 ## Expose Metrics: Measure anything
 
-Keymetrics allows you to expose any metrics from you code to the Keymetrics Dashboard, in realtime. These metrics takes place in the main Keymetrics Dashboard page under the Custom Metrics section.
+PMX allows you to expose any metrics from you code to the PM2 monit command or the Keymetrics Dashboard, in realtime and over time.
 
-4 helpers are available:
+4 measurement are available:
 
 - **Simple metrics**: Values that can be read instantly
     - eg. Monitor variable value
 - **Counter**: Things that increment or decrement
     - eg. Downloads being processed, user connected
 - **Meter**: Things that are measured as events / interval
     - eg. Request per minute for a http server
-- **Histogram**: Keeps a resevoir of statistically relevant values biased towards the last 5 minutes to explore their distribution
+- **Histogram**: Keeps a reservoir of statistically relevant values biased towards the last 5 minutes to explore their distribution
     - eg. Monitor the mean of execution of a query into database
