-cmsis-pack-manager is a python module, Rust crate and command line utility for managing current device information that is stored in many CMSIS PACKs. Users of cmsis-pack-manager may query for information such as processor type, flash algorithm and memory layout information in a python program or through the command line utility, `pack-manager`, provided as part of this module.

 # Building
 
-To build cmsis-pack-manager locally, Install a stable rust compiler.
-See https://rustup.rs/ for details on installing `rustup`, the rust
-toolchain updater. Afterwards, run `rustup update stable` to get the
-most recent stable rust toolchain and build system.

+updater. Afterwards, run `rustup toolchain install` to get the Rust toolchain
+and build system for building `cmsis-pack-manager`.
 
-After installing the rust toolchain and downloading a stable compiler,
-run `python2 setup.py bdist_wheel` from the root of this repo to
-generate a binary wheel (`.whl` file) in the same way as we release.
+After installing the rust toolchain and downloading a stable compiler, run
+`pip wheel .` from the root of this repo to generate a binary wheel (`.whl`
+file). Alternatively you can run `pip install maturin cffi` and then
+`maturin build` for a process closer to the way we build releases.
 
 For testing purposes, there is a CLI written in Rust within the rust
 workspace as the package `cmsis-cli`. For example From the `rust`
