+Tips:
+
+* If containerd gets stuck on something and enables debug socket, `ctr pprof goroutines`
+  dumps the golang stack of containerd, which is helpful! If containerd runs
+  without debug socket, `kill -SIGUSR1 $(pidof containerd)` also dumps the stack
+  as well.
+
+* If there is something about running containerd, like consuming more CPU resources,
+  `ctr pprof` subcommands will help you to get some useful profiles. Enable debug
+  socket makes life easier.
