+Apache Ignite ZeroMQ Streamer Module
+------------------------
+
+Apache Ignite ZeroMQ Streamer module provides streaming from ZeroMQ to Ignite cache.
+
+Starting data transfer to Ignite cache can be done with the following steps.
+
+1. Import Ignite ZeroMQ Streamer Module In Maven Project
+
+If you are using Maven to manage dependencies of your project, you can add ZeroMQ module
+dependency like this (replace '${ignite-zeromq-ext.version}' with actual Ignite version you are
+interested in):
+
+<project xmlns="http://maven.apache.org/POM/4.0.0"
+ xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
+ xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
+ http://maven.apache.org/xsd/maven-4.0.0.xsd">
+ ...
+ <dependencies>
+ ...
+ <dependency>
+ <groupId>org.apache.ignite</groupId>
+ <artifactId>ignite-zeromq-ext</artifactId>
+ <version>${ignite-zeromq-ext.version}</version>
+ </dependency>
+ ...
+ </dependencies>
+ ...
+</project>
+
+2. Create an Ignite configuration file (see example-ignite.xml) and make sure it is accessible from the streamer.
+
+3. Create your StreamSingleTupleExtractor or StreamMultipleTupleExtractor, an example can be found in the tests folder
+ZeroMqStringSingleTupleExtractor.java. Now it is necessary to add in a streamer
+IgniteZeroMqStreamer.setSingleTupleExtractor(...).
+
+4. Create a topology with the streamer and start.
