I'm having trouble figuring out how to use punctuation marks in my writing. Can you give me a hand?

Sure, I can help! First of all, let's make sure that we're on the same page about what punctuation is and what it does. Punctuation marks are used to indicate the structure of sentences, such as the end of a sentence or the beginning of a new thought. They also serve to connect words together into phrases and clauses. For example, if you wanted to say “the dog ran away”, you could write it like this: The dog ran away.
