Readme doesn't say how to access the file manager

The title sums it up but I don't know how to properly access the file manager after installing this package

it doesn't work out of the box because it installs assets in the app/public/bundles/fmelfinder folder but the default config expects them to be at app/public/assets/bundles/fmelfinder so I set this in the config file

fm_elfinder:
    assets_path: false

Then at the /elfinder route I'm greeted by "Invalid backend configuration. Readable volumes not available."

Having used elfinder before I know this happens when the connector is not setup but I don't know what to do so I try the only other route mentioned in the readme, /efconnect

Connecting to it gives {"error":["errUnknownCmd"]} implying that something is wrong BUT when trying the /elfinder route again it works and this can be reproduced by restarting the symfony server

Sorry for the rant but I'm new to Symfony and this has been frustrating, especially since the installation steps seem to be outdated

The default config has a root with path: uploads and I didn't have this folder... I sorta expected it to default to the "public" folder... I still think the readme could be refined
