+## Add Dataset
+
+- This step assumes that you have already created an `App`. We are calling our app instance as `naval_chat_bot` 🤖
+
+- Now use `.add` method to add any dataset.
+
+```python
+naval_chat_bot = App()
+
+# Embed Online Resources
+naval_chat_bot.add("https://www.youtube.com/watch?v=3qHkcs3kG44")
+naval_chat_bot.add("https://navalmanack.s3.amazonaws.com/Eric-Jorgenson_The-Almanack-of-Naval-Ravikant_Final.pdf")
+naval_chat_bot.add("https://nav.al/feedback")
+naval_chat_bot.add("https://nav.al/agi")
+
+# Embed Local Resources
+naval_chat_bot.add(("Who is Naval Ravikant?", "Naval Ravikant is an Indian-American entrepreneur and investor."))
+```
+
+The possible formats to add data can be found on the [Supported Data Formats](/advanced/data_types) page.
