+# AWS Security Group
+This creates a set of security groups that can be used on other items.
+
+## Retrieving the security group by name:
+
+The `sg_list` output data structure:
+```
+sg_list = {
+  "id" = [
+    "sg-0978d62cacw3e8b21",
+    "sg-06f385f8d8w319d59",
+    "sg-033cc7d494w3cbe47",
+    "sg-0071a0c41bwaea18e",
+  ]
+  "name" = [
+    "dev-foo",
+    "dev-app",
+    "dev-bar",
+    "dev-ami",
+  ]
+```
+
+Can use the `index` function to find an index by the name:
+```
+module.security_groups.sg_list["id"][index(module.security_groups.sg_list["name"], "dev-app")]
+```
