+# PPTX Support

+LlamaIndexTS now supports pptx files!
+
+## Loading PPTX Files
+
+To load a pptx file, you can use the PptxReader class. Here's an example:
+
+\`\`\`typescript
+import { PptxReader } from 'llamaindexts';
+
+const reader = new PptxReader();
+const nodes = reader.read('path/to/your/file.pptx');
+\`\`\`
+
+## Querying PPTX Files
+
+Once you've loaded a pptx file, you can query it just like any other file. Here's an example:
+
+\`\`\`typescript
+import { QueryEngine } from 'llamaindexts';
+
+const engine = new QueryEngine();
+const results = engine.query('your query here');
+\`\`\`
