 # usb-crash-cart
+
+Docker container wrapper for the NOTECONS02 USB Crash Cart Adapter software.
+
+The vendor software (`usb-crash-cart-adapter` v20240517) was built against Ubuntu 16.04
+(Python 2.7, wxWidgets 2.9/GTK2) and is incompatible with modern Fedora. This repo runs
+it inside an Ubuntu 16.04 container with X11 passthrough.
+
+## Setup
+
+### 1. Install udev rules (once, on the host)
+
+```bash
+sudo ./install-udev-rules.sh
+```
+
+This allows the crash cart adapter (USB vendor `152a`, products `8460`/`8463`) to be
+accessed without root.
+
+### 2. Place the .deb package
+
+Copy the vendor `.deb` to `packages/crash-cart.deb`:
+
+```bash
+cp /path/to/"Linux-X64 Crash Cart Software_1240415.deb" packages/crash-cart.deb
+```
+
+### 3. Build the image
+
+```bash
+docker build -t usb-crash-cart .
+```
+
+### 4. Run
+
+```bash
+./docker-run.sh
+```
+
+This handles X11 socket sharing and USB device passthrough automatically.
+
+## Notes
+
+- The container uses `ubuntu:16.04` to match the build environment.
+- The app bundles its own `libpython2.7`, `libwx_gtk2u-2.9`, `libpng12`, etc. — the
+  container only needs GTK2 and X11 system libs from the OS.
+- `LD_LIBRARY_PATH` is set to prefer the bundled libs over system ones.
+- The `.deb` is excluded from git (`.gitignore`) — obtain it from the vendor package.
