# markdownlint-cli configuration file.
# To run markdownlint, use the following bash script:
#   bash build_tools/github_actions/lint_markdown.sh <file>

# Enable all markdownlint rules by default
default: true

# List formatting:
#
# 1. Lists must have a blank line before AND after the list.
# 2. Lists start aligned to the left (do not indent the top level list items).
#    NOTE: markdownlint currently checks indentation for unordered lists only.
#          Please manually verify that your ordered lists are not indented.
#          See https://github.com/DavidAnson/markdownlint/issues/138.
# 3. You may use one or zero blank lines between list items.
# 4. Nested list items should be indented to align with the first character of
#    the first line. For bullet lists, that means 2 spaces. For numbered
#    lists, that's 3 spaces (but 4 spaces is okay if that's easier).
# 5. In multiline list items, subsequent lines are indented by 2 spaces.
#    This is not checked automatically, so we're documenting this convention
#    to make sure the codebase stays consistent.
#
# Examples:
#
# * This is a list item that has multiple
#   lines and each line aligns with the text from the first line.
#   * This is a nested list, also aligned with the first line.
#
# For ordered lists, that means three spaces for wrapped lines:
#
# 1. This is an ordered list item.
#    1. The nested list aligns with the first line.
