+# Updating the parser
+
+YouTube is constantly changing, so it is not rare to see YouTube crawlers/scrapers breaking every now and then. 
+
+Our parser, on the other hand, was written so that it behaves similarly to an official client, parsing and mapping renderers (a.k.a YTNodes) dynamically without hard-coding their path in the response.  This way, whenever a new renderer pops up (e.g; YouTube adds a new feature / minor UI changes) the library will print a warning like this in the console:
+```
+InnertubeError: SomeRenderer not found!
+This is a bug, want to help us fix it? Follow the instructions at https://github.com/LuanRT/YouTube.js/blob/main/docs/updating-the-parser.md or report it at https://github.com/LuanRT/YouTube.js/issues!
+    at Parser.printError (...)
+    at Parser.parseItem (...)
+    at Parser.parseArray (...) {
+  info: {
+    // renderer data, can be used as a reference to implement the renderer parser
+  },
+  date: 2022-05-22T22:16:06.831Z,
+  version: '2.2.3'
+}
+```
+
+This warning, however, **does not** throw an error. The parser itself will continue working normally, even if a parsing error occurs in an existing renderer parser.
+
+## Adding a new renderer parser
+
+Thanks to the modularity of the parser, a renderer can be implemented by simply adding a new file anywhere in the [classes directory](../src/parser/classes)!
+
+For example, say we found a new renderer named `verticalListRenderer`, to let the parser know it exists we would have to create a file with the following structure:
+
+> `../classes/VerticalList.ts`
+```ts
+import Parser from '..';
+import { YTNode } from '../helpers';
+
+class VerticalList extends YTNode {
+  static type = 'VerticalList';

 To use YouTube.js in the browser you must proxy requests through your own server. You can see our simple reference implementation in Deno in `examples/browser/proxy/deno.ts`.

-Once the proxy is set up you need to tell Innertube about it when instantiating it.
+We'll use our own fetch implementation to proxy requests through our server. This is a simple example, but you can use any fetch implementation you want.

 ```ts
 import { Innertube } from "youtubei.js/build/browser";

 const yt = await Innertube.create({
-    browser_proxy: {
-        host: "localhost",
-        schema: 'http',
-    }
-})
+    fetch: async (input, init) => {
+        // url
+        const url = typeof input === 'string'
+            ? new URL(input)
+            : input instanceof URL
+            ? input
+            : new URL(input.url);
+
+        // transform the url for use with our proxy
+        url.searchParams.set('__host', url.host);
+        url.host = 'localhost:8080';
+        url.protocol = 'http';
+
+        const headers = init?.headers
+            ? new Headers(init.headers)
+            : input instanceof Request
+            ? input.headers
+            : new Headers();
+
+        // now serialize the headers
+        url.searchParams.set('__headers', JSON.stringify([...headers]));
+
+        // copy over the request
+        const request = new Request(
+            url,
+            input instanceof Request ? input : undefined,
+        );
+
+        headers.delete('user-agent');
+
+        // fetch the url
+        return fetch(request, init ? {
+            ...init,
+            headers
+        } : {
+            headers
+        });
+    },
+    cache: new UniversalCache(),
+});
 ```

 after that you can use the library as normal.

-Here we're taking a similar approach, the parser goes through all the renderers and parses their inner element(s). The final result is a nicely structured JSON, and on top of that it also parses navigation endpoints which allows us to make an API call with all required parameters in one line and even emulate client actions (eg; clicking a button).
