Describe the feature you'd like

Regarding:
https://www.bookstackapp.com/docs/admin/upload-config/#changing-upload-limits

I've been fighting with the ability to upload large files for years. I set all the options I could think of to increase max file uploads size.
I kept getting:
422 (Unprocessable Content) after uploading anything larger than 768MB

It turns out:
tmpfs on /tmp type tmpfs (rw,relatime,size=786432k)

This was the problem

Describe the benefits this would bring to existing BookStack users

Troubleshooting max file upload sizes

Can the goal of this request already be achieved via other means?

I suppose... but having all the related information in one place is incredibly helpful.

Have you searched for an existing open/closed issue?

I have searched for existing issues and none cover my fundamental request

How long have you been using BookStack?

Over 5 years

Additional context

No response

Thanks @kobaz, I've opened this on the website repo here:
https://codeberg.org/bookstack/website/issues/226
Therefore I'm going to close this issue off since this is more suited to our website.

Out of interest, what OS were you using in this scenario?
