 A thin wrapper around [git-filter-repo](https://github.com/newren/git-filter-repo) for syncing filtered commits from a private repository to a public repository.
 
+## Overview
+
+git-sync-filtered clones a private repository, filters it to only include specified paths using git-filter-repo, and pushes the result to a public repository's sync branch. This enables maintaining a public subset of a private repository while preserving commit history.
