+### Split-tunnel usage
+If you only want to tunnel specific subnets through the VPN-tunnel, you can enable Split-tunnel configuration by passing the TUNNEL_CIDR_BLOCKS environment variable. For example, if you want to tunnel just the subnets 10.0.1.0 with netmask 255.255.255.0 and 10.0.2.0 with netmask 255.255.255.0, you specify 10.0.1.0/24 and 10.0.2.0/24:
+
+On the command line:
+```bash
+TUNNEL_CIDR_BLOCKS=(10.0.1.0/24 10.0.2.0/24) ./openvpn-install.sh
+```
+On in a script:
+```bash
+#!/bin/bash
+export TUNNEL_CIDR_BLOCKS="10.0.1.0/24 10.0.2.0/24"
+./openvpn-install.sh
+```
+_Notes:_
+- _Currently only 8-, 16-, 24- and 32-bits subnets are supported!_
+- _/bin/sh doesn't support array's, so bash is required._
