 By default all depot directories called out below are cached.
 
+### Requirements
+
+This action uses [`jq`](https://github.com/jqlang/jq) to parse JSON.
+`jq` is installed by default in GitHub-hosted runners.
+[`dcarbone/install-jq-action`](https://github.com/dcarbone/install-jq-action) is used to check that `jq` is available and install it if not.
+**Note:** installing `jq` with `dcarbone/install-jq-action` requires that curl is available; this may not be the case in custom containers.
+
 ### Optional Inputs
 
 - `cache-name` - The cache key prefix. Defaults to `julia-cache;workflow=${{ github.workflow }};job=${{ github.job }}`. The key body automatically includes the OS and, unless disabled with `include-matrix`, the matrix vars. Include any other parameters/details in this prefix to ensure one unique cache key per concurrent job type.
@@ -40,6 +47,7 @@ By default all depot directories called out below are cached.
 - `cache-compiled` - Whether to cache the depot's `compiled` directory. Defaults to `true`.
 - `cache-scratchspaces` - Whether to cache the depot's `scratchspaces` directory. Defaults to `true`.
 - `cache-logs` - Whether to cache the depot's `logs` directory. Defaults to `true`. Helps auto-`Pkg.gc()` keep the cache small.
+- `save-always` - Whether to save the cache even when the job fails. Defaults to `true`. This is useful as the Julia depot should mostly be reusable from a failing job.
 - `delete-old-caches` - Whether to delete old caches for the given key. Defaults to `true`.
 - `token` - A [GitHub PAT](https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/managing-your-personal-access-tokens). Defaults to `github.token`. Requires `repo` scope to enable the deletion of old caches.
