+StatsD
+======
+
+Sometimes you need to count stuff.
+Maybe you need to know how long something took.
+
+
+Concepts
+--------
+
+* *buckets*
+  Each stat is in it's own "bucket". They are not predefined anywhere. Buckets can be named anything that will translate to Graphite (periods make folders, etc)
+
+* *values*
+  Each stat will have a value. How it is interpreted depends on modifiers
+  
+* *flush*
+  After the flush interval timeout (default 10 seconds), stats are munged and sent over to Graphite.
+
+Counting
+--------
+
+    gorets:1|c
+
+This is a simple counter. Add 1 to the "gorets" bucket. It stays in memory until the flush interval.
+
+
+Timing
+------
+
+    glork:320|ms
+
+The glork took 320ms to complete this time. StatsD figures out 90th percentile, average (mean), lower and upper bounds for the flush interval.
+
+Sampling
+--------
+
+    gorets:1|c|@0.1
+
+Tells StatsD that this counter is being sent sampled ever 1/10th of the time.
+
+
+Guts
+----
+
+* UDP
+  Client libraries use UDP to send information to the StatsD daemon.
+
+* NodeJS
+* Graphite
