Congratulations and welcome to the forums! You have your first card. That's the best first step.
Next, and for all steps that follow, pay on time (before the due date on the statement) every month. Over time, that is the best thing you can do, bar none.
For a $200 card, if it is your only the discussions of utilization don't apply, just stay within the limit at all times. When you pay, you probably want to ensure the payment is electronic to get there as quickly as possible.
Some people pay multiple times per month, and if your spend rate warrants it, this may be appropriate, otherwise, just make sure you pay by the due date.
After you have the card a few months, you may see a CLI which will make it easier to stay within the limit, and that will also indicate you are making progress. I would not worry too much about specific FICO scores for now, just work to get a CLI as your next goal.
And pay on time
