New Django User-Modifying templates

[413jonnn]

Hi, I am a new user to Django.  I recently downloaded and installed a calendar app called "Happenings". I would like to incorporate that into my app and would like to modify several things in the Happenings app. When I go to the admin page, I see the Happenings app listed and it works ok but as stated above, I would like to begin modifying some things.  However, I am unsure how to really do this properly.  The Happenings folder is in a totally separate directory than the app I am creating and I think I'm beginning to get a little lost in all of the different files.  Just having a hard time keeping track of all the pieces I think.  Any tips or guidance on how I should go about this would be great!  Thanks.
