+### Read-only access
+
+Some workflow runs only have read-only access to the cache. A common case is a workflow triggered by a pull request from a fork: such runs can **restore** existing caches but may not be permitted to **save** new ones.
+
+When the cache token is read-only, the save step does not fail the job. Instead, `@actions/cache` reports the denial once as a warning (for example, `Failed to save: ... cache write denied: ...`) and the step completes successfully without writing a cache entry. Restores in the same run continue to work as usual.
+
+> **Note** This applies to the action's normal save path as well as the standalone [Save action](./save/README.md). If you intentionally want a restore-only setup, see [Make cache read only / Reuse cache from centralized job](./caching-strategies.md#make-cache-read-only--reuse-cache-from-centralized-job).
