If you see a bunch of garbage

If it relates to a ...

well-formed pattern

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.

binary-ish string

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).
