-`Vcs` is an interface composed of [Traits](./traits.md), each providing different functionalities associated with Git interaction. The dynamic dispatch implementation of Vcs is powered by the [provider](https://github.com/mbarbin/provider) library.

 # The Power of Traits in `Vcs`
 
-The `Vcs` library leverages the `provider`-based parametric model to offer a
-flexible and adaptable interface for Git interaction. This model, also used in
-the `Eio` library (`Eio.Resource`), allows us to define small scopes of
-functionality, or `Traits`, within the `Vcs` library.

 ## Experience with `providers`
 
-Our use of the [provider](https://github.com/mbarbin/provider) based parametric
-library in `Vcs` serves as a practical, real-world case study of this pattern.

-We aim to bring this pattern to the attention of the community, fostering a
-general understanding that can be applied to other projects using the same

 ## Granularity of the Interface via Trait Granularity
 
-The `Trait` design of `provider` allows us to define specific and isolated
-sub-functionalities within the `Vcs` library. This granularity enables different
-providers to choose which `Trait` they wish to implement, offering a level of
-flexibility not possible with a monolithic functor.

-With `Traits`, you can select a provider with the specific set of traits you
-need, without changing any other code. As explained
-[here](https://mbarbin.github.io/provider/provider/Provider/Interface/index.html#type-t),
-provider interfaces come with some notion of phantom types, offering additional
-compiler assistance.
