+This example shows integration with scalafmt plugin.
+
+Reformat executed on every `cbt compile` call, and affects only *.scala source files.
+
+You can provide your custom scalfmt preferences in build via `scalafmtConfig`.
+
+To see formatting in action: execute `cbt breakFormatting` to break formatting and then execute`cbt scalafmt` to get formatting back.
+
+To check if your code is properly formatted(for example as part of CI validation), you can execute:
+
+```
+cbt scalafmt
+git diff --exit-code
+```
+
+Last command will return non-zero code, if your code isn't properly formatted.
