 # Additional arguments are:
 #   - `postgresql` postgresql package of the version of postgresql this extension should be build for.
 #                  Needs to be the build platform variant.
-#   - `useFakeRustfmt` Wether to use a noop fake command as rustfmt. cargo-pgx tries to call rustfmt.
+#   - `useFakeRustfmt` Whether to use a noop fake command as rustfmt. cargo-pgx tries to call rustfmt.
 #                      If the generated rust bindings aren't needed to use the extension, its a
 #                      unnecessary and heavy dependency. If you set this to true, you also
 #                      have to add `rustfmt` to `nativeBuildInputs`.
