Customize frappe framework html layout
If anyone stumbles on this.  The command needed is bench build.  That will compile any assets related to the build.json file in the public folder.  (NOTE: You usually have to create build.json yourself).
ERPNext + frappe need to change layout(footer & header) front-end. I tried to change base.html(frappe/templates/base.html) but nothing happened. Probably this is due to the fact that the html files need to somehow compile. Maybe someone have info how to do it?
UPDATE:
No such command "clear-cache".
Commands:
  backup
  backup-all-sites
  config
  get-app
  init
  migrate-3to4
