+# GetV4: Self-Hosted Check IP Service
+
+This will allow you to obtain your WAN IPv4 address from pfSense in a manner similar to most Check IP webpages. It's
+output is simply just the IP address with no additional text. It will only return your machine's IPv4 and is not a 
+public check IP service.
+
+This is the same as the version included in HEDyn.
+
+It is not strictly for pfSense and will work on any machine with a public v4 and php.
+
+## Installation
+
+- Modify `getv4.sh` with the interface name of your WAN device.
+- Modify `getv4.php` with the path to `getv4.sh`
+- Load getv4.php in your browser.
+
+In pfSense installations, this directory is `/usr/local/www`
