-By default the command suggestion will generate a file named based on your commit. That's generally ok as long as you add the file to your commit. Someone can reorganize it later.
-
-:warning: The command is written for posix shells. You can copy the contents of each `perl` command excluding the outer `'` marks and dropping any `'"`/`"'` quotation mark pairs into a file and then run `perl file.pl` from the root of the repository to run the code. Alternatively, you can manually insert the items...
-
-If the listed items are:
-* ... **misspelled**, then please *correct* them instead of using the command.
-* ... *names*, please add them to `.github/actions/spell-check/dictionary/names.txt`.
-* ... APIs, you can add them to a file in `.github/actions/spell-check/dictionary/`.
-* ... just things you're using, please add them to an appropriate file in `.github/actions/spell-check/expect/`.
-* ... tokens you only need in one place and shouldn't *generally be used*, you can add an item in an appropriate file in `.github/actions/spell-check/patterns/`.
-
-See the `README.md` in each directory for more information.
-
-:microscope: You can test your commits **without** *appending* to a PR by creating a new branch with that extra change and pushing it to your fork. The [:check-spelling](https://github.com/marketplace/actions/check-spelling) action will run in response to your **push** -- it doesn't require an open pull request. By using such a branch, you can limit the number of typos your peers see you make. :wink:

-#### :warning: Reviewers
-At present, the action that triggered this message will not show its :x: in this PR unless the branch is within this repository.
-Thus, you **should** make sure that this comment has been addressed before encouraging the merge bot to merge this PR.

+By default the command suggestion will generate a file named based on your commit. That's generally ok as long as you add the file to your commit. Someone can reorganize it later.
+
+:warning: The command is written for posix shells. If it doesn't work for you, you can manually _add_ (one word per line) / _remove_ items to `expect.txt` and the `excludes.txt` files.
+
+If the listed items are:
+
+* ... **misspelled**, then please *correct* them instead of using the command.
+* ... *names*, please add them to `.github/actions/spelling/allow/names.txt`.
+* ... APIs, you can add them to a file in `.github/actions/spelling/allow/`.
+* ... just things you're using, please add them to an appropriate file in `.github/actions/spelling/expect/`.
+* ... tokens you only need in one place and shouldn't *generally be used*, you can add an item in an appropriate file in `.github/actions/spelling/patterns/`.
+
+See the `README.md` in each directory for more information.
+
+:microscope: You can test your commits **without** *appending* to a PR by creating a new branch with that extra change and pushing it to your fork. The [check-spelling](https://github.com/marketplace/actions/check-spelling) action will run in response to your **push** -- it doesn't require an open pull request. By using such a branch, you can limit the number of typos your peers see you make. :wink:
+
+
+<details><summary>If the flagged items are :exploding_head: false positives</summary>
+
+If items relate to a ...
+* binary file (or some other file you wouldn't want to check at all).
+
+  Please add a file path to the `excludes.txt` file matching the containing file.
+
+  File paths are Perl 5 Regular Expressions - you can [test](
+https://www.regexplanet.com/advanced/perl/) yours before committing to verify it will match your files.
+
+  `^` refers to the file's path from the root of the repository, so `^README\.md$` would exclude [README.md](
+../tree/HEAD/README.md) (on whichever branch you're using).
+
+* well-formed pattern.
+
+  If you can write a [pattern](https://github.com/check-spelling/check-spelling/wiki/Configuration-Examples:-patterns) that would match it,
+  try adding it to the `patterns.txt` file.
+
+  Patterns are Perl 5 Regular Expressions - you can [test](
+https://www.regexplanet.com/advanced/perl/) yours before committing to verify it will match your lines.
+
+  Note that patterns can't match multiline strings.

+# 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 commment, 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).
