+# Examples
+
+* Verify the entire Nix store:
+
+  ```console
+  # nix store verify --all
+  ```
+
+* Check whether each path in the closure of Firefox has at least 2
+  signatures:
+
+  ```console
+  # nix store verify -r -n2 --no-contents $(type -p firefox)
+  ```
+
+* Verify a store path in the binary cache `https://cache.nixos.org/`:
+
+  ```console
+  # nix store verify --store https://cache.nixos.org/ \
+      /nix/store/v5sv61sszx301i0x6xysaqzla09nksnd-hello-2.10
+  ```
+
+# Description
+
+This command verifies the integrity of the store paths *installables*,
+or, if `--all` is given, the entire Nix store. For each path, it
+checks that
+
+* its contents match the NAR hash recorded in the Nix database; and
+
+* it is *trusted*, that is, it is signed by at least one trusted
+  signing key, is content-addressed, or is built locally ("ultimately
+  trusted").
+
+# Exit status
+
+The exit status of this command is the sum of the following values:
+
+* **1** if any path is corrupted (i.e. its contents don't match the
+  recorded NAR hash).
+
+* **2** if any path is untrusted.
+
+* **4** if any path couldn't be verified for any other reason (such as
+  an I/O error).
