+## Installation via FreeBSD Ports (Custom Overlay)
+
+The project is packaged for FreeBSD through a dedicated, standalone ports
+repository overlay. If you manage a local ports overlay or want to build a
+clean native package via `poudriere`/`bmake`, add the port definition from
+the tracking tree repository:
+
+* **Ports Overlay Repository**: [https://git.dc365.ru/digital-freak/ports](https://git.dc365.ru/digital-freak/ports)
+
+To build and install the toolkit from the overlay manually:
+
+```bash
+# Navigate to the port directory inside your overlay tree
+cd /usr/ports/devel/bsdiskinfo
+
+# Configure, build, and install with selected bindings (Lua/Perl)
+sudo make config
+sudo make install clean
+```
+
