A few minutes after checkout you'll receive one email from Clean Slate (licenses@buildcleanslate.com) with the subject "Your Clean Slate Signature download + license key." It contains the two things you need:

• Download button — your theme as a .zip file. The link stays valid for 7 days.
• License key — a code that looks like CS-XXXX-XXXX-XXXX-XXXX. Keep it safe; you'll use it in step 3.

Can't find the email? Check your spam or promotions folder. Download link expired? Enter your license key on the Theme Update page and we'll email you a fresh one — it always contains the latest version.

1. Click the Download button in your email and save the .zip file. Don't unzip it — Shopify needs the zip as-is.
2. In your Shopify admin, go to Online Store → Themes.
3. Click Add theme → Upload zip file and choose clean-slate-signature.zip.
4. After it uploads, Signature appears in your Theme library. Click Customize to explore it, and Publish whenever you're ready to make it live.

1. Open the Activate License page.
2. Paste the license key from your email.
3. Enter your store's .myshopify.com address — for example my-store.myshopify.com. Not sure what yours is? The activation page has a finder: type your normal domain and it looks it up for you.
4. Click Activate. Done — the theme unlocks on the next page load.

One key activates one store, permanently. Moving to a different store later? Contact support and we'll transfer it for you.

Products are created in your Shopify admin, not in the theme — go to Products → Add product. Everything you create appears in Signature automatically; these habits make the theme shine:

1. Title & description. Write as much as you like — long descriptions can collapse behind a "Read more" link (a Product section setting).
2. Photos — order and alt text matter. The first image is the card photo, the second is the hover image (when enabled), and portrait shots (3:4) fit the default grid best. Most important: set each image's alt text to its color name (e.g. Black) — Signature matches photos to color swatches through alt text, which powers swatch previews and color-cards.
3. Pricing. Set the Price; for a sale, put the original price in Compare-at price — the theme shows the discounted styling automatically.
4. Variants. Add options like Color and Size. The Color option feeds every swatch in the theme; give each variant its matching image. Inventory is tracked per variant, and "Sold out" states appear on cards, pickers and buttons by themselves.
5. Organize. Add the product to collections (grids and menus pull from collections), then use tags: the tag new shows the NEW badge on product cards, and a size-guide tag (e.g. tops) attaches the matching Size Guide Entry to the product page.
6. Save and preview. Open the product on your storefront — the gallery, variant pickers, and buttons are already wired up.

Signature has a built-in size guide system — no app needed, and it works the same in all three product layouts (Product - Spotlight, Product - Gallery and Product - Centered). You build each chart once in the theme editor, and every product picks up the right one automatically through its tags:

1. Turn it on. In the theme editor, open any product page, select your product section in the sidebar, and toggle Enable size guide.
2. Add a Size Guide entry. Click Add block → Size guide. One entry = one chart, so make one per product type — tops, bottoms, shoes, and so on.
3. Give it a Tag ID — for example tops. Then, in your Shopify admin, add that same word as a tag on every product the chart belongs to. That's the whole link: tag tops on the product ⇢ entry with Tag ID tops opens. Matching ignores capitalization.
4. Fill in the chart. Each entry holds optional measurement notes, a chart image, and up to two tables — column headers are comma-separated (Size,Chest,Waist,Hips) and rows go one per line with comma-separated values. You can also attach a Shopify page or custom HTML at the bottom for fully custom guides.
5. Add a fallback (recommended). Create one extra entry and leave its Tag ID blank — it becomes the catch-all shown on any sized product that has no matching tag, so nothing ever slips through without a guide.

One rule to remember: the size guide only appears on products that actually have a Size variant option. That's deliberate — accessories and one-size items never show a pointless "Size guide" link. If your option is named something unusual, Spotlight and Centered have a Size option name setting to tell the theme what to look for.

Each layout presents it in its own style: Spotlight puts the link in the size-picker bar and under the description and opens a slide-out drawer, Gallery adds a row alongside the description accordions (you choose its position), and Centered expands the guide in place, right next to the description.

Using Product - Centered and have one odd-fitting product? Give it its own guide with a product metafield: Settings → Custom data → Products → Add definition, namespace custom, key size_guide, type Rich text — whatever you write there overrides the tag matching for that product only. Want to see every size guide setting? Open the editor tour below, pick Products, then the Size Guide Entry block.
