+# Parallel Build with Smart Builder
+
+Add this line if you want to use the Smart Builder with 8 threads:
+
+`-T 8 -b smart`
+
+Enabling this by default causes issues with tests as it usually consumes more resources than a normal laptop has, and it also causes issues with the maven-release-plugin.
+
+If you are working in a mode where you are not running the tests than turning on this option may be more convenient.
+
+Note that you can still use this option from the command line and it will override the default single threaded builder listed the `.mvn/maven.config`.
