 The training and evaluation scripts expect the dataset to live at `data/minecraft` by default.
 
+## Checkpoints
+
+Pretrained checkpoints are hosted on Hugging Face: `zeqixiao/worldmem_checkpoints`.
+
+Example download to `checkpoints/`:
+
+```bash
+huggingface-cli download zeqixiao/worldmem_checkpoints diffusion_only.ckpt --local-dir checkpoints
+huggingface-cli download zeqixiao/worldmem_checkpoints vae_only.ckpt --local-dir checkpoints
+huggingface-cli download zeqixiao/worldmem_checkpoints pose_prediction_model_only.ckpt --local-dir checkpoints
+```
+
+Then point your scripts or configs to these files, for example:
+
+```bash
+python -m main +name=train +diffusion_model_path=checkpoints/diffusion_only.ckpt +vae_path=checkpoints/vae_only.ckpt
+```
