 ### `dest`
 
-**Optional** Where to store PNPM files.
-
-### `bin_dest`
-
-**Optional** Where to store executables (`pnpm` and `pnpx` commands).
-
-### `registry`

+### `cache`

+**Optional** (_type:_ `boolean`, _default:_ `false`) Whether to cache the pnpm store directory.
+
+### `cache_dependency_path`
+
+**Optional** (_type:_ `string|string[]`, _default:_ `pnpm-lock.yaml`) File path to the pnpm lockfile, which contents hash will be used as a cache key.
