+    Ignite Spring configuration file to startup Ignite cache.
+
+    This file demonstrates how to configure cache using Spring. Provided cache
+    will be created on node startup.
+
+    Use this configuration file when running Redis examples (see 'examples/redis' folder).
+
+    When starting a standalone node, you need to execute the following command:
+    {IGNITE_HOME}/bin/ignite.{bat|sh} examples/config/redis/example-redis.xml
+
+    When starting Ignite from Java IDE, pass path to this file to Ignition:
+    Ignition.start("examples/config/redis/example-redis.xml");
