## Delete Document
`delete()` method allows you to delete a document previously added to the app.
### Usage
```python
from embedchain import App
app = App()
forbes_doc_id = app.add("https://www.forbes.com/profile/elon-musk")
wiki_doc_id = app.add("https://en.wikipedia.org/wiki/Elon_Musk")
app.delete(forbes_doc_id) # deletes the forbes document
```
<Note>
If you do not have the document id, you can use `app.db.get()` method to get the document and extract the `hash` key from `metadatas` dictionary object, which serves as the document id.
</Note>
## Delete Chat Session History
`delete_session_chat_history()` method allows you to delete all previous messages in a chat history.
### Usage
```python
from embedchain import App
app = App()
app.add("https://www.forbes.com/profile/elon-musk")
app.chat("What is the net worth of Elon Musk?")
app.delete_session_chat_history()
```
<Note>
`delete_session_chat_history(session_id="session_1")` method also accepts `session_id` optional param for deleting chat history of a specific session.
It assumes the default session if no `session_id` is provided.
