+### Glob Pattern
+
+A glob pattern is a string that specifies sets of filenames with wildcards and special characters. This allows you to match multiple files or directories without specifying each file explicitly.
+
+Here are some examples of glob patterns you can use:
+
+`ctrf/ctrf-report.json` - Matches the exact file ctrf/ctrf-report.json.
+
+`ctrf/*.json` - Matches all .json files in the ctrf directory.
+
+`ctrf/**/*.json`- Matches all .json files in the ctrf directory and its subdirectories.
+
+`ctrf/ctrf-report*` - Matches any file starting with ctrf-report (e.g., ctrf-report.json, ctrf-report-old.json).
