+## Large File Storage
+
+[Data Version Control](https://dvc.org) is the system for large file storage in this super-repo. It provides staging capabilities on top of what Git LFS typically provides that ROCm CI/CD workflows can make use of. Files are stored in an AWS S3 bucket that has public-read access.
+
+Currently, `dvc` utilization is limited to the `pal` libraries in the `shared/amdgpu-windows-interop` directory.
+If your development does not involve these files, you do not need to install `dvc`.
+
+### Installing DVC
+
+`dvc` can be installed as a python module via pip and is cross-platform. Visit the [dvc installation page](https://dvc.org/doc/install) if you want to use another method of installation. Due to our use of an AWS S3 bucket with `dvc`, the `dvc[s3]` module should be installed. The configuration to download the large files from the AWS S3 bucket is already set in this repository.
+
+```bash
+pip install dvc[s3]
+```
+
+### Retrieving large files:
+
+```bash
+git pull
+dvc pull
+```
+
+### Switching to versions in other branches or commits:
+
+```bash
+git checkout feature-branch
+dvc checkout
+```
+
+### Update large files
+
+Write-access requires authentication. Please reach out to a project lead for credentials. To make updates to files maintained by `DVC`:
+
+```bash
+dvc add [path-to-large-file-modified]
+dvc push
+git status
+git add [dvc-files-mentioned-from-status-output]
+git commit -m "commit message"
+git push
+```

 ## Gardener Rotation
 
 In order to achieve the goal of keeping the `develop` branch healthy, a team of ROCm engineers will be dedicated towards monitoring and triaging issues that arise.
