+### Skipping cache saving
+
+For some scenarios, it may be useful to only save a given subset of dependencies,
+but restore more of them for other workflows. For instance, there may be a heavy
+`extras` dependency that you do not need your entire test matrix to download, but
+you want to download and test it separately without it being saved in the cache
+archive for all runs.
+
+To achieve this, you can use `cache-save: false` on the run that uses the heavy
+dependency.
