+ * This method creates a list of URLs to precache, referred to as a "precache
+ * manifest", based on the options you provide.
+ *
+ * It also takes in additional options that configures the service worker's
+ * behavior, like any `runtimeCaching` rules it should use.
+ *
+ * Based on the precache manifest and the additional configuration, it writes
+ * a ready-to-use service worker file to disk at `swDest`.
+ *
+ * @param {Object} config Please refer to the
+ * [configuration guide](https://developers.google.com/web/tools/workbox/modules/workbox-build#full_generatesw_config).
+ * @return {Promise<{count: number, size: number, warnings: Array<string>}>}
+ * A promise that resolves once the service worker file has been written to
+ * `swDest`. The `size` property contains the aggregate size of all the
+ * precached entries, in bytes, and the `count` property contains the total
+ * number of precached entries. Any non-fatal warning messages will be returned
+ * via `warnings`.
