 ### How to Add Secrets
 
 1. Navigate to your GitHub repository
@@ -95,65 +97,8 @@ This workflow requires the following secrets to be configured in your GitHub rep
 Rename `infra/terraform.tfvars.examples` to `infra/terraform.tfvars` and add the following data:
   * project_prefix  = "Your project identifier name in **lower case** letters only - this will be applied as a prefix to all assets"
   * resource_owner = "Your-name"
-  * aws_region     = "AWS Region" ex. us-east-1
-  * azs            = ["us-east-1a", "us-east1b"] - Change to Correct Availability Zones based on selected Region
 
-### STEP 3: Modify variable.tf
-Modify the `S3/variable.tf` file inside the `S3 directory`:
-
-### Example Configuration:
-```hcl
-variable "tf_state_bucket" {
-  type        = string
-  description = "S3 bucket for Terraform state"
-  default     = "your-unique-bucket-name" 
-}
-```
-### STEP 4: Configure Backend.tf
-Add the S3 bucket name to the `Backend.tf` file in the `Infra/Backend.tf`, `eks-cluster/Backend.tf`, `Nap/Backend.tf`, `Policy/Backend.tf`, and `Arcadia/Backend.tf` directories. 
-
-### Example Configuration:
-
-```hcl
-terraform {
-  backend "s3" {
-    bucket         = "your-unique-bucket-name"       # Your S3 bucket name
-    key            = "infra/terraform.tfstate"       # Path to state file
-    region         = "us-east-1"                     # AWS region
-    dynamodb_table = "terraform-lock-table"          # DynamoDB table for state locking
-    encrypt        = true                        
-  }
-}
-```
-
-### STEP 5: Configuring `data.tf` for Remote State
-
-Each `data.tf` file in the following directories needs to use the correct format:
-
-- `eks-cluster/data.tf`
-- `Nap/data.tf`
-- `Policy/data.tf`
-- `Arcadia/data.tf`
-
-### Example Configuration:
-
-```hcl
-data "terraform_remote_state" "infra" {
-  backend = "s3"
-  config = {
-    bucket         = "your-unique-bucket-name"   # Your S3 bucket name
-    key            = "infra/terraform.tfstate"  # Path to your state file
-    region         = "us-east-1"                # AWS region
-  }
-}
-```
-### STEP 6: Set Bucket Name
-Add the name of your S3 bucket inside the and  [`destroy-nic-napv5.yml`](https://github.com/f5devcentral/nginx_automation_examples/blob/main/.github/workflows/destroy-nic-napv5.yml) workflow file, which is located in the Terraform _S3 job:
