Dear community,
As a user of Jira, who creates new issues, I want to be able to write gherkin syntax code (and highlight it that way) in the Description field of a Story.
I found that Description field by default users Wiki Style Renderer and this renderer supports many languages, specified here - https://jira.atlassian.com/secure/WikiRendererHelpAction.jspa?section=advanced
I want to add more languages to the code formatting, such that when I create an issue as shown in picture below....

...shows up formatted similar to what is shown below, after saving /creating it:

How do I enable this in Jira?
(I have admin rights of the Jira instance)
Thanks!
