+ingress-restrictions
+=========
+
+This role is used to help reduce the chances for backflip correlation from public ssh keys from tools like Censys.
+
+This will automatically tell middle hosts to only allow connections on port 2222 from edge hosts.
+
+This role only handles the sketch infrastructure as of now.
+
+Requirements
+------------
+
+Once you've ran this in your Sketch infrastructure, you will need to grab the IP Addresses or IP Address range from your middles and add them to your OCI/AWS infrastructure manually.
+
+Whenever we do the grand restructure, this should be done automatically for you everywhere.
+
+Example Playbook
+----------------
+
+```yml
+- hosts: all
+  roles:
+    - ingress-restrictions
+```
