Hola Kacper

The hints are correct. The verbs are all conjugated in the tú form of the imperative, which coincides with the 3rd person singular of the present indicative. In this lesson you will have all the details about how to form the imperative (affirmative) for the informal tú, i.e. an informal command: do this, do that..., of most verbs. The second lesson is for the imperatives that are irrregular and don't follow the general rule:

Imperative affirmative of tú for most verbs

Imperative affirmative of tú for verbs that are irregular

I hope these help.
