-According to the [Internet Security Glossary](https://www.rfc-editor.org/rfc/rfc4949), an Air Gap is an interface between two systems at which (a) they are not connected physically and (b) any logical connection is not automated (i.e., data is transferred through the interface only manually, under human control). 
+To get underway open your web browser and navigate to the workshop login page https://demo.redhat.com/workshop/enwmgc.

+## 1.2 - Opening your web terminal
+
+Throughout the remainder of the workshop you will be using a number of command line interface tools for example, `aws` to quickly interact with resources in Amazon Web Services, and `ssh` to login to a remote server.
+
+To save you from needing to install or configure these tools on your own device for the remainder of this workshop a web terminal will be available for you.
+
+Simply copy the link below and paste into your browser, replacing `<number>` with the three digit number in the top level route53 domain obtained in the aws environment details assigned in the previous step.

+## 1.3 - Creating an air gap
+
+According to the [Internet Security Glossary](https://www.rfc-editor.org/rfc/rfc4949), an Air Gap is:
+
+> "an interface between two systems at which (a) they are not connected physically and (b) any logical connection is not automated (i.e., data is transferred through the interface only manually, under human control)." 
 
 In disconnected OpenShift installations, the air gap exists between the **Low Side** and the **High Side**, so it is between these systems where a manual data transfer, or **sneakernet** is required.
 
-For the purposes of this workshop we will be operating within Amazon Web Services. You will be allocated an environment that already has AWS credentials configured and has some basic preparation completed. This will be a single VPC with 3 public subnets, which will serve as our **Low Side**, and 3 private subnets, which will serve as our **High Side**.
