+### Layout conditioned LiDAR generation with MaskGIT pipeline
+
+1. Download LiDAR VQVAE and LiDAR MaskGIT generation model checkpoint.
+2. Prepare the dataset ( [nuscenes_scene-0627_lidar_package.zip](http://103.237.29.236:10030/nuscenes_scene-0627_lidar_package.zip) ).
+3. Modify the values of `json_file`, `vq_point_cloud_ckpt_path`, `vq_blank_code_path` and `model_ckpt_path` to the paths of your dataset and checkpoints in the json file `examples/lidar_maskgit_preview.json` .
+4. Run the following command to visualize the LiDAR of the validation set and save the generated point cloud as `.bin` file.
+
+```bash
+PYTHONPATH=src python src/dwm/preview.py -c examples/lidar_maskgit_preview.json -o output/test
+```
