The て-form is also used in the pattern て-form + もいい, which is commonly used to ask for permission or whether something is acceptable. The word いい, as you learned previously, means good or OK. So you can think of the literal translation of this grammar point as, Is it alright to …?
Conversely, you can use the pattern て-form + はいけません to say that something is not permitted. Keep in mind that the て-form + はいけません is a strict way of saying someone can't do something. Later you will learn kinder ways of asking someone to refrain from doing something.
Check out the sentences below for some examples for how this pattern may be used in context.
