just looking for a simple way to try it out please don't tell me it's not a good idea I know don't care any help would be greatly appreciated

What's wrong with the official documentation? I don't know better way.

when I try to look it up I find youtube videos and Debian homepage talks about bookworm cant find instructions to install it looking for an iso or command lines I can paste in the terminal would be great

You can find it here:

that's a horrible website that makes it look like it's going to tell you how to install 12 gives you 11 not strat forward at all if anyone else having trouble finding bookworm here the copy and paste to upgrade 11 to 12 https://wiki.debian.org/DebianEdu/Do...kworm/Upgrades

that is another thing, the upgrade process. And again, that is the official documentation. Anyway, it looks like your issue is solved.
From the other hand if you have any problems regarding that documentation, if you are stuck somewhere, don't hesitate, but ask.

You don't install Debian 12 because it has not been released.

You can install Debian Testing - which will (in approx two years) become Debian 12 - and the recommended method for that is by installing Debian 11 (stable) then switching the repositories.

However, as per the above page, there are also weekly/daily builds of Testing that may be installed directly (presumably at the risk of the installer not working, hence why it's not the recommended path).

the plan is to upgrade my current OS 4QOS just see what happens I was warned in another post it's a bad idea try it for fun when that falls ill install 11 and upgrade maybe try weekly/daily builds too at some point

You were told it's a bad idea to try it for fun?

It's a bad idea to run Debian Testing as your sole OS or on a computer you somehow rely on, since there's a chance it may break.

But if you run it on a computer where you can either wait for a fix, or repair it yourself, or reinstall, then it's fine.

have 2 PCs also can just swap hard drives clone drives if it bracks, not a big deal to me would definitely not recommend someone to do this if only PC. SSD cheap now so I guess could always have 1 for testing OS

you can have a VM to test things like this.

The most straight forward (AFAIK) is Siduction.
From the site:
Siduction is an operating system based on the Linux kernel and the GNU project. In addition, there are applications and libraries from Debian.
The name siduction is a play on two words. The word sid, which is the codename of Debian Unstable, and seduction in the sense of seduce.

I have used VM in my windows day tried to install VM a couple of months ago on Linux had a small problem don't remember what it was did not really try too hard to get it working I use Clonezilla I rater test at fill power anyways not hard to restore IMG using an old SATA SSD going to buy M.2 then use SATA for testing

thanx updating my 4QOS tonight after it falls apart Siduction sounds interesting maybe give it a go

To install Debian Testing (Bookworm):
Google these keywords ---> Debian installer

The ISO links on that page are always for Testing, which I've been running for some 10 years now as my crutch. The only major breakage I can remember are usually with Plasma, once every couple years or so. The last one was just a month or so ago so Plasma should be good for a while now.

Gentoo and Fedora are usually in a race when it comes to pumping out the latest "stable" versions of packages, Fedora breaks, Gentoo Gnome is stable so far for me. Half of Debian Testing is not far behind them, but the other half of Testing is a lot further behind in versions compared to the "bleeding edge" distributions. Debian has a reputation for being stable, if you're OK with Fedora then you can call Debian Testing stable.
