I think it's better to split this part into a new "Manual Installation" section, something like this. wdyt? I can help updating all the deployment docs.

qwik/packages/docs/src/routes/docs/deployments/static/index.mdx

Lines 21 to 28 in c1ad095

	Above command will create a directory at project root named `adapters/static/vite.config.ts` with the below code.
	```tsx file="adapters/static/vite.config.ts"
	import { staticAdapter } from "@builder.io/qwik-city/adapters/static/vite";
	import { extendConfig } from '@builder.io/qwik-city/vite';
	import baseConfig from '../../vite.config';

If it's not recommended to do manual installation, then it's better to remove the code from the docs, something like https://qwik.dev/docs/deployments/firebase/
