 This version of CPython can be built with an experimental just-in-time compiler[^pep-744]. While most everything you already know about building and using CPython is unchanged, you will probably need to install a compatible version of LLVM first.
 
+Python 3.11 or newer is required to build the JIT.

 ## Installing LLVM
 
 The JIT compiler does not require end users to install any third-party dependencies, but part of it must be *built* using LLVM[^why-llvm]. You are *not* required to build the rest of CPython using LLVM, or even the same version of LLVM (in fact, this is uncommon).

+Otherwise, just configure and build as you normally would. Cross-compiling "just works", since the JIT is built for the host platform.
 
 The JIT can also be enabled or disabled using the `PYTHON_JIT` environment variable, even on builds where it is enabled or disabled by default. More details about configuring CPython with the JIT and optional values for `--enable-experimental-jit` can be found [here](https://docs.python.org/dev/whatsnew/3.13.html#experimental-jit-compiler).
