Lack of documentation on templates usage with CLI tool.

[Templates explanation](http://joel-costigliola.github.io/assertj/assertj-assertions-generator.html#generated-assertions-templates)
[CLI usage guide](http://joel-costigliola.github.io/assertj/assertj-assertions-generator.html#quickstart)
`You can change what is generated by modifying the templates used for assertions creation (have a look at templates directory)`

It's not clear at all what should I be looking at there. I see templates, but documentation gives no idea on how to change the type of assertions I want to generate. Documentation explains which template does what, and also what all these variables within templates stand for. But how do I "feed" a needed template to a CLI?
E.g., by default, classes with custom *straight* assertions are generated. How do I get *soft* assertions instead? Or some of these templates is (are?) used by CLI by default, and I need to modify it?

Lisez l’explication liée sur les Templates et le guide d’utilisation de la CLI, puis examinez le répertoire templates référencé par la documentation. Déterminez comment la CLI sélectionne ou accepte les templates et comment les utilisateurs demanderaient des alternatives telles que soft assertions. Le travail est considéré comme terminé lorsque la documentation fournit un workflow concret et reproductible de sélection des templates.
