Some editors, including JOSM and ID, have "presets". The user clicks a button and fills a form, and the editor applies the proper tags to the element automatically. This can be far easier for beginners than working with raw tags, but it doesn't cover all existing tags. Please note that as beginner, you don't have to dig too deep into precise tagging schemes thanks to presets, but knowing a bit about tags is very helpful. Feel free to skim through the rest of this section if you're in a hurry. Most tag keys and values have their own dedicated page on this Wiki that explains how to use them. Search for what you're trying to map using the search bar and you may find the appropriate tag. If you fail to find it, feel free to ask others for help. Some tags can be used for nodes, ways, and relations. Others can only be used on nodes or ways. A tag's page usually explains this.
