 ## Usage
 
-**Add threestudio link and usage here**
+By using Score Distillation Sampling (SDS) along with the Stable Zero123 model, we can produce high-quality 3D models from any input image. The process can also extend to text-to-3D generation by first generating a single image using SDXL and then using SDS on Stable Zero123 to generate the 3D object.
+
+To use Stable Zero123 for object 3D mesh generation in [threestudio](https://github.com/threestudio-project/threestudio), please follow the installation instructions and run 
+```
+python launch.py --config configs/stable_zero123.yaml --train --gpu 0 data.image_path=./load/images/dog1_rgba.png
+```
