 ### Comlink install
+
 As you don't want to wait for a new release for this plugin when a new version of comlink is released, this plugin has comlink as a peer dependency so you can install the version of comlink that you need.
 
 ### Add it to vite.config.js
 
 ```ts
 // vite.config.js
-import { comlink } from 'vite-plugin-comlink'
+import { comlink } from "vite-plugin-comlink";
 
 export default {
-  plugins: [
-    comlink()
-  ],
+  plugins: [comlink()],
   worker: {
-    plugins: () => ([
-      comlink()
-    ])
-  }
-}
+    plugins: () => [comlink()],
+  },
+};
 ```
 
 ### Plugin order
-Put this plugin as one of the first plugins. Only other plugins that create `ComlinkWorker` or `ComlinkSharedWorker` or transform files based on the existence of  `ComlinkWorker` or `ComlinkSharedWorker` should come before this plugin!

 ### Get Worker Instance
+
 You can get to the worker instance like this:
 
 ```ts
-import { endpointSymbol } from 'vite-plugin-comlink/symbol'
+import { endpointSymbol } from "vite-plugin-comlink/symbol";
 
-const api = new ComlinkWorker<typeof import('./worker')>(new URL('./worker', import.meta.url), {/* normal Worker options*/})
+const api = new ComlinkWorker<typeof import("./worker")>(
+  new URL("./worker", import.meta.url),
+  {
+    /* normal Worker options*/
+  }
+);
 const worker = api[endpointSymbol];
 ```
 
 ## Module Worker
+
 Not all Browsers support module Workers (see https://caniuse.com/mdn-api_worker_worker_ecmascript_modules).
 
 This results in some drawbacks for fastest and best support:
 
 For fast development we use module Workers as bundling the complete worker on the fly is not performant.
 
-In default settings we bundle the whole worker at build to a single file. Therefore all browsers that support Workers, work in production.

 ## Breaking changes
+
 ### v2 to v3
-* remove of customConfigs breaking FF support in development for some projects and removing the abbility for inline worker. This is a limitation of vite so if vite adds support of it this plugin will follow
-* remove of typefile. For typescript support please write your own type file or switch to the new syntax.
-* remove of ServiceWorker support. This was considered unstable an it was hacky so it got removed. If vite adds support for building ServiceWorker this will be added!
-* you have to add comlink to `worker.plugins` array.
