+This rule uses Svelte compiler to check the source code.
+
+<eslint-code-block>
+
+<!--eslint-skip-->
+
+```svelte
+<script>
+  /* eslint @ota-meshi/svelte/valid-compile: "error" */
+  let src = "tutorial/image.gif"
+</script>
+
+<!-- ✓ GOOD -->
+<img {src} alt="Rick Astley dances." />
+
+<!-- ✗ BAD -->
+<img {src} />
+```
+
+</eslint-code-block>
+
+Note that we exclude reports for some checks, such as `missing-declaration`, which you can check with different ESLint rules.
