Giving a Structured Presentation

tout d'abord / ensuite / enfin — sequencing adverbs

English uses a similarly small signpost set ('first, next, finally'), so the concept transfers directly — the main new task is simply learning the French words rather than any new grammar. Note that these structuring adverbs themselves don't take que or trigger any special mood, unlike some of the more complex connectors you'll meet at B2 and C1 that do govern subjonctif.
