 Installation
 -----------
 jMeter:
--- go to http://jmeter.apache.org/download_jmeter.cgi and download jMeter in Source section (pay you attention that Java 6 or later is required)
+-- go to http://jmeter.apache.org/download_jmeter.cgi and download jMeter in Binary section (pay you attention that Java 6 or later is required)
 -- unzip archive
 
 Plugins (only if you want to use additional reports (like graphs)):
 -- go to http://jmeter-plugins.org/downloads/all/ and download JMeterPlugins-Standard and JMeterPlugins-Extras
 -- unzip them to appropriate ext directory of your jMeter instance.
+-- additional reports can now be enabled via GUI (right click them, then click Enable) or editing the jMeter JMX XML (set 'enabled="true"').
 
 
 Usage
 -----------
+Before running the jMeter tests for the first time, you will need to first use generate.php to generate the test data.
+
+If you do not wish to use performance metrics gathered from the server(s) (such as CPU / IO load), or do not wish to configure the jMeter metric gathering software on your server(s), you can disable that either via the GUI (right click on "Performance Metrics Collector" and click Disable) or by editing the jMeter JMX XML from:
+<kg.apc.jmeter.perfmon.PerfMonCollector guiclass="kg.apc.jmeter.vizualizers.PerfMonGui" testclass="kg.apc.jmeter.perfmon.PerfMonCollector" testname="Performance Metrics Collector" enabled="true">
+to:
+<kg.apc.jmeter.perfmon.PerfMonCollector guiclass="kg.apc.jmeter.vizualizers.PerfMonGui" testclass="kg.apc.jmeter.perfmon.PerfMonCollector" testname="Performance Metrics Collector" enabled="false">
+Attempting to run with Performance Metrics Collector enabled without appropriately configuring it will result in a timeout error connecting to the collector and the test not running.
