+Prometheus is a generic time series collection and computation server that is
+useful in the following fields:
+
+1. Industrial Experimentation / Real-Time Behavioral Validation / Software Release Qualification
+2. Econometric and Natural Sciences
+3. Operational Concerns and Monitoring
+
+The system is designed to collect telemetry from named targets on given
+intervals, evaluate rule expressions, display the results, and trigger an
+action if some condition is observed to be true.

-## Initial Hurdles
-
-  1. A bit of this grew organically without an easy way of binding it all together.  The tests will pass but slowly.  They were not optimized for speed but end-to-end coverage of the whole storage model.  This is something immediate to fix.
-  2. Protocol Buffer generator for Go changed emitted output API.  This will need to be fixed before other contributors can participate.

-## Milestones
-
-  1. In-memory archive, basic rule language, simple computation engine, and naive exposition system.
