Thanks @Francois_Ifitwala, @revant_one, @Peter, @jof2jc, @kirthi, @vivek for your comments.
I notice that people love the fact that we are doing things in the open source spirit and also complain documentation is a common problem.
We are doing our best to update it but I also think that the true “open source” spirit is in collaboration. I would love some of those who are building businesses on erpnext to help us build a better erpnext. Fighting a lone battle is hard for us and we would love to get all the help we can (and this in turn will help you!)
We started a documentation project (Help Wanted: Spare 1 hr every week -> Fix the ERPNext Documentation) but on-one seemed to help. I hope that changes soon.
Thanks for the feedback though.
