 rxcpp example of live twitter analysis
+
+This project was inspired by a [talk](https://blog.niallconnaughton.com/2016/10/25/ndc-sydney-talk/) by @nconnaughton - [github](https://github.com/NiallConnaughton/rx-realtime-twitter), [twitter](https://twitter.com/nconnaughton) 
+
+The goal for this app is to show rxcpp usage and explore machine learning on live data.
+
+This app demonstrates how multi-thread code can be written using rxcpp to hide all the primitives. thread, mutex, etc.. are all hidden.
+
+CMAKE is used for the build. There are depenedcies on several libraries. (curl, oauth, sdl2, opengl)
+
+This project has only been built and tested on OS X.
+
+There are several shortcuts in place - error handling and retry and completion handling have all gotten short-shrift.
