 # Structure outline of `common`-module
 
+## Lifetime
+
+The process begins in a platform specific module by creating a new Dagger `Component` that resolves all dependencies for `PlanSystem`.
+
+- When the plugin is enabled by the platform it is running on `PlanSystem#enable` is called, which will lead to all subsystems getting started in a specific order.
+- When the platform is shutting down and the plugin is disabled `PlanSystem#disable` is called, which stops all extra threads and closes resources the plugin is using.
+- When the plugin is reloaded with `plan reload` command by user, first the plugin is disabled and then enabled. A new Dagger component is created in the process, so `PlanSystem` instance is new each time the process enables.
