+
+# Getting Started
+
+This template is designed to be installed inside a Codio box. To to this, open the terminal and run the following command:
+
+```
+$ curl -sL https://bit.ly/3yKYBTg | bash
+```
+
+This will configure the box ready for you to start development.
+
+> The process can take up to 15 min. Make sure you don't close the browser tab _or let your computer go into sleep mode_.
+
+To run the server:
+
+```shell
+$ deno run --allow-all --unstable index.js
+```
+
+The website database has been added with a root password of `p455w0rd` and a single **accounts** table which is pre-configured with a single account:
+
+username: `doej`
+
+password: `p455w0rd`
+
+There is a secure page called **Foo Bar** which can be accessed at the `/foo` route. You will need to delete this and replace with your own secure content.

+
+## Pushing to GitHub
+
+If you can't push to the University GitHub server (you are not prompted for the username/password and the connection times out) please run the following command which will print the Codio box external IP address and send this to your module leader.
+
+```
+$ dig +short myip.opendns.com @resolver1.opendns.com
