 ## Indirectly Overriding Build Behavior (medium term use), and Advanced Options
 
 For build behavior that you'd like to persist across commits (e.g. defining the set of platforms to test against, disabling a test that you expect to re-enable at some future point), a special configuration file called `.arduino-ci.yml` can be used.  There are 3 places you can put them:
