+module: aci_context
+short_description: Manage private networks (aka. contexts) on Cisco ACI fabrics
+description:
+- Manage private networks (aka. contexts) on Cisco ACI fabrics.
+- Each context is a private network associated to a tenant, i.e. VRF.
+author:
+- Swetha Chunduri (@schunduri)
+- Dag Wieers (@dagwieers)
+- Jacob McGill (@jmcgill298)
+version_added: '2.4'
+requirements:
+- Tested with ACI Fabric 1.0(3f)+
+notes:
+- The tenant used must exist before using this module in your playbook. The M(aci_tenant) module can be used for this.
+options:
+  tenant:
+    description:
+    - The name of the Tenant the VRF should belong to.
+    aliases: [ tenant_name ]
+  vrf:
+    description:
+    - The name of the VRF.
+    aliases: [ context, name, vrf_name ]
+  policy_control_direction:
+    description:
+    - Determines if the policy should be enforced by the fabric on ingress or egress.
+    choices: [ egress, ingress ]
+  policy_control_preference:
+    description:
+    - Determines if the Fabric should enforce Contrac Policies.
+    choices: [ enforced, unenforced ]
+  description:
+    description:
+    - Description for the VRF.
+  state:
+    description:
+    - Use C(present) or C(absent) for adding or removing.
+    - Use C(query) for listing an object or multiple objects.
+    choices: [ absent, present, query ]
