 ### Building
 
-`jextract` depends on the [C libclang API](https://clang.llvm.org/doxygen/group__CINDEX.html). To build the jextract sources, the easiest option is to download LLVM binaries for your platform, which can be found [here](https://releases.llvm.org/download.html) (version 13.0.0 is recommended). Both the `jextract` tool and the bindings it generates depend heavily on the [Foreign Function & Memory API](https://openjdk.java.net/jeps/454), so a suitable [jdk 22 distribution](https://jdk.java.net/22/) is also required.

 The repository also contains a comprehensive set of tests, written using the [jtreg](https://openjdk.java.net/jtreg/) test framework, which can be run as follows (again, on Windows, `gradlew.bat` should be used instead):
 
 ```sh

 Note: running `jtreg` task requires `cmake` to be available on the `PATH`.
