+Docker compose is configured to run the node on a local machine on port 80. If you would like to run the node on different
+port you will need to change the `docker-compose.yml` to
 
     ports:
-        - "80:3000"
+        - "<your-port>:3000"
 
 This way the node will be accessible via port 80.
 
 Or you can use a reverse proxy like NGINX to make the node publicly available. This is highly recommended. 
 
+Run on EC2 
+---
+
+To Run the not on a AWS EC2 instance we have included an install script will bootstrap your ec2 instance. To use this script
+you will need to select the following AMI: ami-c91624b0.
+
+So to run a node on a EC2 instance you can perform the following steps:
+
+1. Click "Launch Instance" and select ami-c91624b0 from the 'Community AMIs'
+2. Select an instance type, currently a t2.micro is sufficient.
+3. Configure instance, here 2 things are important.
+  - The node requires a public ip
+  - Under the "Advanced Details" tab you need to upload the provided `install_ec2.sh` file (this will installed the node)
+4. Adding storage is different depending on whether you will run an external mongo service. If you choose the default, select
+atleast 15 Gb of storage.
+5. For the security group make sure the node can be accessed on port 80
+6. You are ready to run launch the instance.
