 ### Other caching options
 
-There are two additional options related to caching.  You can specify where in your system that this plugin caches with the `cacheLocation` option.  By default it will figure out automatically where based on your username and your OS to store the cache via the [appdirectory](https://www.npmjs.com/package/appdirectory) module.  Additionally, you can specify how many max static caches to store with `staticCacheMaxVersions`, as a simple attempt to limit disk space usage for caching.  This is DISABLED (set to 0) by default.
