+
+Development setup
+-----------------
+
+The App is developed using Android Studio.
+
+For testing the app, you need to obtain API Keys for the 
+[GoingElectric API](https://www.goingelectric.de/stromtankstellen/api/)
+as well as for [Google APIs](https://console.developers.google.com/)
+("Maps SDK for Android" and "Places API" need to be activated). These APIs need to be put into the
+app in the form of a resource file called `apikeys.xml` under `app/src/main/res/values`, with the
+following content:
+
+```xml
+<resources>
+    <string name="google_maps_key" templateMergeStrategy="preserve" translatable="false">
+        insert your Google Maps key here
+    </string>
+    <string name="goingelectric_key" translatable="false">
+        insert your GoingElectric key here
+    </string>
+</resources>
+```
