 ## How do I use it?
 
-Here's an example `vite.config.ts` file. The `cssCodeSplit` option results in all CSS being emitted as a single file, which `vite-plugin-singlefile` can then inline. The `assetsInlineLimit` ensures that even very large assets are inlined in your JavaScript. The `inlineDynamicImports` also ensures that as many resources as possible are inlined. The `manualChunks` option became necessary somewhere around Vite 2.0 release to prevent the creation of a separate `vendor.js` bundle.

+- The `cssCodeSplit` option results in all CSS being emitted as a single file, which `vite-plugin-singlefile` can then inline.
+- The `assetsInlineLimit` ensures that even very large assets are inlined in your JavaScript.
+- The `inlineDynamicImports` also ensures that as many resources as possible are inlined.
+- The `manualChunks` option became necessary somewhere around Vite 2.0 release to prevent the creation of a separate `vendor.js` bundle. `outputOptions` became just `output` some time after that.
+- The `brotliSize` option just avoids the extra step of testing Brotli compression, which isn't really pertinent to a file served locally.
+- The `chunkSizeWarningLimit` option just avoids the warnings about large chunks.
+- The filename you choose for `manualChunks` ultimately doesn't matter, it will get rolled into `index.html` by the plugin.

 ### Caveats
 
 - `favicon` resources are not inlined by Vite, and this plugin doesn't do that either.
