API.
+
+## Back-end
+
+In the *back-end* subfolder lies content for both the database and the NodeJS API. Instructions for running or using the API can be found there as well.
+
+## Front-end
+
+Similarly, the *front-end* subfolder contains the Android Studio project for our application as well as an Adobe XD project file for the application's design.
+
+## Utility Scripts
+
+The small-scale scripts that were used, in the early stages of our application, to gather and analyze data are located in the *Utility Scripts* subfolder.
