How do I write a yocto/bitbake recipe to copy a directory to the target root file system

I have a directory of 'binary' (i.e. not to be compiled) files and just want them to be installed onto my target root file system.

I have looked at several articles, none of which seem to work for me.

The desired functionality of this recipe is:

myRecipe/myFiles/ --> myRootFs/dir/to/install

My current attempt is:

SRC_URI += "file://myDir"

do_install() {
         install -d ${D}/path/to/dir/on/fs
         install -m ${WORKDIR}/myDir ${D}/path/to/dir/on/fs
}

I can't complain about the Yocto documentation overall, it's really good! Just can't find an example of something like this!

You just have to copy these files into your target rootfs. Do not forget to pakage them if they are not installed in standard locations.

SRC_URI += "file://myDir"

do_install() {
    install -d ${D}/path/to/dir/on/fs
    cp -r ${WORKDIR}/myDir ${D}/path/to/dir/on/fs
}
FILES_${PN} += "/path/to/dir/on/fs"
