Preliminary support, learning on the go.
First, set up cider-nrepl and vim-fireplace following their respective installation notes. As indicated in fireplace, cljrefactor.vim doesn't provide indenting or syntax highlighting, so you'll want a set of Clojure runtime files if you're on a version of Vim earlier than 7.4. You might also want leiningen.vim for assorted static project support.
If you don't have a preferred installation method, I recommend installing vundle.vim then simply add:
Plugin 'reborg/vim-cljrefactor'
Once help tags have been generated, you can view the manual with :help cljrefactor.
