 ## Building the target
 
-The targets can be built by enabling them for a `rustc` build in
-`config.toml`, by adding, for example:
-
-```toml
-[build]
-target = ["aarch64-apple-ios-macabi", "x86_64-apple-ios-macabi"]
+The targets are distributed through `rustup`, and can be installed using one
+of:
+```console
+$ rustup target add aarch64-apple-ios-macabi
+$ rustup target add x86_64-apple-ios-macabi
 ```
 
-Using the unstable `-Zbuild-std` with a nightly Cargo may also work.
+### Sanitizers
+
+Due to CMake having poor support for Mac Catalyst, sanitizer runtimes are not
+currently available, see [#129069].
