Very nice, thank @trducng. Just had some small comments.

Also please update the docs and screenshots:

• https://github.com/Cinnamon/kotaemon/blob/main/docs/usage.md (step 3, guide them to select file index)
• https://github.com/Cinnamon/kotaemon/blob/main/docs/images/chat-tab.png

oh yes, would be nice if you could copy-paste the docs/usage.md file to that one. That one is currently used for hf hub deployment only so it's not that important.

@lone17 I have updated, please check.

LGTM.

One question though, should we auto select any newly added file ? If yes then let's address it in another PR, else please close #26.

I think we should keep the file selection explicit, since our app isn't a question answering demo, but a long-running app.
