 `ai-hub upload` runs the four Workbench upload steps in order: quantize, compile, validate, and profile. Use `--from-step compile`, `--from-step validate`, or `--from-step profile` to resume from saved local state after a completed earlier step.
 
+Resume behavior:
+
+```text
+--from-step quantize  Run quantize, compile, validate, and profile.
+--from-step compile   Skip quantize; compile the last quantized model unless an explicit source is passed.
+--from-step validate  Skip quantize and compile; validate the last compiled model.
+--from-step profile   Skip quantize, compile, and validate; profile the last compiled model.
+```
+
+When a step runs in the current command, `upload` passes its returned model ID directly to the next step. When a step is skipped, the next step resolves the needed model ID from `.qc-cli.json`. This avoids re-running earlier AI Hub jobs when you only need to continue from a later step.
+
 `ai-hub compile` resolves model sources in this order: `--model-id`, explicit source options (`--onnx-path`, `--model-s3-uri`, `--from-job`), last quantized model from state, then the last training job from local state. `ai-hub download` is separate because downloading the optimized artifact is outside the four-step Workbench upload loop.
 
 AI Hub authentication currently uses the local `qai-hub` SDK configuration. A planned follow-up is to support AWS Systems Manager Parameter Store `SecureString` for team-managed tokens, where `config.yaml` stores only a parameter name such as `/qc-cli/aihub/token`, AWS KMS encrypts the token at rest, and the CLI retrieves it at runtime with `ssm:GetParameter` plus `kms:Decrypt` permissions.

+## Upload Model to Qualcomm Workbench
+
+The model can be uploaded to Qualcomm Workbench using:
 
 ```bash
-uv run python examples/ai-hub/prepare_inputs.py \
+qc-cli ai-hub upload examples/training/data/aihub_calibration examples/training/data/inputs.npz
-  --dataset-dir examples/training/data/flower_photos_sagemaker \

-  --input-file examples/training/data/inputs.npz \
-  --samples 16
 ```
 
-## Run AI Hub
+The first argument is the calibration path for the model and the second argument is the input file, both of which were created by the `prepare_inputs.py` script. For more details, add `--help` after the `upload` command.
 
-After training completes and inputs are prepared:
+The `upload` command runs the following commands in order:
+1. `qc-cli ai-hub quantize`
+2. `qc-cli ai-hub compile`
+3. `qc-cli ai-hub validate`
+4. `qc-cli ai-hub profile`
 
+Finally the user can download the model from AI Workbench using the command
 ```bash
-bash examples/ai-hub/run_ai_hub.sh --config config.yaml
+qc-cli ai-hub download
 ```
-
-By default, the script uses the last SageMaker training job recorded in `.qc-cli.json`. It downloads that job's `model.tar.gz`, extracts `model.onnx`, runs the AI Hub workflow, and downloads the compiled artifact.
-
-To use a specific training job:
-
-```bash
-bash examples/ai-hub/run_ai_hub.sh \
-  --config config.yaml \
-  --from-job qc-cli-YYYYMMDD-HHMMSS
-```
-
-To resume from a later Workbench step:
-
-```bash
-bash examples/ai-hub/run_ai_hub.sh \
-  --config config.yaml \
-  --from-step validate
-```
-
-To skip downloading the compiled artifact:
-
-```bash
-bash examples/ai-hub/run_ai_hub.sh \
-  --config config.yaml \
-  --skip-download
-```
-
-## Troubleshooting
-
-If AI Hub reports dynamic input shapes, rerun training with the current training source. AI Hub quantization requires the exported ONNX model to use static input shapes.
-
-If `run_ai_hub.sh` reports missing calibration or input files, run:
-
-```bash
-uv run python examples/ai-hub/prepare_inputs.py
-```
-
-If validation fails with a missing input name, make sure `config.yaml` and the generated `.npz` both use `input` as the input name.
