+`HierarchicalResourceQuota` of namespace `team-a`. All of the reasources of `team-a` are
+equally shared between the applications in their subnamespaces, which is very efficient.

+You have the struggle that each time some team calls you and asks you to modify their
+`ResourceQuota` or namespaces structure? HRQ fixes it!
+With the following teams tree:
+```
+company-a
+├── organization-a
+│   ├── org-a-team-1
+│   ├── org-a-team-2
+│   ...
+├── organization-b
+│   ├── org-b-team-1
+│   ├── org-b-team-2
+│   ...
+...
+```
+Instead of each team askin from the `cluster-admin` to modify their ResourceQuota, 
+you can make the following namespace hierarchy:
+```
+company-a-restrictions
+└── [s] company-a
+```
+And put the resources HRQ in the `company-a-restrictions` namespace. This will restrict
+whole `company-a` to the amount of resources that they are paying for. Then `company-a`
+can do similar HRQ with their organizations:
+```
+company-a-restrictions (has HRQ)
+└── [s] company-a
+    ├── [s] org-a-restrictions (has HRQ)
+    │   └── [s] organization-a
+    ├── [s] org-b-restrictions (has HRQ)
+    │   └── [s] organization-b
+    ...
+```
+This way each individual can fairly and securely distribute their resources across
+their members.
 
 when creating `HierarchicalResourceQuota`, HNC automatically creates `ResourceQuota`
 with name `local-impl-hrq` and propogates it to all subnamespaces. It monitors
