# 1. Clone the repository. This creates a folder named 'waliyan' inside /app
RUN git clone --depth 1 https://huggingface.co/datasets/devusman/waliyan

# 2. Move the data folder from inside 'waliyan' up to the app's root folder
# This is the equivalent of 'copy' and 'paste'

# 3. Clean up by removing the now-empty 'waliyan' folder
RUN rm -rf waliyan
