+### Disable async git prompt
+
+Async prompt functions are an experimental feature (included on April 3, 2024) that allows Oh My Zsh to render prompt information
+asyncronously. This can improve prompt rendering performance, but it might not work well with some setups. We hope that's not an
+issue, but if you're seeing problems with this new feature, you can turn it of by setting the following in your .zshrc file,
+before Oh My Zsh is sourced:
+
+```sh
+zstyle ':omz:alpha:lib:git' async-prompt no
+```
+
 #### Notice <!-- omit in toc -->
 
 > This feature is currently in a testing phase and it may be subject to change in the future.
