 ## Download Instructions
 
+1. Download the *manifet.json* file and *chapter.json* files corresponding to your desired sampling rate from this Hugging Face repository. Copy these into a workspace directory (in this example */home/hifitts2*).
+2. Install NeMo-speech-data-processor (SDP) using the *Installation* instructions on https://github.com/NVIDIA/NeMo-speech-data-processor.
+3. Run the SDP script to download the dataset to local disk.
+
+```bash
+python /home/NeMo-speech-data-processor/main.py \
+    --config-path="/home/NeMo-speech-data-processor/dataset_configs/english/hifitts2" \
+    --config-name="config_22khz.yaml" \
+    workspace_dir="/home/hifitts2" \
+    max_workers=8
+```
+
+*max_workers* is the number of threads to use for downloading the data. To download the 44khz dataset, specify *config_44khz.yaml*.
+
+By default, the script will download audio files into the workspace directory under *{workspace_dir}/audio_22khz*. The download will ignore HTTP errors and store information for any failed downloads into *{workspace_dir}/errors_22khz.json*. A new manifest will be created at *{worksapce_dir}/manifest_filtered_22khz.json* with utterances from failed audiobooks removed. You can override the default behavior by modifying the *config.yaml* file in your local SDP repository [TODO: Add link to config fil;e].
+
+If you want to retry the download for failed audiobooks, rerun the script with the output *errors_22khz.json* file. 
+
+```bash
+python /home/NeMo-speech-data-processor/main.py \
+    --config-path="/home/NeMo-speech-data-processor/dataset_configs/english/hifitts2" \
+    --config-name="config_22khz.yaml" \
+    workspace_dir="/home/hifitts2" \
+    chapter_filename="/home/hifitts2/chapters_22khz.json" \
+    max_workers=8
+```
+
+Due to legal and ethical considerations, we do not redistribute LibriVox audiobooks to download from Hugging Face.
