@font-face {font-family: ‘Merge-Light’;src: url(‘webfonts/235FBE_0_0.eot’);src: url(‘webfonts/235FBE_0_0.eot?#iefix’) format(’embedded-opentype’),url(‘webfonts/235FBE_0_0.woff’) format(‘woff’),url(‘webfonts/235FBE_0_0.ttf’) format(‘truetype’);}

2. the .woff, .ttf and .eot fonts should be in a ‘webfonts’ directory in the site root.

3. this description should be in the top of the theme’s style.css:

/* CHICKENBOY: webfontKIT */
.Merge-Light {
font-family:Merge-Light;
font-weight:400;
font-style:normal;
}

4. If you’re using Headway, then you need to add a little script to the header…
