 # gitlab-docker-runner
+
+This Terraform module creates a GitLab Runner on AWS using one or more EC2 instances. The runner is registered with the provided GitLab instance and is capable of running Docker-based builds. Additionally, the module creates an AWS Key Pair that can be used to SSH into the EC2 instances.
+
+## Usage
+
+```hcl
+module "gitlab_docker_runner" {
+  source = "https://github.com/infraspecdev/terraform-aws-gitlab-docker-runner"
+    
+  ami_id                    = "ami-0675b5ed3c8c1f754"
+  instance_type             = "t2.micro"
+  instance_count            = 1
+  vpc_security_group_ids    = ["sg-0b0b0b0b0b0b0b0b0"]
+  subnet_id                 = "subnet-0b0e1c4b5b1b1b1b1"
+  gitlab_url                = "https://gitlab.example.com"
+  runner_registration_token = "runner-registration-token-here"
+  ssh_public_key            = "ssh-public-key-here"
+}
