+## Uploading models via the S3-compatible API
+
+You can upload models to your network volume using RunPod’s [S3-compatible API](https://docs.runpod.io/storage/s3-api). You need an **S3 API key** (separate from your RunPod API key): create one under **Settings → S3 API Keys** in the RunPod console. The access key and secret are shown there; the docs explain [setup and authentication](https://docs.runpod.io/storage/s3-api#setup-and-authentication) in detail.

+```bash
+AWS_ACCESS_KEY_ID=your_access_key \
+AWS_SECRET_ACCESS_KEY=your_secret_key \
+aws s3 cp \
+  --region [REGION] \
+  --endpoint-url ENDPOINT_URL \
+  /path/to/local/file.ext \
+  s3://BUCKET_NAME/models/[model]/file_name.ext
+```
+
+The file will then appear at `/runpod-volume/models/[model]/file_name.ext` inside the worker.

 ComfyUI only recognizes files with specific extensions when scanning model directories.

 If any of the above is true, ComfyUI will silently fail to discover models from the network volume.
 
+### Tests and `runpod-volume` access
+
+RunPod’s test environment does **not** have access to the network volume mount: the `/runpod-volume` folder is not visible when tests run. When the endpoint starts for real, the volume is mounted and the folder appears. The repository ships with the tests file renamed to `.runpod/tests_.json` so they don't run by default; if you've re-enabled them and they fail with `Value not in list`, remove or rename the file again so the endpoint is deployed without running those tests.

 ## Debugging with `NETWORK_VOLUME_DEBUG`
 
 The worker exposes an opt‑in debug mode controlled via the `NETWORK_VOLUME_DEBUG` environment variable.
