# After you import

> What happens when you import an archive or pull from GitHub — AI bootstrap in a new chat.

# After you import

You can bring an existing codebase into a Mythex project via:

* **Project settings → Export → Import into this project** (`.tar.gz`, `.tgz`, or `.zip`)
* **GitHub pull** after the repo is linked

See [GitHub, export, and import](/features/github-and-export) for what import replaces and how secrets are handled.

## AI bootstrap

After a successful import (or a pull that needs setup), Mythex can open a **new chat** and send a bootstrap prompt so the agent installs dependencies, detects how to run the app, and gets Preview healthy.

You can steer that chat like any other Build turn.

## Tips

* Prefer importing into an empty or disposable project first
* Re-add secrets in Settings after import (imported `.env` files are stripped)
* Use checkpoints before large follow-up refactors
