 `gitoxide` is an implementation of `git` written in Rust for developing future-proof applications which strive for correctness and
 performance while providing a pleasant and unsurprising developer experience.
 
-There are two primary ways to use gitoxide:
-
-1. **CLI binaries**: The provided binaries `gix` and `ein` for use on the command-line allow experimentation with key features
-   like fetch and clone, and to validate the usability. 
-   `gitoxide` aspires to be a production-grade server implementation and the `ein` binary aspires to become the default way to interact
-   with git repositories.
-3. **Rust library**: Use the [gix](https://docs.rs/gix) crate in your project to access the features offered by gitoxide
-   programmatically.
+There are two primary ways to use `gitoxide`:
+
+1. **As Rust library**: Use the [`gix`](https://docs.rs/gix) crate as a Cargo dependency for API access.
+1. **As command-line tool**: The `gix` binary as development tool to help testing the API in real repositories,
+    and the `ein` binary with workflow-enhancing tools. Both binaries may forever be unstable,
+    *do not rely on them in scripts*.
