yum.postgresql.org & PostGIS question

At the top of yum.postgresql.org it says:

> PostgreSQL RPM Building Project - Yum Repository

> You will find details on PostgreSQL related RPMs for Fedora / Red Hat / CentOS / Scientific Linu / Oracle Linux / Amazon AMIx, like pgAdmin, Slony-I, PostGIS, etc.
I see NO information about PostGIS.
I clicked on release 10 and see nothing about PostGIS there.
(I also checked your https://yum.postgresql.org/files/PostgreSQL-RPM-Installation-PGDG.pdf - it was last updated in 2007...)

If someone installs 10 on CentOS 7, do they get PostGIS?
Or what version of PostGIS is compatible and how do they install it?

https://postgis.net/install/
Has instructions for installing PostgreSQL 9.5 and PostGIS 2.2 - are those the latest for CentOS 7?
We've been advised to install PostGIS 2.3.4. (and PostGres 9.5.10)

Thanks,
