 This blog post accompanies an [upcoming major change to the `rust-lang/rust` build system][stage0-redesign-pr] (see also [Major Change Proposal 619][redesign-stage0-mcp]). This will have no impact on the distributed artifacts from [rust-lang/rust], but the way we build those artifacts is changing.
 
-This blog post focuses on motivation for the change and attempts to build a mental model for how the system works, rather than deep diving on workflow changes. See the [rustc-dev-guide](https://rustc-dev-guide.rust-lang.org/building/bootstrapping/what-bootstrapping-does.html) for details on how you might need to change your workflow with these changes.
