Can you explain the mechanism of the reaction (step-by-step) by which the alkene + HBr is changed into an alkyl halide?

The mechanism involves two steps.
In Step 1, the π electrons in the double bond attack the HBr, producing an intermediate carbocation and leaving a negative bromide ion.
In Step 2, the bromide ion then joins to the positive carbon of the carbocation.
