Their setup guide [1] is the most comprehensive I've seen for any JS transformer to date. They really want to make it as easy as possible for whatever build tool or workflow the developer chooses. It's also shows the state of the build tools' ecosystem and the effort required if you want support all (9 in all for 6to5!).<p>This looks great though. It's actually the first thing since Browserify that I'll add to my build steps. Great work.<p>[1] <a href="https://6to5.org/docs/setup/" rel="nofollow">https://6to5.org/docs/setup/</a>
