+## Format supported
+
+We support the following formats:
+
+* Youtube Video
+
+To add any youtube video to your app, use the data_type (first argument to `.add`) as `youtube_video`. Eg:
+
+```python
+app.add('youtube_video', 'a_valid_youtube_url_here')
+```
+
+* PDF File
+
+To add any pdf file, use the data_type as `pdf_file`. Eg:
+
+```python
+app.add('pdf_file', 'a_valid_url_where_pdf_file_can_be_accessed')
+```
+
+Note that we do not support password protected pdfs as of now.
+
+* Web Page
+
+To add any web page, use the data_type as `web_page`. Eg:
+
+```python
+app.add('web_page', 'a_valid_web_page_url')
+```
