 # Valheim Terraform
 
 ### Instructions:
-- Clone this repo
-- Create `terraform.auto.tfvars` like so:
+- Create a directory for your local terraform state, such as `valheim-terraform`
+- Create `main.tf` like so:
 ```
-key_name       = "my_ssh_key"
-world_name     = "HashiWorld"
-world_password = "hunter2"
+provider "aws" {
+  region = "us-east-1"
+}
+
+module "valheim-server" {
+  source         = "github.com/kpenfound/valheim-server?ref=v0.2.0"
+  key_name       = "my_aws_keypair_name"
+  world_name     = "Valheim-friends"
+  world_password = "hunter2"
+}
 ```
 - terraform apply
 - In Steam, go to View > Servers > Favorites > Add Server
-- Add your server at {ECS Instance IP}:2457
+- Add your server at {NLB DNS}:2457
 - Open valheim, select the server, and click connect!
 
 
 ### Important notes
 The default ecs_ami is the current ecs optimized ami in us-east-1.  You will
 have to change this for other regions. Refer to this list: https://docs.aws.amazon.com/AmazonECS/latest/developerguide/ecs-optimized_AMI.html
 
+This is using the docker image maintained by mbround18 at https://hub.docker.com/r/mbround18/valheim
 
-If you do not want your game to appear in the community list, set `world_public=0`
+### Auto Sleep
+Automatically shuts off the server after 0 players have been connected for a set amount of time.
 
+The next time a player tries to connect through steam, the server will be started back up and will be available shortly after. Players will have to know to wait a minute after the first connection fails and to try again if the server had been sleeping.
 
-This is using the docker image found at https://hub.docker.com/r/mbround18/valheim
+Override the timer value at `world_sleep_timer` (default 60 minutes). Set to an unrealistically high number to disable.
