 === Prerequisites
 
 * Rust 1.74 or later,
-* `lld` for faster linking,
-** You can use other linkers instead, just update the `.cargo/config.toml` file.
 * Linux kernel >= 4.5,
 ** Required for Seccomp BPF support.
 * For gRPC support (under `grpc` feature):
-** `protoc` as Protocol Buffers compiler,
-** `buf` for gRPC dependencies management.
+** https://github.com/protocolbuffers/protobuf?tab=readme-ov-file#protobuf-compiler-installation[`protoc`] >= 3.15,
+** https://github.com/bufbuild/buf/[`buf`] for gRPC dependencies management.
 * For `.deb` package generation, a Debian/Ubuntu system with `dpkg-dev` and `liblzma-dev` installed.
