 installation of LLVM gets picked up correctly. We recommend adding it to
 your shell profile.
 ```shell
-export LLVM_DIR=$($(brew --prefix llvm@15)/bin/llvm-config --cmakedir)
+export LLVM_DIR=$($(brew --prefix llvm@17)/bin/llvm-config --cmakedir)
 ```
 
 If you don't usually use the `clang` from your Homebrew installation as
 your default compiler, you can set the following CMake flg to use these
 `clang` and `clang++`:
 ```shell
--DCMAKE_C_COMPILER="$(brew --prefix llvm@15)/bin/clang" \
--DCMAKE_CXX_COMPILER="$(brew --prefix llvm@15)/bin/clang++"
+-DCMAKE_C_COMPILER="$(brew --prefix llvm@17)/bin/clang" \
+-DCMAKE_CXX_COMPILER="$(brew --prefix llvm@17)/bin/clang++"
 ```
 Once again, we recommend adding them and other llvm binaries to your
 `PATH` in your shell profile:
 ```shell
-export PATH="$(brew --prefix llvm@15)/bin:$PATH"
+export PATH="$(brew --prefix llvm@17)/bin:$PATH"
 ```
