Update translations in readme.md file.

Value
As an admin I want to see the total number of members, a graph of new members.

Possible solution
Let's add this information to admins dashboard index page.

@tiagostutz as you suggested, I can make some documentation improvements for you here.

I think this would be more explicit what the idea is, as the intended use of these resources are as a "role" of user. Do you think that makes sense ?

Develop a logger that can organize the logs.
