+  - `substitutions`: The list of substitution arguments to pass
+    See https://nixos.org/manual/nixpkgs/stable/#fun-substitute
+  - `replacements`: Deprecated version of `substitutions`
+    that doesn't support spaces in arguments.
+
+  Example:
+
+  ```nix
+  { substitute }:
+  substitute {
+    src = ./greeting.txt;
+    substitutions = [
+      "--replace"
+      "world"
