Conditional Sentences
These sentences consist of two clauses: the main one and the if-clause, The if-clause expresses a condition for the result stated in the main one.
Depending on the type -zero, first, second or third- they follow some verb correlations that you can see in the examples of this chart
(from:https://www2.estrellamountain.edu/faculty/stonebrink/ESL040/4_types_of_conditionals.htm)
As you may notice in the examples, when you put the if clause first, you need to write a comma immediately after. This is not necessary if the main clause comes first, as it is its 'natural' place.

Here is an example with present continuous in the if-clause and an emphatic connector: not only if but even if.
