There are a lot of ways to easily configure the CIDER experience and these are covered in the http://docs.cider.mx pages. I created a reference page for all the configuration variables as a way to quickly look them up. https://practicalli.github.io/spacemacs/reference/cider/configuration-variables.html CIDER Variables can be applied to all projects by adding them to the clojure layer as layer variables, or in dotspacemacs/user-config section of .spacemacs. For project specific configuration. add these vairables to a .dir-locals.el in the root of a Clojure project. https://practicalli.github.io/spacemacs/clojure-projects/project-configuration.html

You can also use SPC SPC customize to set these CIDER variables, which will add changesto the end of the .spacemacs file
