I did a translation activity of CakePHP. But I've pulled from git hub and I don't know how to check the rst file

Hi. こんにちは。

As I said in the title, I want to spread the use of this wonderful CakePHP in Japan as well. Currently, there is not a lot of documentation for CakePHP4 in Japan.

Now, let’s get to the point, I pulled from github, but I don’t know how to check the screen of the rst file. Can someone very gently show this poor human how to build an environment?

The one I am trying to translate is the AuthenticationPlugin.
