 This directory contains sample implementations of training and evaluation pipelines for a Conformer RNN-T ASR model.
 
+## Setup
+### Install PyTorch and TorchAudio nightly or from source
+Because Conformer RNN-T is currently a prototype feature, you will need to either use the TorchAudio nightly build or build TorchAudio from source. Note also that GPU support is required for training.
+
+To install the nightly, follow the directions at <https://pytorch.org/>.
+
+To build TorchAudio from source, refer to the [contributing guidelines](https://github.com/pytorch/audio/blob/main/CONTRIBUTING.md).
+
+### Install additional dependencies
+```bash
+pip install pytorch-lightning sentencepiece
+```
+
 ## Usage
 
 ### Training
 
-[`train.py`](./train.py) trains an Conformer RNN-T model (30.2M parameters, 121MB) on LibriSpeech using PyTorch Lightning. Note that the script expects users to have access to GPU nodes for training and provide paths to the full LibriSpeech dataset and the SentencePiece model to be used to encode targets.
+[`train.py`](./train.py) trains an Conformer RNN-T model (30.2M parameters, 121MB) on LibriSpeech using PyTorch Lightning. Note that the script expects users to have the following:
+- Access to GPU nodes for training.
+- Full LibriSpeech dataset.
+- SentencePiece model to be used to encode targets; the model can be generated using [`train_spm.py`](./train_spm.py)
+- File (--global_stats_path) that contains training set feature statistics; this file can be generated using [`global_stats.py`](../emformer_rnnt/global_stats.py).
