where is upstream code for charms displayed?

[Adam Stokes]

For whatever reason I'm having a difficult time figuring out where the
upstream source code is for a charm that I wish to contribute to.

For example, going here: https://jujucharms.com/elasticsearch/trusty/15

What should I be looking for or clicking on that'll take me to a place
where I can begin getting involved with that project? (This should also be
viewed from a perspective where someone is not familiar with Launchpad.)

Also, where's the Code link under the file list heading?
