[Rspamd-Users] Directories Missing (Atleast in Docker build)

[E R]

According to https://docs.rspamd.com/getting-started/understanding-rspamd/
I should have three folders relating to modules (just started reading
the documentation):

Module defaults: /etc/rspamd/modules.d/module_name.conf
Local overrides: /etc/rspamd/local.d/module_name.conf
Complete replacement: /etc/rspamd/override.d/module_name.conf

These do not exist in the docker build.  I found a folder
/usr/share/rspamd/config/modules.d/ which appears to have module
configuration files.
1.  Should I create a symbolic link in /etc/rspamd/ to point to this location?
2.  Should I create the two other missing folders so I can use them to
configure things as I would tend to think there should not be anything
writeable under /usr?
