+## How to Download
+
+We highly recommend downloading each dataset (`.tar`) file separately:
+
+```bash
+# Example: Download GQA
+huggingface-cli download SNUMPR/HFLB GQA.tar \
+    --local-dir ./ \
+    --repo-type dataset
+
+# Example: Download AQUA
+huggingface-cli download SNUMPR/DRAKE AQUA.tar \
+    --local-dir ./ \
+    --repo-type dataset
+```
+
+After downloading, extract each archive:
+```bash
+tar -xvf AQUA.tar
+# Repeat for other archives
+```
+
+Place extracted data under the `dataset/` folder in the [code repository](https://github.com/snumprlab/fedmosaic), following the structure described in the [README](https://github.com/snumprlab/fedmosaic/blob/main/README.md).
