+
+This is a moderately thin PHP API for [Amplitude](https://amplitude.com/), powerful enough to do what you need without getting in the way.  Designed to work well in 2 main scenarios:
+
+* **Same user & Amplitude App** - When you are tracking possibly multiple events, all for the same user, all for the same Amplitude app.  This library provides a singleton method that allows persisting the user and API key.
+* **Multiple Users / Same or Different Amplitude Apps** - For times you may need to log multiple events for a lot of different users, possibly using different amplitude apps.
+
+# Work in Progress
+
+We're still working documenting all the things and working out any kinks, but should have version 1.0.0 ready soon, stay tooned!
