⚠️ Potential issue

Restore .zsh extension in the example source line.

The upstream zsh-syntax-highlighting plugin ships zsh-syntax-highlighting.zsh, and this is the file users are instructed to source in their .zshrc. Switching the example to .sh points to a non-existent path and will break the activation instructions. Please keep the .zsh suffix here.

-      source /some/path/to/your/zsh-syntax-highlighting/zsh-syntax-highlighting.sh
+      source /some/path/to/your/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh

📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Suggested change

	source /some/path/to/your/zsh-syntax-highlighting/zsh-syntax-highlighting.sh
	source /some/path/to/your/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh

🤖 Prompt for AI Agents

In INSTALL.md around line 23, the example source path uses the incorrect .sh
extension which points to a non-existent file; change the filename in the
example back to zsh-syntax-highlighting.zsh so the source line matches the
upstream plugin and will correctly activate when added to users' .zshrc.
