 Loosely, you'll need the following:
 
 - **To build Vector:** Have working Rustup, Protobuf tools, C++/C build tools (LLVM, GCC, or MSVC), Python, and Perl, `make` (the GNU one preferably), `bash`, `cmake`, `GNU coreutils`, and `autotools`.
+- **To run `make test`:** Install [`cargo-nextest`](https://nexte.st/)
 - **To run integration tests:** Have `docker` available, or a real live version of that service. (Use `AUTOSPAWN=false`)
 - **To run `make check-component-features`:** Have `remarshal` installed.
 - **To run `make check-licenses` or `cargo vdev build licenses`:** Have `rust-license-tool` [installed](https://github.com/DataDog/rust-license-tool).
