 > **Note:** Unlike the `.deb` and `.rpm` packages, the tar.gz installation requires manual setup of the PC/SC daemon. If you see "No readers found", ensure `pcscd` is running (`systemctl status pcscd`).
 
+**Atomic Linux Distributions (Fedora Silverblue, Kinoite, etc.) with Distrobox:**
+
+For immutable/atomic distributions, you can run NFC Agent inside a distrobox container while applying kernel fixes on the host OS:
+
+1. **On the host OS** - Apply the kernel module blacklist (required for ACR122U and similar readers):
+   ```bash
+   # Create blacklist file on the host
+   echo -e "blacklist pn533_usb\nblacklist pn533\nblacklist nfc" | sudo tee /etc/modprobe.d/blacklist-pn533.conf
+
+   # Unload modules if currently loaded
+   sudo modprobe -r pn533_usb pn533 nfc 2>/dev/null || true
+
+   # Restart PC/SC daemon on host
+   sudo systemctl restart pcscd
+   ```
+
+2. **Inside distrobox** - Install the package:
+   ```bash
+   # Enter your distrobox container (e.g., Fedora-based)
+   distrobox enter fedora
+
+   # Install the RPM package
+   sudo dnf install ./NFC-Agent-*.rpm
+   ```
+
+3. **Run from distrobox** - Start NFC Agent from within the container:
+   ```bash
+   distrobox enter fedora
+   nfc-agent
+   ```
+
+> **Note:** The kernel module blacklist must be applied on the host OS because the kernel is shared between the host and containers. The pcscd service also runs on the host and is accessible from within distrobox.

 ## Quick Start
 
 1. **Connect** your NFC reader via USB
