+Apache Ignite Hibernate Module
+------------------------------
+
+Apache Ignite Hibernate module provides Hibernate second-level cache (L2 cache) implementation based
+on Apache Ignite In-Memory Data Grid.
+
+To enable Hibernate module when starting a standalone node, move 'optional/ignite-hibernate' 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 Hibernate Module In Maven Project
+-------------------------------------------
+
+If you are using Maven to manage dependencies of your project, you can add Hibernate module
+dependency like this (replace '${ignite.version}' with actual Ignite version you are
+interested in):
+
+<project xmlns="http://maven.apache.org/POM/4.0.0"
+ xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
+ xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
+ http://maven.apache.org/xsd/maven-4.0.0.xsd">
+ ...
+ <dependencies>
+ ...
+ <dependency>
+ <groupId>org.apache.ignite</groupId>
+ <artifactId>ignite-hibernate_4.2</artifactId>
+ <version>${ignite.version}</version>
+ </dependency>
+ ...
+ </dependencies>
+ ...
+</project>
+
+
+LGPL dependencies
+-----------------
+
+Ignite includes the following optional LGPL dependencies:
+ - Hibernate L2 Cache Integration, http://hibernate.org/orm/
+ - JTS Topology Suite for Geospatial indexing, http://tsusiatsoftware.net/jts/main.html
+ - cron4j for cron-based task scheduling, http://www.sauronsoftware.it/projects/cron4j
+
+Apache binary releases cannot include LGPL dependencies. If you would like include
+optional LGPL dependencies into your release, you should download the source release
+from Ignite website and do the build with the following maven command:
+
+./mvnw clean package -DskipTests -Prelease,lgpl
