# Track items you already installed

Adopt Ballmac items you installed with plain shadcn, so ballmac update can merge new versions into them.

Installed with plain `shadcn add`? Adopt the items:

```bash
npx @ballmac/cli track
npx @ballmac/cli track dialog button
```

The first command tracks every Ballmac item found in the project. The second tracks only the items you name.

## How it records your files

A file identical to what shadcn writes today is recorded as untouched. One that differs is recorded **without a base**, because it may be edited or from an older version and there is no way to tell.

For those files, an update puts the new version beside your file as `<file>.ballmac-new` instead of guessing.

## Declare a file current

Once you have compared the two files, tell `ballmac` your file is current:

```bash
npx @ballmac/cli track --rebase button
```

From then on, `ballmac update` merges new versions into it. See [Update components without losing your edits](https://ui.ballmac.com/docs/guides/update-components).
