This translation is nearly complete! A few areas to improve before merging:

• At the top of the file, the title and excerpt need a translation (replace the TODO).
• The headings (lines beginning with ## should be translated where applicable.
• Make sure you're not translating the commands or options (like -o) since those don't need to be translated.
