+# Worked Example: Adding a Component
+
+## Scenario
+
+User wants to add a shimmer light sweep effect to their title text.
+
+## Steps
+
+### 1. Install the component
+
+```bash
+hyperframes add shimmer-sweep
+```
+
+### 2. Read the snippet
+
+Open `compositions/components/shimmer-sweep.html` and read the comment header.
+
+### 3. Wire into your composition
+
+**HTML** — wrap target elements:
+
+```html
+<div class="shimmer-sweep-target" style="--shimmer-color: rgba(255, 255, 255, 0.5)">
+  <h1 class="title">AI-Powered Video</h1>
+</div>
+```
+
+**CSS** — paste the `.shimmer-sweep-target` and `.shimmer-mask` rules from the snippet.
+
+**JS** — paste the auto-injection script (before timeline code):
+
+```js
+document.querySelectorAll(".shimmer-sweep-target").forEach((el) => {
+  if (!el.querySelector(".shimmer-mask")) {
+    const mask = document.createElement("div");
+    mask.className = "shimmer-mask";
+    el.appendChild(mask);
+  }
+});
+```
+
+**Timeline** — add the sweep:
+
+```js
+tl.fromTo(
+  ".shimmer-sweep-target",
+  {
+    "--shimmer-pos": "-20%",
+  },
+  {
+    "--shimmer-pos": "120%",
+    duration: 1.2,
+    ease: "power2.inOut",
+    stagger: 0.15,
+  },
+  1.5,
+);
+```
+
+### 4. Lint and preview
+
+```bash
+hyperframes lint
+hyperframes preview
+```
+
+### 5. Customize
+
+- `--shimmer-color`: highlight color per element
+- `--shimmer-width`: light band width (default 20%)
+- `--shimmer-angle`: sweep direction (default 120deg)
+- Timeline `duration`, `ease`, `stagger`: control speed and feel
