 ### Homebrew
 
 For Mac, you can use Homebrew.
 
 ```sh
 brew install libtorch
 ```
 
 Then install the gem (no need for `bundle config`).
 
+## Performance

 ## rbenv
 
 This library uses [Rice](https://github.com/jasonroelofs/rice) to interface with LibTorch. Rice and earlier versions of rbenv don’t play nicely together. If you encounter an error during installation, upgrade ruby-build and reinstall your Ruby version.
