Hello,
The easiest way to get started is to start with a platform (rather than a single core like RI5CY), that is a system that includes both the core, and associated peripherals, memory and the interconnect that belongs to it.
If you want to do very basic things, the older PULPino (https://github.com/pulp-platform/pulpino) is a very simple platform, and I would follow the instructions on the github page. This is good, if you are only interested in the core, and not necessarily want to use it as a microcontroller.
If you are planning on using a more complete (and up to date) single core microcontroller I would look at PULPissimo (https://github.com/pulp-platform/pulpissimo). Both of these platforms will use the PULP SDK (https://github.com/pulp-platform/pulp-sdk). There are also several platforms that use multiple cores (like HERO and OpenPULP, but this is probably not needed for you at this stage).
There are other platforms (that are not designed by us) that use RI5CY, like the Greenwaves GAP8 (which has a Platform IO based environment) https://greenwaves-technologies.com/en/sdk/ or open-isa.org that provides its own environment (https://open-isa.org/downloads/).
It is of course also possible to just use the core, but as you point out, it is not very directly accessible (you normally always need it to be part of a platform to do something with it).
I hope this helps a little
