-#How to build
-Two Google API keys are needed to build this project:
- Google Map API key
- Google Backup API key
-
-Those keys can be obtained using the [Google API console](https://console.developers.google.com/apis/).
-
-As keys are not meant to be shared, they are located in their own value file: `/myTracks/src/main/res/values/apikeys.xml`, which is *git-ignored*. This means you have to **create it in your local project** to be able to build. Here is how it should look:
-
-```xml
-<?xml version="1.0" encoding="utf-8"?>
-<resources>
-  <string name="backup_api_key">xxxxxx</string>
-  <string name="maps_api_key">yyyyyy</string>
-</resources>
-```
-
-Once you have added this file, the project should be able to find and use your keys.
-
-Note: you can use any other file if you prefer than `apikeys.xml`, but in that case be careful to not commit it.
