+# Comment management is handled through a secondary job, for details see:
+# https://github.com/check-spelling/check-spelling/wiki/Feature%3A-Restricted-Permissions
+#
+# `jobs.comment-push` runs when a push is made to a repository and the `jobs.spelling` job needs to make a comment
+#   (in odd cases, it might actually run just to collapse a comment, but that's fairly rare)
+#   it needs `contents: write` in order to add a comment.
+#
+# `jobs.comment-pr` runs when a pull_request is made to a repository and the `jobs.spelling` job needs to make a comment
+#   or collapse a comment (in the case where it had previously made a comment and now no longer needs to show a comment)
+#   it needs `pull-requests: write` in order to manipulate those comments.
+
+# Updating pull request branches is managed via comment handling.
+# For details, see: https://github.com/check-spelling/check-spelling/wiki/Feature:-Update-expect-list
+#
+# These elements work together to make it happen:
+#
+# `on.issue_comment`
+#   This event listens to comments by users asking to update the metadata.
+#
+# `jobs.update`
+#   This job runs in response to an issue_comment and will push a new commit
+#   to update the spelling metadata.
+#
+# `with.experimental_apply_changes_via_bot`
+#   Tells the action to support and generate messages that enable it
+#   to make a commit to update the spelling metadata.
+#
+# `with.ssh_key`
+#   In order to trigger workflows when the commit is made, you can provide a
+#   secret (typically, a write-enabled github deploy key).
+#
+#   For background, see: https://github.com/check-spelling/check-spelling/wiki/Feature:-Update-with-deploy-key
+
+# SARIF reporting
+#
+# Access to SARIF reports is generally restricted (by GitHub) to members of the repository.
+#
+# Requires enabling `security-events: write`
+# and configuring the action with `use_sarif: 1`
+#
+#   For information on the feature, see: https://github.com/check-spelling/check-spelling/wiki/Feature:-SARIF-output
+
+# Minimal workflow structure:
+#
+# on:
+#   push:
+#     ...
+#   pull_request_target:
+#     ...
+# jobs:
+#   # you only want the spelling job, all others should be omitted
+#   spelling:
+#     # remove `security-events: write` and `use_sarif: 1`
+#     # remove `experimental_apply_changes_via_bot: 1`
+#     ... otherwise adjust the `with:` as you wish
