The deployment/release process is handled by Leiningen. Once set up, you can release a new version of Leona with the following command:
lein releaseBefore we can lein release there are two things that need to be set up.
You need to have the GPG tools installed and a valid key created. For Mac I recommend GPG Suite. For Linux, use your package manager of choice. The tool you use will determine how you actually create a key, so follow the instructiions provided to you.
You need to encrypt your Clojars credentials as described in the following document.

One thing to be aware of is that the document uses https://repo.clojars.org as the address for Clojars, whereas Leona specifies https://clojars.org/repo so use the latter instead.
You need to be added to the workshub organisation on Clojars. Ask another admin to add you.
