# Run one formatter plan across a mixed-language repo and keep generated edits predictable with treefmt
Use treefmt when an agent needs one repo-level formatting plan across multiple languages instead of stitching formatter commands together ad hoc.
## Prerequisites
treefmt, the underlying language formatters you plan to invoke, a repository-level treefmt configuration file, and shell access.
## Installation
Basic usage or getting-started notes:
- What if that single command would handle all the formatters in parallel? And only format files that have changed since the previous run?
- When formatters are run in a script, they process all the files they encounter, regardless of whether or not
- You can install treefmt by downloading the binary. Find the binaries for different architectures [here](https://github.com/numtide/treefmt/releases).
