# Caching Dependencies

Caching dependencies in GitHub Actions stores files like package manager directories between workflow runs, avoiding the need to reinstall them from scratch every time. The `actions/cache` action saves and restores these files based on a key, often derived from a lockfile's hash. This significantly speeds up workflows that install the same dependencies repeatedly across multiple runs.
