You deleted all my tuning options here in the README @sayan-biswas .... we need to minially document them, even if they are not specified in the config/base/env/config file

I'm assuming you did this @sayan-biswas because I didn't need to set these defaults when I added the tuning options ? If so, thanks for the correction.

Or was this accidental? ...If it was, in hindsight, I does probably make sense to not set these, even to the defaults. (though 10 does not line up with the default as described in the doc.

Users can always add these to their config map.
