Hi,
I started the following toturial last year:
https://www.erp5.com/developer-Howto.Bootstrap.ERP5.Project
I published the tutorial as is. It includes some changes requested
by Jean-Paul, but I am not sure if the rest is correct. Therefore I would
like to request other slapos and erp5 developers to review and extend it. It
would also be great if someone from slapos community could link to it from
slapos community website as suggested by Rafael.
