docs.yml

# Publishes docs/ to both documentation homes:
#   - GitHub Pages (Jekyll site, just-the-docs theme), and
#   - the GitHub wiki, kept in sync from the same files.
#
# docs/ is the single source of truth. Do not edit the wiki by hand; the wiki
# job copies docs/*.md over (index.md becomes Home.md, Jekyll front matter is
# stripped), adds WhatsNew.md, and pushes. _Sidebar.md is wiki-only and is left
# alone. Requires a repository secret named WIKI_TOKEN (classic PAT with the
# "repo" scope, or a fine-grained PAT with Contents: Read and write) because
# GITHUB_TOKEN cannot push to the wiki repository.
#
# Before the Pages deployment can run, enable Pages in the repository:
#   Settings -> Pages -> Source: "GitHub Actions" -> Save
# (Alternatively, no workflow is needed at all: Settings -> Pages ->
#  Source: "Deploy from a branch" -> Branch: master -> Folder: /docs.)
