+# Importing assets in Remotion
+
+## The public folder
+
+Place assets in the `public/` folder at your project root.
+
+## Using staticFile()
+
+You MUST use `staticFile()` to reference files from the `public/` folder:
+
+```tsx
+import {Img, staticFile} from 'remotion';
+
+export const MyComposition = () => {
+  return <Img src={staticFile('logo.png')} />;
+};
+```
+
+The function returns an encoded URL that works correctly when deploying to subdirectories.
+
+## Using with components
+
+**Images:**
+
+```tsx
+import {Img, staticFile} from 'remotion';
+
+<Img src={staticFile('photo.png')} />;
+```
+
+**Videos:**
+
+```tsx
+import {Video} from '@remotion/media';
+import {staticFile} from 'remotion';
+
+<Video src={staticFile('clip.mp4')} />;
+```
+
+**Audio:**
+
+```tsx
+import {Audio} from '@remotion/media';
+import {staticFile} from 'remotion';
+
+<Audio src={staticFile('music.mp3')} />;
+```
+
+**Fonts:**
+
+```tsx
+import {staticFile} from 'remotion';
+
+const fontFamily = new FontFace('MyFont', `url(${staticFile('font.woff2')})`);
+await fontFamily.load();
+document.fonts.add(fontFamily);
+```
+
+## Remote URLs
+
+Remote URLs can be used directly without `staticFile()`:
+
+```tsx
+<Img src="https://example.com/image.png" />
+<Video src="https://remotion.media/video.mp4" />
+```
+
+## Important notes
+
+- Remotion components (`<Img>`, `<Video>`, `<Audio>`) ensure assets are fully loaded before rendering
+- Special characters in filenames (`#`, `?`, `&`) are automatically encoded
