+# RinHash ROCm GPU Direct Integration
+
+This build uses the existing `cpuminer-rocm-build` container to avoid dependency issues.
+
+## Files Created
+
+### GPU Libraries (`gpu-libs/`)
+- `librinhash_hip.so` - Shared library for GPU acceleration
+- `*.cuh` - Header files for GPU functions
+
+## Usage
+
+### 1. Copy GPU library to system
+```bash
+sudo cp gpu-libs/librinhash_hip.so /usr/local/lib/
+sudo ldconfig
+```
+
+### 2. For cpuminer integration
+Modify your cpuminer RinHash implementation to use GPU functions:
+
+```c
+#include <dlfcn.h>
+
+// Load GPU library
+void* gpu_lib = dlopen("librinhash_hip.so", RTLD_LAZY);
+if (gpu_lib) {
+    // Use GPU functions
+    rinhash_cuda_function = dlsym(gpu_lib, "rinhash_cuda");
+}
+```
+
+### 3. Build cpuminer with GPU support
+```bash
+./configure CFLAGS="-O3 -march=native"
+make -j$(nproc)
+```
+
+## Testing
+
+Test GPU support:
+```bash
+rocm-smi  # Check GPU availability
+```
+
+Test library loading:
+```bash
+ldd librinhash_hip.so
+```
