-To persist the cache between workflow runs, use the `actions/cache` action to save and restore the cache file located at `~/.crowdin/cache.json`:
+The CLI writes the cache to the `.crowdin` directory in the current working directory. To persist the cache between workflow runs, restore and save this directory using `actions/cache/restore` and `actions/cache/save`.

-The cache key includes the current branch name and the `crowdin.yml` file hash, so each branch maintains its own cache and the cache will be invalidated when your Crowdin configuration changes. The `restore-keys` ensures that even if the exact key doesn't match (e.g., when `crowdin.yml` changes), a previous cache for the same branch will be restored, which is useful for incremental updates.

-Make sure to pass the `--cache` argument to the `upload_sources_args` option to use the cache.
+The restore step first tries an exact match on `crowdin-${{ github.ref_name }}` and falls back to the `restore-keys` prefix to pick up the latest run's cache. The save step always runs (even if the upload fails) and writes a new cache entry keyed with the run ID. Make sure to pass `--cache` in `upload_sources_args` so the CLI uses the cache.
