+### host_volume Rules
+
+The `host_volume` policy controls access to mounting and accessing host volumes.
+
+```
+host_volume "*" {
+  policy = "write"
+}
+
+host_volume "prod-*" {
+  policy = "deny"
+}
+
+host_volume "prod-ca-certificates" {
+  policy = "read"
+}
+```
+
+Host volume rules are keyed to the volume names that they apply to. As with
+namespaces, you may use wildcards to reuse the same configuration across a set
+of volumes. In addition to the coarse grained policy specification, the
+host_volume stanza allows setting a more fine grained list of capabilities.
+This includes:
+
+- `deny` - Do not allow a user to mount a volume in any way.
+- `mount-readonly` - Only allow the user to mount the volume as `readonly`
+- `mount-readwrite` - Allow the user to mount the volume as `readonly` or `readwrite` if the host_volume configuration allows it.
+
+The course grained policy permissions are shorthand for the fine grained capabilities:
+
+- `deny` policy - ["deny"]
+- `read` policy - ["mount-readonly"]
+- `write` policy - ["mount-readonly", "mount-readwrite"]
+
+When both the policy short hand and a capabilities list are provided, the capabilities are merged.
+
+**Note:** Host Volume policies are applied when attempting to _use_ a volume,
+however, if a user has access to the Node API, they will be able to see that a
+volume exists in the `nomad node status` output regardless of this configuration.

 ### Resetting ACL Bootstrap
 
 If all management tokens are lost, it is possible to reset the ACL bootstrap so that it can be performed again.
