+# Java code for RabbitMQ tutorials
+
+Here you can find the Java code examples from [RabbitMQ
+tutorials](https://www.rabbitmq.com/getstarted.html).
+
+To successfully use the examples you will need a RabbitMQ node running locally.
+
+## Requirements
+
+### Linux
+
+- Note the source files are symbolic links to the [java](https://github.com/rabbitmq/rabbitmq-tutorials/tree/main/java) directory.
+
+### Windows
+
+- Run pull-source-files.bat to replace symbolic link to the actual source file.
+
+```shell
+.\pull-source-files.bat
+```
+
