 * `--ignore` or `-i`, ignore a glob pattern, and not look for tests there
 * `--expose-gc`, exposes the gc() function to tests
 * `--pattern` or `-p`, run tests matching the given glob pattern
+* `--reporter` or `-r`, set up a reporter, use a colon to set a file destination. Default: `spec`.
+
+## Reporters
+
+Here are the available reporters:
+
+* `md`: creates a markdown table, useful for setting up a Summary in your GitHub Action
+* `gh`: emits `::error` workflow commands for GitHub Actions to show inlined error. Enabled by default when running on GHA.
+* `tap`: outputs the test results in the TAP format.
+* `spec`: outputs the test results in a human-readable format.
+* `dot`: outputs the test results in a compact format, where each passing test is represented by a ., and each failing test is represented by a X.
+* `junit`: outputs test results in a jUnit XML format
+
+## GitHub Action Summary
+
+The following will automatically show the summary of the test run in the summary page of GitHub Actions.
