I learned a lot of helpful things about a cover letter. First I learned what a cover letter even is. A cover letter is a letter sent with, and explaining the contents  of goods. Then I learned that you need three paragraphs to have a cover letter. The first one needs to be about the job you want and your job qualifications. The second paragraph needs to be about why your past experience be good for the job, and just to expand your qualifications if needed. Last paragraph needs to have your contact information and say thank you.
