 Use `--dry-run` option to see the export before being imported.
 
+By default, it takes description from Toggl / CSV file and combines it into Jira issue key and work log description.
+Therefore, your descriptions should follow the pattern [^(.*?)\s*(?:\((.*?)\))?$](https://regex101.com/r/YUvRCq/1). For
+example these are valid descriptions: `XYZ-8 (resolving conflicts in the PR)`, `XYZ-8`.
+If you are not going to follow this pattern, worry not! You can replace the regex with your own with `DESCRIPTION_REGEX`
+env variable.
