Community volunteers maintain Getting Started documentation for a number of different tools and approaches. Some of the most commonly used tools include:
Leiningen - an extensible build tool that provides dependency management, REPL support, testing, packaging, deployment, and many other capabilities.
Boot - build tooling for Clojure: instead of a special-purpose DSL, Boot supplies abstractions and libraries you can use to automate nearly any build scenario with the full power of the Clojure language
IntelliJ Cursive
Sublime Text with SublimeREPL
Clojure/conj (usually in November)
Clojure/west (usually in March)
EuroClojure (usually mid-year)
ClojureBridge - beginner workshops for women
