+**Configuration files.**
+Options can be set through a `should.cfg` file.
+For example, a `should.cfg`.with the following lines is equivalent to giving `--xml --mod r` options to every `should` call:
+```
+--xml
+
+--mod
+r
+```
+
+Other configuration files can be provided when calling should with `@my.cfg`, see [demo/variables.should](demo/variables.should).
+
 **Output.**
 By default, `should` only writes to the standard output.
 The `--log`, `--tap` and `--xml` options enable to store the actual output of the tested commands
