We have these two versions of ray documentation
Version: 3.0.0.dev0
[https://docs.ray.io/en/master/index.html](https://docs.ray.io/en/master/index.html)
Version: 1.13.0
[https://docs.ray.io/en/latest/index.html](https://docs.ray.io/en/latest/index.html)
Somehow I got the feeling that 3.0.0.dev0 is easier to understand. But I can’t find the source code for that version.
Can anybody comment on this?

Hi @krajit
I had the same sensation. I hope that Ray 3.0 will quickly available. But if you like to use now you can install the nightly version:
[https://docs.ray.io/en/latest/ray-overview/installation.html#daily-releases-nightlies](https://docs.ray.io/en/latest/ray-overview/installation.html#daily-releases-nightlies)
I use version 1.13 but reading 3.0 documentation. It’s similar to use, but you need to pay attention to the change of directories.

Hi @hermmanhender
Thanks for the explanation.
“I use version 1.13 but reading 3.0 documentation.”
It is like 1.13 is your target network and 3.0 is the learning network 🙂
