## What it is
PSReadLine is a PowerShell module that replaces the built-in command line editing experience with a bash-inspired readline implementation. It adds syntax coloring, multi-line editing, customizable key bindings, history search, and completion to PowerShell consoles.

## Use cases
- add syntax highlighting to the PowerShell console
- search shell history with Ctrl-R like in bash
- customize key bindings in PowerShell
- get better multi-line command editing in PowerShell
- share command history across PowerShell sessions
- get bash-style tab completion in PowerShell

## When to choose
- you use PowerShell interactively and want a modern readline experience
- you want syntax coloring and error notification while typing commands
- you need emacs or bash-style editing modes in PowerShell

## When to avoid
- you only run PowerShell scripts non-interactively
- you use a shell other than PowerShell
- you need a fully POSIX readline-compatible implementation

## Facets
