Update breadcrumbs and category

Hi,
I would like to change breadcrumbs, for the moment it’s just like this :
Home / Category: [Name Category]
and when I go on sub-category it’s like this :
Home / Sub-Category: [Name Sub-Category]

I would like to see this : Home / [Name Category] / [Name Sub-Category]
How can I do ?

Moreover, articles are directly after “Home” on the Breadcrumbs : ( Home / [Name Article] )
I would like to see something like this if it’s possible : Home / [Name Category] / [Name Article]

Thanks for your help
