+
+## Text animations
+
+Based on `useCurrentFrame()`, reduce the string character by character to create a typewriter effect.
+
+## Typewriter Effect
+
+See [Typewriter](assets/text-animations-typewriter.tsx) for an advanced example with a blinking cursor and a pause after the first sentence.
+
+Always use string slicing for typewriter effects. Never use per-character opacity.
+
+## Word Highlighting
+
+See [Word Highlight](assets/text-animations-word-highlight.tsx) for an example for how a word highlight is animated, like with a highlighter pen.
