The main choice that you have is which files to place on the volume. For example, Node.js uses the folder`node_modules` for its dependencies which are placed under the project folder[which is automatically placed under the volume]({{site.baseurl}}/docs/pipelines/introduction-to-codefresh-pipelines/#cloning-the-source-code). So all contents of`node_modules` will be cached by default without any further action on your part.

If you are using [Codefresh on-premises]({{site.baseurl}}/docs/installation/codefresh-on-prem/), this kind of caching is not available for the built-in runtime.<br>You need to use the[Codefresh Runner]({{site.baseurl}}/docs/installation/codefresh-runner/) with your own runtime to activate volume caching.
