Help with some PHP, need to add links

Hi everyone, sorry im new to wordpress. Im looking to add my most current links to the new posts on my blog. Im guessing this is done with an include of php some how? Im frustrated i cannot figure this out. I would like to have when i post a new post on my blog the link shows up on my homepage so people can click on it and goes to the appropriate post.
Thanks for all your help in advance 🙂
