Translating categories is pretty simple and you'll be able to keep track of what's translated with labels when you've switched to a secondary language.
If you haven't translated a category's information yet you'll see a Needs translation label appear beside the title. Once you've translated that category the label will disappear.

Translating Categories
- Head to Content (or click here)
- Click the account switcher in the top left and pick a language (or type the language's name in search)
- Click the
Category details button on the category row
- Translate the Title, Slug, and Description
- Hit Save changes
Under the Title, Slug, and Description fields you'll see the value in your default language. Click the copy button beside it to copy the original into the field, which is handy for a slug that should match across languages.
