 ## Building
 
 You can look at the [build instructions](docs/building.md) for more details.
+
+### macOS with Nix or direnv (preferred)
+
+Use one shared toolchain path for both `nix develop` and `direnv`.
+
+1. Enable direnv for this repo (optional convenience):
+   - `.envrc` uses `use flake`
+   - run `direnv allow`
+2. Enter the flake environment (if not using direnv):
+   - `nix develop`
+3. Run build:
+   - `make build-macos`
+
+### macOS without Nix (Homebrew host setup)
+
+Use this only when you are not building through Nix/flake.
+
+1. Install host tools:
+   - `make bootstrap-macos`
+2. Run build:
+   - `make build-macos`

 Here you will find instructions on how to install the necessary tools for building and running the app.
 
+## Nix / direnv (recommended for macOS and Linux)
+
+A `flake.nix` and `.envrc` provide a reproducible development environment on macOS (Determinate Nix on macOS Tahoe ARM tested), NixOS, and other Linux distributions.
+
+```
+# enter the dev shell
+nix develop          # or: direnv allow
+
+# build
+make build-macos     # on macOS
+make build-linux     # on Linux
+```
+
+The Makefile is the single entry point for all builds. Two Rust toolchains are provisioned by the flake: `stable` (default, used for frostdart / coinlib / secp256k1 / etc.) and `1.85.1` (pinned for `flutter_libepiccash` and `flutter_libmwc`). The bootstrap scripts `scripts/install_macos_build_tools.sh` and `scripts/install_nixos_build_tools.sh` install equivalent host toolchains for non-Nix setups.
+
+The legacy per-platform instructions below remain valid for developers who do not want to use Nix.
+
 ## Prerequisites
 
 - The only OS supported for building Android and Linux desktop is Ubuntu 24.04.  Windows builds require using Ubuntu 24.04 on WSL2.  macOS builds for itself and iOS.  Advanced users may also be able to build on other Debian-based distributions like Linux Mint.

 ### Rust
 Install [Rust](https://www.rust-lang.org/tools/install) on the Windows host (not in WSL2).  Download the installer from [rustup.rs](https://rustup.rs), make sure it works on the commandline (you may need to open a new terminal), and install the following versions:
 ```
-rustup install 1.89.0 1.85.1
-rustup default 1.89.0
+rustup toolchain install stable 1.85.1
+rustup default stable
 cargo install cargo-ndk
 ```
+Note: the frostdart Windows build scripts additionally require Rust `1.71.0-x86_64-pc-windows-msvc` (and the `gnu` variant for cross-compiles). Install with `rustup toolchain install 1.71.0-x86_64-pc-windows-msvc` if you build on or for Windows.
 
 ### Windows SDK and Developer Mode
 Install the Windows SDK: https://developer.microsoft.com/en-us/windows/downloads/windows-sdk/  You may need to install the [Windows 10 SDK](https://developer.microsoft.com/en-us/windows/downloads/sdk-archive/), which can be installed [by Visual Studio](https://stackoverflow.com/a/73923899) (`Tools > Get Tools and Features... > Modify > Individual Components > Windows 10 SDK`).

Subject: [PATCH 111/118] fix: add Rust toolchain to test-mwc target and port
 build.yaml macos job to Makefile

make build-macos now drives the full macOS release build via the Makefile,
replacing the old build_app.sh -d -s download path with source compilation.

build.yaml: remove redundant Configure/GetDeps/GitVersions/Build steps now
handled by make build-macos. Add dtolnay/rust-toolchain@stable + 1.85.1 install
so check-reqs passes.

Makefile: test-mwc now ensures local stable rustup toolchain is installed and
defaulted before flutter test -d macos, fixing missing flutter_libsparkmobile
framework linker error when Cargokit rebuilds for Debug mode.
