First you need to login as admin, the default User Name is: admin and the password should be: 123456
Once logged in you will have enable edit button down the bottom of the page, click on enable editing, this will give you more editing options, check under the top navigation bar, you should have 3 extra menus and 2 dropdown menus.
To edit the front page, you will notice edit buttons above each group of text, this will give the option to edit the text of each section.
You may also want to change the default password as well, while your in edit mode, you will notice the there is a dropdown menu that says: manage, click the dropdown menu and select, My Profile and change password.
Good Luck with metadot, let me know how you go
