+### Feature Discovery
+
+> Can `gix` do what I need it to do?
+
+The above can be hard to answer and this paragraph is here to help with feature discovery.
+
+Look at [`crate-status.md`](https://github.com/Byron/gitoxide/blob/main/crate-status.md) for a rather exhaustive document that contains
+both implemented and planned features.
+
+Further, the [`gix` crate documentation with the `git2` search term](https://docs.rs/gix/0.54.1/gix/?search=git2) helps to find all currently
+known `git2` equivalent method calls. Please note that this list is definitely not exhaustive yet, but might help if you are coming from `git2`.
