My biggest tip is to bookmark the https://clojure.org/guides/weird_characters page where you can decode Clojure’s syntax sugar.
Another getting started guide includes a helpful table of Clojure’s syntax sugar in it’s section Clojure Syntax.
An excellent way to learn to read Clojure code when first starting out is to solve the problems at http://exercism.io/languages/clojure/about while using clojuredocs.org to lookup functions (it has great examples). Once you solve the problem, you gain access to see other’s answers. You can see my answers (@webappzero) but you should review several other coder’s work and you will gain an eye for elegant solutions quickly.
The challenge with “reading” Clojure code is that Clojure excels at data manipulation so it’s important to “read” code by cloning GitHub repos and executing code in your Clojure REPL. I will follow up soon with a link here to live video showing the process. All this will be in pathwayclojure.org too.
