-============================
+# Ceedling Plugin: Pretty Tests Report
 
-## Overview
+# Overview
 
-The stdout_pretty_tests_report is the default output of ceedling. Instead of
-showing most of the raw output of CMock, Ceedling, etc., it shows a simplified
-view. It also creates a nice summary at the end of execution which groups the 
-results into ignored and failed tests.
+This plugin is intended to be the default option for formatting a test suites
+results when displayed at the console. It collects raw test results from the 
+individual test executables of your test suite and presents them in a more 
+readable summary form.
 
-## Setup
+# Example Output
 
-Enable the plugin in your project.yml by adding `stdout_pretty_tests_report`
-to the list of enabled plugins.
