Thank you very much!
I struggled a lot to get ERPnext running and this guide just worked perfectly on first try!
I have 2 questions maybe you can answer.
1) I can see 12 new dockers now all related to erpnext. Was that supposed to happen? I set all except of "configurator" to "autostart".
2) How should I go about updating this erpnext installation to the newest version?
