 ## Compatibility With Other ZLE Plugins
 
-### [`zsh-syntax-highlighting`](https://github.com/zsh-users/zsh-syntax-highlighting)
-
-Source `zsh-autosuggestions.zsh` *before* `zsh-syntax-highlighting`.
-
-Call `autosuggest_start` *after* sourcing `zsh-syntax-highlighting`.
-
-For example:
-
-```sh
-source ~/.zsh/zsh-autosuggestions/dist/autosuggestions.zsh
-source ~/.zsh/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh
-
-autosuggest_start
-```
-

 ### [`zsh-history-substring-search`](https://github.com/zsh-users/zsh-history-substring-search)
 
 When the buffer is empty and one of the `history-substring-search-up/down` widgets is invoked, it will call the `up/down-line-or-history` widget. If the `up/down-line-or-history` widgets are in `ZSH_AUTOSUGGEST_CLEAR_WIDGETS` (the list of widgets that clear the suggestion), this can create an infinite recursion, crashing the shell session.
