+# Toolchain Bundle (`toolchain-bundle/`)
+
+To ensure that tools like `make`, `nasm`, `qemu`, or `perl` are available in the Bazel build environment, we provide a `toolchain-bundle`. This bundle is pre-built and fetched as an external repository, allowing Bazel to use these tools without needing to install them on the host system. They are built for both `x86_64-unknown-linux-musl` and `aarch64-unknown-linux-musl` platforms with Nix.
+
+You can build these toolchains by invoking the `nix-build` via `nix-build build/toolchain/toolchain-bundle/default.nix`

+# Rust EFI Toolchain (`rust-efi/`)
