In the KIS Utilities User Guide, you can find information on the installation, troubleshooting usage issues, explanation of each function of KIS Utilities, examples and scenarios to help you get an idea, etc.
KIS Utilities is written with the end-users in mind and is a powerful utility yet extremely small in size. It is not a small effort to compile a comprehensive documentation. The user who can appreciate that KIS Utilities User Guide is not written to entertain is most likely to harness the full potential of what this software can do for them.
While I couldn't stress enough the importance of reading this User Guide before one starts using the utilities, it would be prudent of you to test the functions on sample data if one must scrimp on the time to read the User Guide and dive straight into its functions.
With that, I hope you will have a good time in using KIS Utilities.
