# More detailed description of configuration parameters

Hi,

where could I find a more detailed description of the configuration parameters?

For example, the types a meanings of the different fields in CVMFS_UPSTREAM_STORAGE.
Here, https://cvmfs.readthedocs.io/en/stable/apx-parameters.html?highlight=cvmfs_upstream_storage#server-parameters I only see “Upstream spooler description defining the basic upstream storage type and configuration.”

Is there somewhere a more detailed explanation?

Thanks,
Jose

Hi Jose,

The `CVMFS_UPSTREAM_STORAGE` parameter is a bit tricky. I added more details in an extra section.

Cheers,
Jakob

thanks a lot !!
