# we build the docs in these stages:
# 1. install quarto and python dependencies
# 2. copy files from "source dir" to "intermediate dir"
# 2. generate files like model feat table, etc in "intermediate dir"
# 3. copy files to their right spots (e.g. langserve readme) in "intermediate dir"
# 4. build the docs from "intermediate dir" to "output dir"
