 ## Installation
 
-To install the plugin, build the project and copy the generated **jmeter-amqp-plugin-VERSION-jar-with-dependencies.jar** from `target/dist` to `$JMETER_HOME/lib/ext` directory, then restart JMeter GUI.
+1. Download the [latest release](https://github.com/aliesbelik/jmeter-amqp-plugin/releases/latest) or [build your own](#build) from the source code.
+2. Put `jmeter-amqp-plugin-VERSION-jar-with-dependencies.jar` into `$JMETER_HOME/lib/ext` directory.\
 It contains the necessary AMQP client dependency, no other jars are required.
+3. Restart JMeter GUI.
 
-In case if you need the plugin without the AMQP client included, you can use the **jmeter-amqp-plugin-VERSION.jar**, but you have to ensure that the [RabbitMQ client library](https://www.rabbitmq.com/java-client.html) - **amqp-client-VERSION.jar** - is installed in `$JMETER_HOME/lib` directory.
