+# Examples
+
+* Download a file to the Nix store:
+
+  ```console
+  # nix store prefetch-file https://releases.nixos.org/nix/nix-2.3.10/nix-2.3.10.tar.xz
+  Downloaded 'https://releases.nixos.org/nix/nix-2.3.10/nix-2.3.10.tar.xz' to
+  '/nix/store/vbdbi42hgnc4h7pyqzp6h2yf77kw93aw-source' (hash
+  'sha256-qKheVd5D0BervxMDbt+1hnTKE2aRWC8XCAwc0SeHt6s=').
+  ```
+
+* Download a file and get the SHA-512 hash:
+
+  ```console
+  # nix store prefetch-file --json --hash-type sha512 \
+      https://releases.nixos.org/nix/nix-2.3.10/nix-2.3.10.tar.xz \
+    | jq -r .hash
+  sha512-6XJxfym0TNH9knxeH4ZOvns6wElFy3uahunl2hJgovACCMEMXSy42s69zWVyGJALXTI+86tpDJGlIcAySEKBbA==
+  ```
+
+# Description
+
+This command downloads the file *url* to the Nix store. It prints out
+the resulting store path and the cryptographic hash of the contents of
+the file.
+
+The name component of the store path defaults to the last component of
+*url*, but this can be overriden using `--name`.
