+# Maps API for JavaScript
+
+This repository holds a series of JavaScript based examples using the **HERE Maps API for JavaScript**. More information about the API can be found on [developer.here.com](https://developer.here.com/).
+
+This set of self-contained, use-case based examples is designed to be cloned by developers for their own use.
+
+
+**Note:** In order to get the sample code to work, you **must** replace all instances of `{YOUR_APP_ID}` and `{YOUR_APP_CODE}` within the code and use your own HERE credentials.
+
+You can obtain a set of credentials from the [Plans Page](https://developer.here.com/plans/api/consumer-mapping) on developer.here.com.
+
