Dúvida sobre Course Press

I hope you understand me because I am using an online translator.

My doubts:

1: In the description of the plugin says that the theme is included. I installed the plugin through the panel and can not find the theme.
2: I did not locate the plugin manual by teaching the setup steps.
3: I created a page and used the recommended shortode. In this page the following text appears in English: "Please select a course you want to enroll in."
Where do I translate the content of texts?
4: Is there a translation of the Brazilian Portuguese plugin?

I await an answer.

Yours sincerely,
