-  ### Simple Example
+  ### NEW_SECURITY_GROUP
   Here is an example of how you can use this module in your inventory structure:
   ```hcl
   # use this
     module "security_group" {
       source        = "clouddrove/security-group/aws"
       version       = "1.3.0"
-      name          = "security-group"
-      environment   = "test"
-      protocol      = "tcp"
-      label_order   = ["name", "environment"]
-      vpc_id        = "vpc-xxxxxxxxx"
-      allowed_ip    = ["172.16.0.0/16", "10.0.0.0/16"]
-      allowed_ipv6  = ["2405:201:5e00:3684:cd17:9397:5734:a167/128"]
-      allowed_ports = [22, 27017]
+      name        = "security-group"
+      environment = "test"
+      label_order = ["name", "environment"]
+    
+      vpc_id                = module.vpc.vpc_id
+      allowed_ip            = ["172.16.0.0/16", "10.0.0.0/16"]
+      allowed_ports         = [22, 27017]
+      security_groups       = ["sg-xxxxxxxxxxxx"]
+      prefix_list_ids       = ["pl-xxxxxxxxxxxx"]
     }
   ```
+  ### NEW_SECURITY_GROUP_WITH_EGRESS
+    module "security_group" {
+      source        = "clouddrove/security-group/aws"

+      environment = "test"
+      label_order = ["name", "environment"]
+    
+      vpc_id                = module.vpc.vpc_id
+      allowed_ip            = ["172.16.0.0/16", "10.0.0.0/16"]
+      allowed_ipv6          = ["2405:201:5e00:3684:cd17:9397:5734:a167/128"]
+      allowed_ports         = [22, 27017]
+      security_groups       = ["sg-xxxxxxxxx"]
+      prefix_list_ids       = ["pl-6da54004"]
+    
+      egress_rule            = true
+      egress_allowed_ip      = ["172.16.0.0/16", "10.0.0.0/16"]
+      egress_allowed_ports   = [22, 27017]
+      egress_protocol        = "tcp"
+      egress_prefix_list_ids = ["pl-xxxxxxxxx"]
+      egress_security_groups = ["sg-xxxxxxxxx"]
+    
+    }
+  ```
+  ### UPDATED_EXISTING
+  module "security_group" {
