+
+1. Go to "Flakeguard - Test results for automated ticket creation" Report
+2. Select last 7 days
+3. Export it as CSV and download the file
+
+##### Run
+
 ```
 go run main.go create-tickets --jira-project=<JIRA_PROJECT_KEY> --flaky-test-json-db-path=<PATH_TO_FLAKY_TEST_DB_JSON> --assignee-mapping=<PATH_TO_JIRA_ASSIGNEE_MAPPING_JSON> --csv-path=<PATH_TO_CSV_FILE> [--skip-existing] [--dry-run]
