# Prereqs (one-time):
#   1. Create a free account: https://huggingface.co/join
#   2. Create a User Access Token with "write" scope:
#        https://huggingface.co/settings/tokens
#   3. Create an empty Space:
#        https://huggingface.co/new-space
#        - Owner:  your HF username
#        - Name:   ma-rag  (or anything you like)
#        - SDK:    Docker
#        - Hardware: CPU basic (free)
#        - Visibility: Public (or Private if you prefer)
#   4. In that Space's "Settings -> Variables and secrets" add:
#        Secret:  GROQ_API_KEY = gsk_...
#
# Then run:
#   HF_USER=your_hf_username HF_SPACE=ma-rag HF_TOKEN=hf_xxx ./scripts/push-to-hf.sh

===============================================================================
Pushed successfully.

Build logs:  ${PUBLIC_URL} (click "Logs" tab)
Live app:    https://${HF_USER}-${HF_SPACE}.hf.space

The first build takes ~5-8 minutes (it pre-downloads the embedding model into
the image). After it's "Running", the first request triggers auto-ingest of
the Dell docs (~30 seconds) before answering.

Make sure you added the GROQ_API_KEY secret in:
   ${PUBLIC_URL}/settings

If the app logs say 'GROQ_API_KEY is not configured', add/fix the secret and
then click "Restart this Space" on the Settings page.
