finish missing webpage contents

[Gavin1937]

• Home page:
  • the "read more" section in homepage is filled with dummy text. We should remove them and finish that section
• Contact page:
  • the contact page is a dummy page now, we should add something on it
  • maybe we can use client config file to save an email in our local machine, and use that value in contact page. So, in this way, we don't have to push our email address to github repo
