+## CGroups
+
+powered by
+
+### systemd System and Service manager
+
+...
+
+### Hierarchy
+
+_Networks_, _nodes_ and _commands_ \
+are forming a Unified Cgroup Hierarchy (v2):
+
+```shell
+$ systemd-cgls
+...
+├─gont.slice
+│ └─gont-barlow.slice
+│   └─gont-barlow-h1.slice
+│     └─gont-run-2797869.scope
+│       └─2797869 sleep 3600
+```
+
+...
+
+### Freeze, Thaw, Kill
+
+All processes of a Cgroup can be controlled together:
+
+```go
+cmd.Freeze()   // Suspends all processes, included forked sub-processes
+
+cmd.Thaw()     // Resumes all processes
+
+cmd.Teardown() // Sends a SIGKILL to all processes
+```
+
+This also works on the _host_ and _network_ levels.
+
+...
+
+### Clean shutdown
+
+By default, `Close()` will invoke `Teardown()`.
+
+Hence, guaranteeing that no lingering processes will stick around.
+
+...
+
+### Resource Control
+
+We can control resource quota's in each level of the hierarchy using systemd resource control properties:
+
+```go
+import sdopt "github.com/cunicu/gont/v2/options/systemd"
+
+network, _ := gont.NewNetwork("mynet",
+  sdopt.AllowedCPUs(0b1100))
+
+host1, _ := network.AddHost("host1",
+  sdopt.TasksMax(10))
+
+cmd := host1.Command("long-running-command",
+  sdopt.RuntimeMax(10 * time.Second))
+
+cmd := host1.Command("memory-hungry-command",
+  sdopt.MemoryMax(1 << 20))
+```
