+## Extraction Instructions
+The archives are compressed using `zstd` for fast decompression. To extract the dataset, you need to have `zstd` installed. You can install it via package managers like `apt`, `brew`. 
+
+**To extract an archive, use the following command:**
+```bash
+tar --use-compress-program=zstd -xf [archive_file.tar.zst]
+```
+
+**To extract all archives in a directory, you can use:**
+```bash
+for archive in *.tar.zst; do
+    echo "Extracting $archive..."
+    tar --use-compress-program=zstd -xf "$archive"
+done
+```
