+### FLUX.1 ControlNet training
+We have added a new training script for ControlNet training. The script is flux_train_control_net.py. See --help for options.
+
+Sample command is below. It will work with 80GB VRAM GPUs.

 ### FLUX.1 OFT training
 
 You can train OFT with almost the same options as LoRA, such as `--timestamp_sampling`. The following points are different.
