+### Installing to USB Drive
+
+Once you have created the `sparkos.img` file, use the installation script to write it to a USB drive or storage device:
+
+```bash
+# Use the installation script (RECOMMENDED)
+sudo ./scripts/install.sh /dev/sdX
+
+# The script will:
+# - Validate the target drive
+# - Display warnings about data destruction
+# - Require confirmation before proceeding
+# - Show progress during installation
+# - Verify successful installation
+```
+
+Replace `/dev/sdX` with your actual USB device (e.g., `/dev/sdb`, `/dev/nvme1n1`).
+
+**⚠️ WARNING**: This will permanently erase all data on the target drive!
