[Koha] warning message

[Igbudu Tersoo]

Hi,
i am using koha 17.11 and mysql ver 15.1 Distrib 10.0.36-MariaDB. on the
about koha - system information - preferences and parameters page, there is
an error message "*Warning You are missing the <template_cache_dir> entry
in your koha-conf.xml file. That will bring a performance boost to enable
it.*"

please can someone outline the steps on how to resolve this issue?
Thank you.
