I need help to mount my data drive at boot and dir links from my system ssd to my data sata drive

I need help how to mount my data drive at boot and dir links from my system ssd to my data sata drive.
Firstly, if I seem to be writing peculiarly please correct me. On Sunday 11th Feb, whilst driving, I had a stroke and a blood clot formed on the left side of my brain. The clot screwed up my left and right, at 60kph instead of pulling off to the left, I turned right into a concrete lane divider and rote my car off.

The Neurological Doctors said get back to using your mind as quickly as possible. So here I am.

Now what I want is to mount my data drive at boot. Also I want to have links from system drive to data drive. Before all this went side-ways I had found a number of articles moving my home dir to another drive. But this is no good because I use Timeshift and if you move the home dir all the config dirs and files move. And I created quite a mess.

All inputs apreciated.

These will provide a guide to mounting your data drive at boot

And this will provide info on how to symlink data from your data drive into your home
