@@ -61,6 +61,11 @@ The benchmarking framework supports:
 - Customizable concurrency levels (configurable via CONCURRENCIES env var), sequence lengths, and models
 - Automated performance plot generation with custom labels
 
+**Sequential GPU Usage:**
+- Models are deployed and benchmarked **sequentially**, not in parallel
+- Each deployment gets exclusive access to all available GPUs during its benchmark run
+- Ensures accurate performance measurements and fair comparison across configurations
+
 **Supported Backends:**
 - DynamoGraphDeployments
 - External HTTP endpoints (for comparison with non-Dynamo backends)

+#### Path Requirements
+
+**Important**: The PVC is mounted at `/data` in the access pod for security reasons. All destination paths must start with `/data/`.
+
+**Common path patterns:**
+- `/data/configs/` - Configuration files (DGD manifests)
+- `/data/results/` - Benchmark results
+- `/data/profiling_results/` - Profiling data
+- `/data/benchmarking/` - Benchmarking artifacts
+
+**User-friendly error messages**: If you forget the `/data/` prefix, the script will show a helpful error message with the correct path and example commands.
