-## Scanning for references
-
-Before in the section on [store objects](./objects.md), we talked abstractly about scanning for references.
-Now we can make this concrete.
-
-After the derivation's command is run, Nix needs to process the "raw" output directories to turn them into legit store objects.
-There is a few steps of this, but let's start with the simple case of one input-addressed output first.
-
-\[Overview of things that need to happen.]
-
-For example, if Nix thinks `/nix/store/asdfasdfasdf-foo` and `/nix/store/qwerqwerqwer-bar` are paths the data might plausibly reference, Nix will scan all the contents of all files recursively for the "hash parts" `asdfasdfasdf`` and `qwerqwerqwer`.
