# Importing app

If you have an existing app that you want to bring into Dyad

Importing apps is **experimental** as of [v0.6.0](/content/docs/releases/0.6.0). Please [report bugs](/content/docs/help#report-a-bug/index.html).

If you’ve built your app using tools like Lovable, V0, Bolt, or anything else, you can now bring it into Dyad.

## [AI Rules](/content/docs/guides/importing#ai-rules/index.html)

Dyad relies on a file called `AI_RULES.md` in the root of your project. This file contains AI rules — instructions that guide Dyad as it edits your app. It should describe your app’s tech stack and architecture so Dyad can make informed, meaningful changes.

If your project doesn’t already have an `AI_RULES.md` file, Dyad will automatically generate one when you import the app.

## [Limitations](/content/docs/guides/importing#limitations/index.html)

Since app importing is still experimental, there are a few important limitations to keep in mind:

### [JavaScript apps only](/content/docs/guides/importing#javascript-apps-only/index.html)

Dyad currently only supports Node.js-based JavaScript apps. You can’t import apps built with non-JavaScript frameworks like Laravel (PHP) or Ruby on Rails.

### [`npm run dev` required](/content/docs/guides/importing#npm-run-dev-required/index.html)

Dyad runs `npm run dev` by default to start the local development server. If your app doesn't include a `dev` script, you’ll need to add one in `package.json`.

Most modern JavaScript frameworks (e.g. Vite, Next.js) already follow this convention, so it shouldn’t be an issue in most cases.
