Lifecycle of service and dependancies

From @rizplate on Tue Mar 20 2018 00:22:12 GMT+0000 (UTC)

Can someone point me to the documentation where the lifecycle of service and dependancies is shown?
i.e. when is a service created, is its init method called? when are dependencies started, injected and their init methods called
