+Apache Ignite Spring Module
+---------------------------
+
+Apache Ignite Spring Data module provides an integration with Spring Data framework.
+
+To enable Spring Data module when starting a standalone node, move 'optional/ignite-spring-data' folder to
+'libs' folder before running 'ignite.{sh|bat}' script. The content of the module folder will
+be added to classpath in this case.
+
+Importing Spring Data Module In Maven Project
+----------------------------------------
+
+If you are using Maven to manage dependencies of your project, you can add Spring module
+dependency like this (replace '${ignite.version}' with actual Ignite version you are
+interested in):
+
+<project xmlns="http://maven.apache.org/POM/4.0.0"
