How do we add the Story Points field on the story/task/epic ?

[Deleted user]

I'm trying to add the field of story points on the Task / story but I'm not able to find how to add it. 

Also, how do I find out what version of Jira am I using ? so that I can check KB articles to that particular version since I checked a few articles but all of them were very old.

Any help would be appreciated. Thanks
