Index copy no longer promises templates or print files for every build.

 ## Adding a build
 
 1. Make a folder for it, named in lowercase with no spaces (`greenman`, `atompunk`). Put its page at `<folder>/index.html`, with its images and downloads inside the folder so its links stay relative.
-2. In the top-level `index.html`, copy a `<li class="build">` block to the top of the list and change the link, image, alt text, title, description and tags. The card image is cropped to 4:3, biased toward the top of the photo.
-3. Run `./deploy -n` to check what will be uploaded, then `./deploy`.
+2. In the top-level `index.html`, copy an `<a class="build">` card to the top of the list and change the link, image, alt text, title and the three lines of text. The newest build carries the extra class `first`, which gives it the full-width card; take `first` off the one it replaces. Card images are cropped to fit, so set `object-position` for the new image as `.greenman` does.
+3. Give the new build's page a link back to the index, as `greenman/index.html` has at its top and bottom: `<a href="../">← Kestrel's Builds</a>`.
+4. Run `./deploy -n` to check what will be uploaded, then `./deploy`.
