 To add any doc/docx file, use the data_type as `docx`. `docx` allows remote urls and conventional file paths. Eg:
 
 ```python
+from embedchain import App
+
+app = App()
 app.add('https://example.com/content/intro.docx', data_type="docx")
-app.add('content/intro.docx', data_type="docx")
-```
+# Or add file using the local file path on your system
+# app.add('content/intro.docx', data_type="docx")
+
+app.query("Summarize the docx data?")
+```
