 To download the datasets, follow these steps:
 - Fill out the license agreement in this [form](https://docs.google.com/forms/d/e/1FAIpQLScPwhlUcHu_mwBqq5kQzT2VRIRwg_rJvF0IWYBk_LxEZiJIFg/viewform)
 - After submitting the form, you will receive a key (igibson.key). Copy it into the folder that will contain the dataset, as default: `your_installation_path/igibson/data`
-- Download the datasets from [here](https://storage.googleapis.com/gibson_scenes/ig_dataset.zip) (size ~20GB).
-- Unzip the zip file into the desired folder: `unzip ig_dataset.zip -d your_installation_path/igibson/data`
+- Download the datasets from [here](https://storage.googleapis.com/gibson_scenes/ig_dataset.tar.gz) (size ~20GB).
+- Unzip the zip file into the desired folder
 - (Optional) You may need to update the config file (`your_installation_path/igibson/global_config.yaml`) to reflect the location of the `ig_dataset` by changing the entry `ig_dataset_path` if you unzip the zip file.
 
 After this process, you will be able to sample and use the scenes and objects in iGibson, for example, to evaluate your embodied AI solutions in the [BEHAVIOR benchmark](https://behavior.stanford.edu/).

 Third, we need to download datasets of scenes (Gibson or iGibson), and, possibly, the BEHAVIOR Datasets of Object Models. 
-For interactive tasks, you need to download iGibson 2.0 Scenes and the BEHAVIOR Dataset of Objects, or iGibson 1.0 Scenes. They include several fully interactive scenes and hundreds of 3D objects to use with our simulator.

 For navigation tasks, you could use the interactive scenes, but we also provide back-compatibility to the Gibson Dataset, Stanford 2D-3D-Semantics Dataset, and Matterport3D Dataset that include non-interactive scene models.
 Follow the detailed instructions [here](dataset.md) to download the aforementioned datasets.
