It explains that the first conditional uses "if" plus the present simple for the if-clause and will/won't plus the infinitive for the result clause. Examples are given such as "If I pass all the subjects, I'll travel to London" and "If I don't do my homework, I won't go to the concert." The document also includes exercises for learners to complete using the first conditional structure.
