+See if there's a [pattern](https://github.com/check-spelling/check-spelling/wiki/Configuration-Examples:-patterns) that would match it.
+
+If not, try writing one and 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.

+<details><summary>it relates to a binary-ish string</summary>
+
+Please add a file path to the `excludes.txt` file instead of just accepting the garbage.
+
+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).
