Edit header.tpl and added the following after <title> line

<meta name="keywords" content=" add Keywords here" />

<meta name="description" content="add description here" />

i know how meta tags work but if i change the header meta tags it will change it for the whole site i want to change it for the index page only without messing with the rest of the tags for other pages
