+# Adyen Android Assignment
+
+This repository contains the coding challenge for candidates applying for a Senior Android role at Adyen.
+It consists of two unrelated parts:
+
+## 1. Cash Register
+Your first task is to implement a cash register. See the `cashregister` module.
+
+Criteria:
+- The `CashRegister` gets initialized with some `Change`.
+- When performing a transaction, it either returns a `Change` object or fails with a `TransactionException`.
+- The `CashRegister` keeps track of the `Change` that's in it.
+
+Bonus points:
+- The cash register returns the minimal amount of change (i.e. the minimal amount of coins / bills).
+
+## 2. App
+Your second task is to implement a small app using the Foursquare Places API. See the `app` module.
+
+The app should show a list of venues around the user’s current location.
+Decide yourself which venue details should be relevant to the user. You have full freedom on how to present data on screen.
+We've already added some code to make it a bit easier for you, but you are free to change any part of it.
+We are going to check your implementation for understanding Android specifics (like handling configuration changes), UX choices, and overall architecture.
+You are free to add any feature or code you want, but we also value quality over quantity, so whatever you decide to do, try to show us your best.
+
+### Setup
+Add your Foursquare client ID and secret to `local.gradle`. See `local.gradle.example` for details.
+Tip: You can verify your credentials with `src/test/java/com/adyen/android/assignment/PlacesUnitTest.kt`# FoursquareApiCompose
+# FoursquareApiCompose
