# Choose source and scopes

> A source identifies the connected data source; scopes identify the approved data sets.

`source` identifies the connected data source, for example `icloud_notes`. `scopes` identify approved data sets, for example `["icloud_notes.notes"]`.

Start with a source that Vana Account already exposes on [`app.vana.org/sources`](https://app.vana.org/sources). For the current supported source and scope list, see the data-connectors scope registry: [`vana-com/data-connectors/SCOPES.md`](https://github.com/vana-com/data-connectors/blob/main/SCOPES.md).
