+Notes:
+- [`CARGO_RESOLVER_INCOMPATIBLE_RUST_VERSIONS`](../reference/config.md#resolverincompatible-rust-versions) is set to ensure the [resolver](../reference/resolver.md) doesn't limit selected dependencies because of your project's [Rust version](../reference/rust-version.md).
+
 For projects with higher risks of per-platform or per-Rust version failures,
 more combinations may want to be tested.
