I'd love to help but can you be more specific? Until then, taking a guess at what you mean exactly: - importing a DNG into the application: in the top-left there's an "import" button and a "folder" button to import files and/or folders. Navigate to the folder with your DNG. Select it, import it, like you'd expect opening files to work - after importing you're still in the "lightroom" section, which is the gallery of all imported photos. On the left you can filter by "film roll", representing photos you imported together. You can also rate selected photos zero to five stars, label them rejected or with a color (all on the bottom row), and then further filter out photos via controls at the top. - to edit a photo you need to go to the "darkroom" view. Either select a photo and click on darkroom, or just double-click. After that, well, there are a lot of options to explore, haha. There's quite a few YouTube tutorials that are a lot better at explaining the interface than a text description here would be. Good luck and have fun!
