 Aether In a Box - 4G
 ====================
 
-The documentation for Aether In a Box (AiaB) - 4G is located in `Installing the 4G AIAB <https://docs.aetherproject.org/master/developer/aiab.html#installing-the-4g-aiab>`_,
-where specifics about setting up AiaB 4G, running 4G test, troubleshooting,

-______________
-
-Suppose you wish to test a new build of a 4G SD-CORE services. You can deploy
-custom images by editing ~/aether-in-a-box/sd-core-4g-values.yaml, for
-example::
-
-    images:
-      tags:
-        spgwc: omecproject/spgw:master-e419062
-
-To upgrade a running 4G SD-CORE with the new image, or to redeploy the 4G
-SD-CORE with the image::
-
-    make reset-test # delete 4G deployment if it was already started before updating image
-    make 4g-test  # now this deployment will use new spgwc image
+Currently `Aether OnRamp <https://docs.aetherproject.org/master/onramp/overview.html>`_
+doesn't support 4G deployment.
