---
# How it is organised
#
# - Each doc node is a yaml dict
# - A doc node is either a grouping node or a content node
# - A doc node may have edition: ee for enterprise only content
#
# Grouping node
# - Must have a 'title_en' (English), 'title_cn' (Chinese) is optional wehn no need to translate. e.g. FAQ
# - Parent nodes must NOT have a 'path'
#
# Content node can be one of:
# - Just the path to the markdown file (the first line of which is extracted as its title)
#   the path is relative inside the per-language sub-dir i.e. en_US and zh_CN
# - A node with 'title_en' 'title_cn' and 'path'

- title_en: EMQX Overview
  title_cn: EMQX 概览
  path: './' # this is the index page, {en_US,zh_CN}/README.md is the content
