Common uses

The present continuous is used in several instances.

To describe something which is happening at the exact moment of speech:

The boy is crying.

To describe an action that is taking place now, but not at the exact moment of speech:

He is working in Dubai.

To describe an event which is planned in the future:

I'm resitting my French exam on Tuesday.

With always, but meaning often:

My mother is always making me go to school!

She is always playing with that doll!

Formation

To form the present continuous, one uses the appropriate conjugation of to be from the present simple and puts the present participle of the chosen verb after. For example:

He is playing

When using the interrogative with the present continuous, one does not use the verb to do as with the present simple, rather, one swaps the positions of the conjugation of to be and the present participle. For example:

Am I annoying you? which is to ask whether I am annoying you.
