# 🧙 Greetings, traveler!
#
# Why are you here?.. Wait, let me guess! You're a DipDup maintainer, something has broken in CI, and you have no idea how the docs are
# built, right? Good news: everything related to building, formatting and linting documentation is in this file. Bad news: we do everything
# with custom scripts, and it's DOOM on Nightmare. There are comments where possible tho. Read them carefully and you'll be fine.
#
# To run `build --serve` command you need to clone and install frontend from private `dipdup-io/interface` repo first.
