+## Requirements
 
-## Requirements:
+### You need a Server/VM
 
-### You need a Server/VM:
 - Option #1 - A cloud server that is either debian/ubuntu. You can use [AWS](https://cde.glueops.dev) or [Hetzner](https://www.hetzner.com/) or any other cloud. It's recommended you have at least 16GB of RAM but 32-64GB would be optimal.
 - Option #2 - Proxmox. (Recommended)
 
 ### Getting setup
+
 - Login to your server using whatever method you like (SSH or password is fine) but you must login with a root or a user that has sudo access.
 - Run:
+
   ```bash
   #If you are using proxmox you will not be able to do copy/paste in the web ssh console.
   bash <(curl -sL setup.glueops.dev)
   ```
+
 - Once you finish following the prompts and the server reboots, you will need to connect to it using your private ssh key with the `glueops` username. If you are using proxmox the username is `root` and you will need to switch to `glueops` using: `su - glueops`
 - Once logged in as the `glueops` user, type `cd` so that you are in `/home/glueops` and then just run `dev` and select the version you want (newest is recommended) and go ahead and get started to get a code tunnel/space going.

-### Creating your cluster.
+### Creating your cluster
 
 - `cd` into your _captain_ directory
 - Run:
+
 ```bash
-curl https://raw.githubusercontent.com/GlueOps/k3d/main/k3d-config.yaml -o k3d-config.yaml && k3d cluster create --config k3d-config.yaml
+curl https://raw.githubusercontent.com/GlueOps/k3d/main/k3d-config.yaml -o k3d-config.yaml && k3d cluster create --config k3d-config.yaml && bash <(curl -sL https://raw.githubusercontent.com/GlueOps/k3d/main/add-machineid.sh)
 ```
+
 - Using our **lightsail AWS account** run this from a cloudshell session:
+
 ```bash
 bash <(curl -s https://raw.githubusercontent.com/GlueOps/development-only-utilities/main/tools/aws/lightsail.sh)
 ```
+
 - Take the output from the lightsail creation and run it against your k3s cluster.
 - Continue with the rest of the docs in your captain README.md
