Since Lightroom edits images parametrically, the develop settings are stored in the metadata. You can "save" the develop settings using Metadata -> Save Metadata to File. This will save the data for the selected image to the XMP sidecar file, or the DNG file if you're using that format. If more than one image is selected, the changes will be saved for all the selected images. This will allow the metadata tol follow the image if you move it along with it's XMP file.
