Our first steps tour and our frequently asked questions will help you a lot after registration. They explain how to customize the interface (for example the language), how to upload files and our basic licensing policy (Wikimedia Commons only accepts free content). You don't need technical skills in order to contribute here. Be bold contributing here and assume good faith for the intentions of others. This is a wiki—it is really easy.
When picking categories, try to choose a specific category ("Astronomical diagrams") over a generic one ("Illustrations"). Pro-tip: The CommonSense tool can help you find the best category for your image.
Thanks again for your uploads! More information about categorization can be found in Commons:Categories, and don't hesitate to leave a note on the help desk.
