## What it is
Fast Syntax Highlighting (F-Sy-H) is a feature-rich syntax highlighting plugin for the Zsh shell. It colorizes commands as you type, with faithful highlighting for specific commands like git, and installs via Zinit, Antigen, Zgen, Oh-My-Zsh, or manually.

## Use cases
- highlight zsh commands as i type in the terminal
- make my zsh prompt show syntax errors before running commands
- get git command highlighting in zsh
- speed up zsh syntax highlighting compared to zsh-syntax-highlighting
- colorize shell scripts interactively in zsh

## When to choose
- you use Zsh and want fast, feature-rich interactive syntax highlighting
- you want accurate highlighting for specific commands like git
- you already use Zinit, Antigen, Zgen, or Oh-My-Zsh plugin managers

## When to avoid
- you use bash or another shell instead of Zsh
- you need a minimal setup and don't want extra plugin dependencies
