Running Boot on Atom - boot-clj/boot GitHub Wiki
When using Atom use the ProtoRepl plug-in.
proto-repl uses lein by default but there is a switch in the settings to turn it off. If no project.clj (the lein configuration file) then proto-repl will fall back to 'build.boot'. The 'build.boot' should be constructed according to the template found in ProtoReplDemo.
