 ### Example
 
-`fawkes -d ./imgs --mode mid`
+`fawkes -d ./imgs --mode low`
 
 ### Tips
 - The perturbation generation takes ~60 seconds per image on a CPU machine, and it would be much faster on a GPU machine. Use `batch-size=1` on CPU and `batch-size>1` on GPUs. 
-- Turn on separate target if the images in the directory belong to different person, otherwise, turn it off. 
-- Run on GPU. The current fawkes package and binary does not support GPU. To use GPU, you need to clone this, install the required packages in `setup.py`, and replace tensorflow with tensorflow-gpu. Then you can run fawkes by `python3 fawkes/protection.py [args]`.

 ### How do I know my images are secure? 
-We are actively working on this. Python script that can test the protection effectiveness will be ready shortly.
