how do I know which linux OS I can install on a pinetab

[rhanksjr]

I am currently learning about the pine tab.  

Is it restricted to running only Ubuntu Touch?  

Were I to purchase one, how would I know which linux distributions I could install on it?  And, how would I learn how to install each one?  

I'm very confused on these questions.  I read a lot that the pint tab will run linux distributions, but I have not seen anyone describe how to do that.

Please review the Pine64 Pinetab Wiki as a start: https://wiki.pine64.org/index.php/PineTab. The OS section needs updating as Manjaro has done some work as well that may work on the Pinetab. Lastly, there are a few demo YouTube videos, but I would expect more as the early developer batch is received by users.

The wiki will probably undergo a rewrite once the early adopter batch is received as well. Usually for installing on OS on an SD card, you can use Etcher. The PinePhone wiki from Pine64 has detailed instructions (NOOB guide) at https://wiki.pine64.org/index.php?title=...roSD_Cards that should help you understand this better. In practise, it isn't hard to do, and is similar to putting a Linux iso image on a bootable USB.
