+## Terminal API
+
+The `TerminalTUI` component exposes a reactive API for programmatic control via the `terminal` bindable prop.
+
+### Setup
+
+```svelte
+<script lang="ts">
+  import TerminalTUI from '$lib/components/TerminalTUI.svelte';
+  import type { TerminalAPI, TerminalLine } from '$lib';
+  
+  let terminal = $state<TerminalAPI>();
+  let lines = $state<TerminalLine[]>([
+    { type: 'output', content: 'Hello world!' }
+  ]);
+</script>
+
+<TerminalTUI bind:terminal bind:lines title="~/demo" />
+```
+
+### API Methods
+
+#### Writing Lines
+| Method | Description |
+|--------|-------------|
+| `terminal.write(line)` | Append a single line |
+| `terminal.writeLines(lines)` | Append multiple lines |
+| `terminal.clear()` | Remove all lines |
+| `terminal.setLines(lines)` | Replace all lines |
+
+#### Updating Lines
+| Method | Description |
+|--------|-------------|
+| `terminal.update(index, updates)` | Update line by index with partial changes |
+| `terminal.updateContent(index, content)` | Update just the content of a line |
+| `terminal.updateById(id, updates)` | Update line by its `id` property |
+
+#### Removing Lines
+| Method | Description |
+|--------|-------------|
+| `terminal.remove(index)` | Remove line at index |
+| `terminal.removeRange(start, count)` | Remove a range of lines |
+| `terminal.removeById(id)` | Remove line by its `id` property |
+
+#### Inserting Lines
+| Method | Description |
+|--------|-------------|
+| `terminal.insert(index, line)` | Insert line at a specific index |
+
+#### Reading State
+| Method | Description |
+|--------|-------------|
+| `terminal.getLine(index)` | Get line at index |
+| `terminal.getLines()` | Get all lines (copy) |
+| `terminal.getLineCount()` | Get number of lines |
+| `terminal.findById(id)` | Find index of line by id |
+| `terminal.isAnimating()` | Check if typing animation is active |
+
+#### Navigation & Control
+| Method | Description |
+|--------|-------------|
+| `terminal.scrollToBottom()` | Scroll to bottom of terminal |
+| `terminal.scrollToLine(index)` | Scroll to specific line |
+| `terminal.skip()` | Skip current typing animation |
+| `terminal.restart()` | Restart typing animation from beginning |
+
+### Example: Dynamic Updates
+
+```svelte
+<script lang="ts">
+  import TerminalTUI from '$lib/components/TerminalTUI.svelte';
+  import type { TerminalAPI } from '$lib';
+  
+  let terminal = $state<TerminalAPI>();
+  let lines = $state([
+    { type: 'output', content: 'Initializing...', id: 'status' }
+  ]);
+  
+  async function runProcess() {
+    // Update existing line
+    terminal?.updateById('status', { 
+      type: 'info', 
+      content: 'Processing...' 
+    });
+    
+    await delay(1000);
+    
+    // Add progress
+    terminal?.write({ 
+      type: 'progress', 
+      content: '', 
+      progress: 50, 
+      progressLabel: '50%' 
+    });
+    
+    await delay(1000);
+    
+    // Complete
+    terminal?.updateById('status', { 
+      type: 'success', 
+      content: 'Complete!' 
+    });
+  }
+</script>
+
+<TerminalTUI bind:terminal bind:lines />
+<button onclick={runProcess}>Start</button>
+```
+
 ## 3D Model Viewer
 
 The `ModelViewer` component provides an interactive Three.js viewer for `.glb` models.
