92 Beretta 3.1 how to change alternator?

My son's 92 Beretta (3.1 engine) needs a new alternator. He's in college with no money, and I am unemployed, so neither of us can afford to pay someone. I have mechanical skills and good tools, so need the step by step instructions if anyone can help! Thank you in advance.

Disconnect the battery, Remove the serp belt (tensioner is below the alternator), unbolt the alternator, unplug the connector, remove the large battery cable from the back of the alternator.

Make sure the battery is good and fully charged!!

Thank you Airjer! I am going to do just that.
