+### Updates
+- [05/07/2023] We plan to release an re-implementation of training code through [lab4d](https://github.com/lab4d-org/lab4d).
+- [01/22/2023] This repo is under development. It will contain the pre-trained category models of cats, dogs, and human.

+cd rac
+
+# base dependencies
+conda env create -f misc/rac-cu113.yml
+
+# other dependencies

-## Pretrained models
+### Pretrained models
 ```
-# download optimized model
+# download model weights
 wget https://www.dropbox.com/sh/h1w82lb4rg48jui/AACD8q-DCFjyDhRx0-j7EjWLa -O tmp.zip
 mkdir -p logdir
 unzip tmp.zip -d ./logdir
 rm tmp.zip
 ```
+
+### Re-targeting
+```
+python explore.py --flagfile logdir/dog80-v0/opts.log --nolineload --seqname dog80 --full_mesh --noce_color --svid 69 --tvid 45
+```
+retargets the source video 69 to target video 45. Results are saved at `logdir/dog80-v0/explore-motion-69.mp4`.
