+If you don't use `devtools::load_all()`, you'll also need to run `cpp11::cpp_register()` before building the package.
 This function scans the C++ files for `[[cpp11::register]]` attributes and generates the binding code required to make the functions available in R.
 Re-run `cpp11::cpp_register()` whenever functions are added, removed, or have their signatures changed.
-If you are using `devtools` to develop your package this is done automatically by the pkgbuild package when your package has `LinkingTo: cpp11` in its DESCRIPTION file.
