+Periodically collects and pushes VM metrics to arbitrary consumer processes,
+which, in-turn, can do whatever they want with the given data (such as
+serialize and forward to some time series storage). Includes, off by default,
+example implementations of consumers for:
+
+- StatsD (`beam_stats_consumer_statsd`)
+- Graphite (`beam_stats_consumer_graphite`)
+- CSV file (`beam_stats_consumer_csv`)
 
-Essentially like `folsomite`, but better. Better in the following ways:
+Essentially like `folsomite`, but different. Different in the following ways:
 
 - More-general: consumers other than graphite can be defined
 - More-focused: only concerned with VM metrics, while `folsomite` ships off
   _everything_ from `folsom` (in addition to VM metrics)
-- Easier-to-reason-about implementation: well-defined metrics-to-binary
-  conversions, as opposed to the nearly-arbitrary term-to-string conversions
-  used in `folsomite`
-- Spec'd, tested and Dialyzed

+### Adding consumers
+
+#### At app config time
+
+```erlang
+{env,
+  [ {production_interval , 30000}
+  , {consumers,
+      [ {beam_stats_consumer_statsd,
+          [ {consumption_interval , 60000}
+          , {dst_host             , "localhost"}
+          , {dst_port             , 8125}
+          , {src_port             , 8124}
+          , {num_msgs_per_packet  , 10}
+          ]}
+      , {beam_stats_consumer_graphite,
+          [ {consumption_interval , 60000}
+          , {host                 , "localhost"}
+          , {port                 , 2003}
+          , {timeout              , 5000}
+          ]}
+      , {beam_stats_consumer_csv,
+          [ {consumption_interval , 60000}
+          , {path                 , "beam_stats.csv"}
+          ]}
+      , {some_custom_consumer_module,
+          [ {some_custom_option_a, "abc"}
+          , {some_custom_option_b, 123}
+          ]}
+
+      ]}
+  ]}
+```
+
+#### Dynamically
+
+```erlang
+beam_stats_consumer:add(consumer_module, ConsumerOptions).
+```
+
+### Removing consumers
+
+Not yet implemented.
