+We provide two ways to download datasets and trained models on our MEGA network disk:
+(i) Download directly from the link and put them under the corresponding project dir:
+PACS dataset is on  https://mega.nz/#F!jBllFAaI!gOXRx97YHx-zorH5wvS6uw. pacs_data and pacs_label can be put under ```<home_dir>/data/PACS/```.
+All trained models of VD and PACS are on  https://mega.nz/#F!rRkgzawL!qoGX4bT3sif88Ho1Ke8j1Q, and they can be put under `<home_dir>/model_output/`.  ＊＊The models under the ```<Feature_Critic>``` folder are the Feature_Critic trained models that can be utilized directly.＊＊
+VD dataset download should follow the instructions below.

-### Running
-First go to the Feature_Critic_VD code folder:
-```
-cd <path_to_Feature_Critic_VD_folder>
-```
-Then launch the entry script of baseline method:
