 You can build static and shared-libraries, as well as the include headers by simply running:
 
 ```sh
-cargo build [--release] [--features default-engine]
+cargo build [--release]
 ```
 
 This will place libraries in the root `target` dir (`../target/[debug,release]` from the directory containing this README), and headers in `../target/ffi-headers`. In that directory there will be a `delta_kernel_ffi.h` file, which is the C header, and a `delta_kernel_ffi.hpp` which is the C++ header.

 Note that prior to building these examples you must build `delta_kernel_ffi` (see [the FFI readme] for details). TLDR:
 ```bash
