Perhaps the repository already exists and I just couldn’t locate it at https://github.com/pimcore but would it be possible to share the advanced demo, https://demo-advanced.pimcore.org/admin/, source code in github for instance?
I just installed and this may be useful:
A handy reference:
I configured my database settings in:
app/config/installer.yml (see above .md for details)
And then ran install as follows:
./vendor/bin/pimcore-install --admin-username admin --admin-password ***** --no-interaction
To try again: --ignore-existing-config
I earlier thought that it had failed and hung at 54% but it was actually very busy with an import. So be patient.
