 ## Overview
 
-This notebook provides scripts for you to run Jasper with TRT for inference step by step. You can run inference using either LibriSpeech dataset or your own audio input in .wav format, to generate the corresponding text file for the audio file. 
+This notebook provides scripts for you to run Jasper with TRT for inference step by step. You can run inference using either LibriSpeech dataset or your own audio input in .wav format, to generate the corresponding text file for the audio file.
 
 ## Requirements
 
 This repository contains a Dockerfile which extends the PyTorch 19.09-py3 NGC container and encapsulates some dependencies. Aside from these dependencies, ensure you have the following components:
-    
-* [NVIDIA Docker](https://github.com/NVIDIA/nvidia-docker)
-* [PyTorch 19.09-py3 NGC container](https://ngc.nvidia.com/catalog/containers/nvidia:pytorch)
-* [NVIDIA Turing](https://www.nvidia.com/en-us/geforce/turing/) or [Volta](https://www.nvidia.com/en-us/data-center/volta-gpu-architecture/) based GPU
-* [Pretrained Jasper Model Checkpoint](https://ngc.nvidia.com/catalog/models/nvidia:jasperpyt_fp16)
+
+-    NVIDIA Docker
+-    PyTorch 19.09-py3 NGC container
+-    NVIDIA Turing or Volta based GPU
+-    Pretrained Jasper Model Checkpoint
 
 ## Quick Start Guide
 
 Running the following scripts will build and launch the container containing all required dependencies for both TensorRT as well as native PyTorch. This is necessary for using inference with TensorRT and can also be used for data download, processing and training of the model.
 
-1. Clone the repository.
+#### 1. Clone the repository.
 
-```bash
+```
 git clone https://github.com/NVIDIA/DeepLearningExamples
 cd DeepLearningExamples/PyTorch/SpeechRecognition/Jasper
 ```
-2. Build the Jasper PyTorch with TRT 6 container:
 
-```bash
+#### 2. Build the Jasper PyTorch with TRT 6 container:
+
+```
 bash trt/scripts/docker/trt_build.sh
 ```
-3. Prepare to start a detached session in the NGC container
+
+#### 3. Create directories
+Prepare to start a detached session in the NGC container.
 Create three directories on your local machine for dataset, checkpoint, and result, respectively, naming "data" "checkpoint" "result":
 
-```bash
+```
 mkdir data checkpoint result
 ```
-Download the checkpoint file `jasperpyt_fp16` to the directory `checkpoint` from NGC Model Repository: https://ngc.nvidia.com/catalog/models/nvidia:jasperpyt_fp16
-Assume you will download the dataset to /dev/sdb and mount the data on /dev/sdb to "data", please replace "/dev/sdb" with your own directories if you use other directories:
 
-```bash
-sudo mount /dev/sdb data
-```
-The Jasper PyTorch container will be launched in the Jupyter notebook. Within the container, the contents of the root repository will be copied to the /workspace/jasper directory. The /datasets, /checkpoints, /results directories are mounted as volumes and mapped to the corresponding directories "data" "checkpoint" "result" on the host.
+#### 4. Download the checkpoint
+Download the checkpoint file jasperpyt_fp16 from NGC Model Repository:  
+- https://ngc.nvidia.com/catalog/models/nvidia:jasperpyt_fp16
+
+to the directory: _checkpoint_
+
+The Jasper PyTorch container will be launched in the Jupyter notebook. Within the container, the contents of the root repository will be copied to the /workspace/jasper directory.
 
-Copy the JasperTRT.ipynb notebook to the root directory of Jasper:
-```bash
+The /datasets, /checkpoints, /results directories are mounted as volumes and mapped to the corresponding directories "data" "checkpoint" "result" on the host.
+
+#### 5. Copy the notebook to the root
+
+Copy the notebook to the root directory of Jasper:
+
+```
 cp notebooks/JasperTRT.ipynb .
 ```
 
+#### 6. Run the notebook
 For running the notebook on your local machine, run:
 
-```bash
+```
 jupyter notebook JasperTRT.ipynb
 ```
-For running the notebook on another machine remotely, run: 
 
-```bash
+For running the notebook on another machine remotely, run:
+
+```
 jupyter notebook --ip=0.0.0.0 --allow-root
 ```
-And navigate a web browser to the IP address or hostname of the host machine at port 8888: http://[host machine]:8888
