 2. Development
-  1. Provision the test VMs:
-    ```bash
-    > vagrant up
-    ```
-  2. Start the WireGuard™ interface on the server:
-    ```bash
-    > vagrant ssh server
-    # ... wait for SSH session to establish, then
-    > sudo wg-quick up wg0
-    ```
-    You should see output like:
-    ```
-    [#] ip link add wg0 type wireguard
-    [#] wg setconf wg0 /dev/fd/63
-    [#] ip -4 address add 192.168.10.1/24 dev wg0
-    [#] ip link set mtu 1420 up dev wg0
-    [#] iptables -A FORWARD -i wg0 -j ACCEPT; iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE; ip6tables -A FORWARD -i wg0 -j ACCEPT; ip6tables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
-    ```
-  3. Start the WireGuard interface on the client:
-    ```bash
-    > vagrant ssh client
-    # ... wait for SSH session to establish, then
-    > sudo wg-quick up wg0
-    ```
