+## Prerequisites\n\

+   sudo apt install rocm-dev hip-runtime-amd\n\
+\n\
+2. Install ROCm kernel modules (if not already installed):\n\
+   sudo apt install rocm-dkms\n\
+\n\
+## Integration Steps\n\
+\n\
+1. Copy the shared library:\n\
+   sudo cp librinhash_hip.so /usr/local/lib/\n\
+   sudo ldconfig\n\
+\n\
+2. Test ROCm support:\n\
+   ./test-rocm.sh\n\
+\n\
+3. For cpuminer integration:\n\
+   - Copy include files to your build system\n\
+   - Link against librinhash_hip.so\n\
+   - Use HIP runtime functions for GPU acceleration\n\
+\n\
+## Usage Example\n\
+```c\n\
+#include "rinhash_device.cuh"\n\
+\n\
+// Initialize HIP\n\
+hipInit(0);\n\
+\n\
+// Call RinHash GPU function\n\
+rinhash_cuda(input, input_len, output);\n\
+```\n\
