You can see the fileds of any object under Fields.If you are in classic go to SetUp--build--customize--contact--fields. I would suggest you read the content from the first unit of the module and then attempt the challenge so that you can learn more.
Please mark it as solved if my reply was helpful. It will make it available for other as the proper solution.
