     - `module` corresponds to the module for which you want to give a parameter (`prepare`, `annotate`, `pangenome`, `corepers`, `align`, `tree`).
     - a boolean parameter is set with one of the boolean values (case-insensitive): 'yes'/'no', 'on'/'off', 'true'/'false' or '1'/'0' (examples with `param3`, `param4` and `param5` which are all booleans with True value)
