Think carefully, before taking the risk, see the experiences of other users, see if it can be interesting, or if you can wait to have a new computer later, 100% compatible!
Windows 10 remains one of the best systems, and can be used for quite a while.

I have performed the installation with a compatible computer ..
And I can not take full advantage of the more or less interesting features, because you have to have a certain material
https://www.microsoft.com/en-us/windows/windows-11-specifications
So far, so there is nothing extraordinary about this system
So if the computer is not compatible, you have little interest in using it ..
In some cases, we can have more problem than something else (performance etc), it is better to wait until most of the bugs are solved.
And even better to have a 100% compatible computer, in order to be able to take advantage of the available features
