Installation on galaxy note 10 +

I purchased a refurbished Galaxy note 10 + (SN-N975F/DS).

I noticed the installation instructions here : iodéOS installation - iodé

But, they seem rather simple compared to instructions for lineageos on which iodeos is based.

Could anyone who installed iodeos on this phone confirm me the exact steps to install iodeos ? from the stock firmware.

Regards
