+### Debian-based systems
+
+If you're using an Operating System such as Ubuntu or Debian , you can use our official Debian package to install OpenFaaS Edge.
+
+Download it on a machine with Internet access, transfer it to the air-gapped machine, and install it using:
+
+```bash
+arkade oci install --path . ghcr.io/openfaasltd/faasd-pro-debian:latest
+```
+
+If you wish to obtain a specific version of the package, update the tag from `:latest` to i.e. `:0.2.18`. Browse available versions via `crane ls ghcr.io/openfaasltd/faasd-pro-debian`.
+
+Then copy all `openfaas-edge-*.deb` files to the air-gapped machine.
+
+Before installing OpenFaaS Edge ensure all other required packages are installed on the air-gapped system:
+
+```sh
+sudo apt-get install runc bridge-utils iptables iptables-persistent
+```
+
+If you have no way to source the required packages in the offline environment, you can download them on an online machine with tools like e.g [apt-offline](https://github.com/rickysarraf/apt-offline/wiki) and copy them to the air-gapped machine.
+
+Install the OpenFaaS Edge package:
+
+```sh
+sudo apt-get install ./openfaas-edge-*.deb
+```
+
+After the installation completes add you OpenFaaS Edge license:
 
 ```sh
-sudo faasd install --dns-server 127.0.0.53
+sudo mkdir -p /var/lib/faasd/secrets
+sudo nano /var/lib/faasd/secrets/openfaas_license
 ```
 
-Make sure to also add `--pull-policy=IfNotPresent` when images were restored directly to the containerd library. This is not required when using a local image registry.
+The final installation step sets up and starts the faasd and faasd-provider services.
+
+If you have a custom DNS server available, specify it using the `--dns-server` flag:
+
+```sh
+--dns-server 10.0.0.1
+```
+
+If there is no DNS available, you can point faasd at the local host to use systemd-resolved:
+
+```sh
+--dns-server 127.0.0.53
+```
+
+If your images are restored to the containerd library, you will have to use the `--pull-policy=IfNotPresent` flag to prevent faasd from trying to pull the images from the Internet.
+
+```sh
+--pull-policy=IfNotPresent
+```
+
+Finally, construct the command to install OpenFaaS Edge:
+
+Example with no DNS server, and images restored to the containerd library:
+
+```sh
+sudo faasd install \
+  --dns-server 127.0.0.53 \
+  --pull-policy=IfNotPresent
+```
+
+Example with custom DNS server, and a remote registry:
+
+```sh
+sudo faasd install \
+  --dns-server 10.0.0.1
+```
