-### Profile Activation
-
-To include code samples when building and testing the project, enable the 
-`enable-samples` Maven profile.
-
-#### Command line
-
-To activate the Maven profile on the command line add `-Penable-samples` to your
-Maven command.
-
-#### Maven `settings.xml`
-
-To activate the Maven profile in your `~/.m2/settings.xml` add an entry of
-`enable-samples` following the instructions in [Active Profiles][2].
-
-This method has the benefit of applying to all projects you build (and is
-respected by IntelliJ IDEA) and is recommended if you are going to be
-contributing samples to several projects.
-
-#### IntelliJ IDEA
-
-To activate the Maven Profile inside IntelliJ IDEA, follow the instructions in
-[Activate Maven profiles][3] to activate `enable-samples`.
