 Adding this information helps users who have needs related to build transparency and supply-chain security to gain some visibility into their installed software or set policy to allow or disallow installation based on source provenance.
 
-The presence of a particular `sourceType` in a package's `meta.sourceProvenance` list indicates that the package contains some components falling into that category, though the *absence* of that `sourceType` does not *guarantee* the absence of that category of `sourceType` in the package's contents. A package with no `meta.sourceProvenance` set implies it has no *known* `sourceType`s other than `fromSource`.

A package with no `meta.sourceProvenance` set implies it has no *known* components with any of the `sourceTypes` below.
 
 The meaning of the `meta.sourceProvenance` attribute does not depend on the value of the `meta.license` attribute.
 
-### `lib.sourceTypes.fromSource` {#lib.sourceTypes.fromSource}
