+One problem with style guides is that it's often hard to remember all the guidelines
+and to apply them consistently. We're only humans, after all. Fortunately,

+=== Code Formatters
+
+While most Clojure editors and IDEs can format the code, according to the layout guidelines
+outlined here, it's always handy to have some command-line code formatting tools. There are
+a couple of options for Clojure that do a great job when it comes to formatting the code
+as suggested in this guide:
+
+* https://github.com/weavejester/cljfmt[cljfmt]
+* https://github.com/kkinnear/zprint[zprint] (the documentation for configuring it to use the community formatting rules is https://github.com/kkinnear/zprint/blob/master/doc/options/community.md[here])
+
+NOTE: When it comes to editors - Emacs's `clojure-mode` by default will format the code exactly as outlined in the guide.
+Other editors might require some configuration tweaking to produce the same results.
