+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside

+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.

+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions

+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+
+Go package for creating, managing, inspecting, and destroying cgroups.
+The resources format for settings on the cgroup uses the OCI runtime-spec found
+[here](https://github.com/opencontainers/runtime-spec).
+
+## Examples (v1)
+
+### Create a new cgroup
+
+This creates a new cgroup using a static path for all subsystems under `/test`.
+
+* /sys/fs/cgroup/cpu/test
+* /sys/fs/cgroup/memory/test
+* etc....
+
+It uses a single hierarchy and specifies cpu shares as a resource constraint and
+uses the v1 implementation of cgroups.
+
+
+```go
+shares := uint64(100)
+control, err := cgroup1.New(cgroup1.StaticPath("/test"), &specs.LinuxResources{
+    CPU: &specs.LinuxCPU{
+        Shares: &shares,
+    },
+})
+defer control.Delete()
+```
+
+### Create with systemd slice support
+
+
+```go
+control, err := cgroup1.New(cgroup1.Systemd, cgroup1.Slice("system.slice", "runc-test"), &specs.LinuxResources{
+    CPU: &specs.CPU{
+        Shares: &shares,
+    },
+})
+
+```
+
+### Load an existing cgroup
+
+```go
+control, err = cgroup1.Load(cgroup1.Default, cgroups.StaticPath("/test"))
+```
+
+### Add a process to the cgroup
+
+```go
+if err := control.Add(cgroup1.Process{Pid:1234}); err != nil {
+}
+```
+
+###  Update the cgroup
+
+To update the resources applied in the cgroup
+
+```go
+shares = uint64(200)
+if err := control.Update(&specs.LinuxResources{
+    CPU: &specs.LinuxCPU{
+        Shares: &shares,
+    },
+}); err != nil {
+}
+```
+
+### Freeze and Thaw the cgroup
+
+```go
+if err := control.Freeze(); err != nil {
+}
+if err := control.Thaw(); err != nil {
+}
+```
+
+### List all processes in the cgroup or recursively
+
+```go
+processes, err := control.Processes(cgroup1.Devices, recursive)
+```
+
+### Get Stats on the cgroup
+
+```go
+stats, err := control.Stat()
+```
+
+By adding `cgroups.IgnoreNotExist` all non-existent files will be ignored, e.g. swap memory stats without swap enabled
+```go
+stats, err := control.Stat(cgroup1.IgnoreNotExist)
+```
+
+### Move process across cgroups
+
+This allows you to take processes from one cgroup and move them to another.
+
+```go
+err := control.MoveTo(destination)
+```
+
+### Create subcgroup
+
+```go
+subCgroup, err := control.New("child", resources)
+```
+
+### Registering for memory events
+
+This allows you to get notified by an eventfd for v1 memory cgroups events.
+
+```go
+event := cgroup1.MemoryThresholdEvent(50 * 1024 * 1024, false)
+efd, err := control.RegisterMemoryEvent(event)
+```
+
+```go
+event := cgroup1.MemoryPressureEvent(cgroup1.MediumPressure, cgroup1.DefaultMode)
+efd, err := control.RegisterMemoryEvent(event)
+```
+
+```go
+efd, err := control.OOMEventFD()
+// or by using RegisterMemoryEvent
+event := cgroup1.OOMEvent()
+efd, err := control.RegisterMemoryEvent(event)
+```
+
+## Examples (v2/unified)
+
+### Check that the current system is running cgroups v2
+
+```go
+var cgroupV2 bool
+if cgroups.Mode() == cgroups.Unified {
+	cgroupV2 = true
+}
+```
+
+### Create a new cgroup
+
+This creates a new systemd v2 cgroup slice. Systemd slices consider ["-" a special character](https://www.freedesktop.org/software/systemd/man/systemd.slice.html),
+so the resulting slice would be located here on disk:
+
+* /sys/fs/cgroup/my.slice/my-cgroup.slice/my-cgroup-abc.slice
+
+```go
+import (
+    "github.com/containerd/cgroups/v3/cgroup2"
+    specs "github.com/opencontainers/runtime-spec/specs-go"
+)
+
+res := cgroup2.Resources{}
+// dummy PID of -1 is used for creating a "general slice" to be used as a parent cgroup.
+// see https://github.com/containerd/cgroups/blob/1df78138f1e1e6ee593db155c6b369466f577651/v2/manager.go#L732-L735
+m, err := cgroup2.NewSystemd("/", "my-cgroup-abc.slice", -1, &res)
+if err != nil {
+	return err
+}
+```
+
+### Load an existing cgroup
+
+```go
+m, err := cgroup2.LoadSystemd("/", "my-cgroup-abc.slice")
+if err != nil {
+	return err
+}
+```
+
+### Delete a cgroup
+
+```go
+m, err := cgroup2.LoadSystemd("/", "my-cgroup-abc.slice")
+if err != nil {
+	return err
+}
+err = m.DeleteSystemd()
+if err != nil {
+	return err
+}
+```
+
+### Kill all processes in a cgroup
+
+```go
+m, err := cgroup2.LoadSystemd("/", "my-cgroup-abc.slice")
+if err != nil {
+	return err
+}
+err = m.Kill()
+if err != nil {
+	return err
+}
+```
+
+### Attention
+
+All static path should not include `/sys/fs/cgroup/` prefix, it should start with your own cgroups name

+//     vmstat/zoneinfo/memcg or internal memory usage statistics and free any
+//     resources that can be easily reconstructed or re-read from a disk.
+//   - The "critical" level means that the system is actively thrashing, it is
+//     about to out of memory (OOM) or even the in-kernel OOM killer is on its
+//     way to trigger. Applications should do whatever they can to help the
