+==== Importing into Intellij
+Spring Cloud projects use annotation processing, particularly Lombok, which requires configuration
+or you will encounter compile problems. It also needs a specific version of maven and a profile
+enabled. Intellij 14.1+ requires some configuration to ensure these are setup properly.
+
+ 1. Click Preferences, Plugins. *Ensure Lombok is installed*
+ 2. Click New, Project from Existing Sources, choose your spring-cloud-sleuth directory
+ 3. Choose Maven, and select Environment Settings. *Ensure you are using Maven 3.3.3*
+ 4. In the next screen, *Select the profile `spring`* click Next until Finish.
+ 5. Click Preferences, "Build, Execution, Deployment", Compiler, Annotation Processors. *Click Enable Annotation Processing*
+ 6. Click Build, Rebuild Project, and you are ready to go!
