I feel a little bad writing about this, but I know users will be asking for it, so might as well have a proper place for such information and discussion...
Before installing them, be warned:
We do not support the use of non-stable plugins.
You cannot share pedalboards containing such plugins.
You can expect things to break if you install too many of them at random.
You risk your live gig going wrong if you use them live.
With that said, it should be safe if you install 1 or 2 plugins from there, test them first, then slowly use them with some precaution.
If a plugin causes the MOD to become unstable or unpredictable, please uninstall it as soon as possible.
After a plugin proves to be stable, feel free to mention it to us and we'll give it some attention.
If lots of users say the same about the same plugin, we'll do an effort to bring it to the stable section.
Now, you ask, how exactly do we enable non-stable plugins?
Well, it's somewhere on this page:
