-      This contains the status of this nightly. Core is built with
-      <code>cargo build --release -Zbuild-std=core</code>. This checks that
-      codegen/linking of core works, but does not check whether std builds.
-    </p>
-    <p>
-      std is being built with <code>cargo check -Zbuild-std</code>. If a target
-      does not support std, the std column represents core/alloc. This checks
-      that std checks (on targets that have it) but does not check whether
-      codegen/linking works.
+      The build is performned with <code>cargo build --release -Zbuild-std</code> for a library crate.
 
-      For older builds, <code>cargo miri setup</code> was used instead.

-      ⚠️ The core build is broken in general for this nightly, so no data is available ⚠️
+      This checks whether everything builds successfully (excluding binary linking, which often requires complex toolchains).
+      For no-std targets, Cargo's build-std logic is used for figuring out whether to build std or not.
+      On older targets (older than November 2024) this does not always work reliably, so some failed std builds there are simply no-std targets.
