 ### Get ExecuTorch Program Pointer from `BundledProgram` Buffer
 We need the pointer to ExecuTorch program to do the execution. To unify the process of loading and executing `BundledProgram` and Program flatbuffer, we create an API for this
-`executorch::bundled_program::get_program_data`. Check out an [example usage](https://github.com/pytorch/executorch/blob/release/0.6/examples/devtools/example_runner/example_runner.cpp#L128-L137) of this API.

 ### Load Bundled Input to Method
-To execute the program on the bundled input, we need to load the bundled input into the method. Here we provided an API called `executorch::bundled_program::load_bundled_input`.  Check out an [example usage](https://github.com/pytorch/executorch/blob/release/0.6/examples/devtools/example_runner/example_runner.cpp#L253-L259) of this API.

 ### Verify the Method's Output.
-We call `executorch::bundled_program::verify_method_outputs` to verify the method's output with bundled expected outputs. Check out an [example usage](https://github.com/pytorch/executorch/blob/release/0.6/examples/devtools/example_runner/example_runner.cpp#L300-L311) of this API.

 ### Runtime Example
 
 Please checkout our [example runner](https://github.com/pytorch/executorch/blob/release/0.6/examples/devtools/README.md#bundledprogram) for a bundled program. You could run these commands to test with the BundledProgram binary (`.bpte`) file you generated in the previous step:
 
 ```bash
 cd executorch
-   ./examples/devtools/build_example_runner.sh
-   ./cmake-out/examples/devtools/example_runner --bundled_program_path {your-bpte-file} --output_verification
+./examples/devtools/build_example_runner.sh
+./cmake-out/examples/devtools/example_runner --bundled_program_path {your-bpte-file} --output_verification
 ```
 
 It is expected to see no output from running the above mentioned snippet.
+For a detailed example of how the runner should be like, please refer to our [example runner](https://github.com/pytorch/executorch/blob/release/1.0/examples/devtools/example_runner/example_runner.cpp).

+### Try the Complete Workflow
+
+To test the entire end-to-end workflow including building the example runner, exporting a model, and verifying the bundled program execution, you can use the test script:
+
+```bash
+cd executorch
+./examples/devtools/test_example_runner.sh
+```
+
+This script will:
+1. Build the example runner using `build_example_runner.sh`
+2. Export a MobileNetV2 model as a bundled program
+3. Run the example runner with the bundled program to verify correctness
+
+This is a great way to ensure your environment is set up correctly and to see the complete BundledProgram workflow in action.
