+## Purpose
+If you want to deploy the FOG Project software in your homelab environment to remotely image devices via PXE boot, follow the instructions below to get through the process.
+
+!!! info "assumptions"
+    It is assumed that you are deploying FOG Project in Ubuntu Server 26.04 or newer.  This documentation does not account for distro-specific issues in other operating systems.
+
+    It is also assumed that you allocate at least 4-cores and 8GB of RAM with at least 256GB of storage for the OS and FOG images.
+
+!!! warning "Potential Netplan Misconfiguration"
+    I observed an oddity with the networking stack of the Ubuntu Server VM, so just to be safe, run the following command to check that you have both the `nameservers` pointing to your DNS server(s) and `routes` pointing to your default gateway.
+
+    ```sh
+    cd /etc/netplan
+    ls
+    <look for the netplan file>
+    nano <netplan file>
+    ```
+
+    Ensure it looks something like this, and fix it if any fields are missing:
+
+    ```yaml
+    network:
+      ethernets:
+          ens18:
+          addresses:
+          - 192.168.3.9/24
+          routes:
+              - to: default
+              via: 192.168.3.1
+          match:
+              macaddress: bc:24:11:5c:eb:c9
+          nameservers:
+              addresses: [192.168.3.25, 192.168.3.26]
+              search: []
+          set-name: ens18
+      version: 2
+    ```
+
+    Lastly run `sudo netplan apply` to apply the changes to fix the networking stack.
