 ## Quick Start
 
-Download the dataset with:
+Download the dataset:
 ```shell
 hf download ibm-esa-geospatial/ImpactMesh-Flood --repo-type dataset --local-dir data/ImpactMesh-Flood
 
 # Only download a single modality (e.g., S2L2A)
-hf download ibm-esa-geospatial/ImpactMesh-Flood --repo-type dataset --include "data/S2L2A*.tar" --local-dir data/ImpactMesh-Flood
+hf download ibm-esa-geospatial/ImpactMesh-Flood --repo-type dataset --include "*/S2L2A.tar" --local-dir data/ImpactMesh-Flood
+
+# Only download a single split (e.g., validation)
+hf download ibm-esa-geospatial/ImpactMesh-Flood --repo-type dataset --include "val/*" --local-dir data/ImpactMesh-Flood
+```
+
+Untar the samples:
+```shell
+mkdir data/ImpactMesh-Flood/data
+for f in data/ImpactMesh-Flood/*/*.tar; do
+  echo "Extracting $f"
+  tar -xf "$f" -C data/ImpactMesh-Flood/data
+done
 ```
 
-Untar the samples with:
+The samples from all splits are saved in shared folders `data/ImpactMesh-Flood/data/{modality}`. After extracting, you can delete the tars:
 ```shell
-tar -xf data/ImpactMesh-Flood/data/S2L2A_1.tar -C data/ImpactMesh-Flood/data
-tar -xf data/ImpactMesh-Flood/data/S2L2A_2.tar -C data/ImpactMesh-Flood/data
-tar -xf data/ImpactMesh-Flood/data/S2L2A_3.tar -C data/ImpactMesh-Flood/data
-tar -xf data/ImpactMesh-Flood/data/S1RTC.tar -C data/ImpactMesh-Flood/data
-tar -xf data/ImpactMesh-Flood/data/DEM.tar   -C data/ImpactMesh-Flood/data
-tar -xf data/ImpactMesh-Flood/data/MASK.tar  -C data/ImpactMesh-Flood/data
+rm -r data/ImpactMesh-Flood/train
+rm -r data/ImpactMesh-Flood/val
+rm -r data/ImpactMesh-Flood/test

 We use [TerraTorch](https://terrastackai.github.io/terratorch/stable/) for the model fine-tuning and provide data modules for ImpactMesh. You can download the code and configs for the fine-tuning from https://github.com/IBM/ImpactMesh.
