Thank you a lot, @h4ck3rm1k3!

Dear maintainers, please add the instruction NODE_ENV=development node --preserve-symlinks -r babel-register webpack/server.js into Development section.

Development section describes already two methods to run Daedalus with npm

• run with one command
• run these two commands simultaneously in different console tabs

[h4ck3rm1k3]

ok wait. again my bad. mdupont@debian-build-speed:~/experiments/daedalus$ cat runserver.sh NODE_ENV=development node --preserve-symlinks -r babel-register webpack/server.js --host 0.0.0.0
