We will give a general overview of the plethora of concordance invariants which can be extracted from Ozsváth-Szabó-Rasmussen's knot Floer homology.
We will then focus on the $\nu^+$ invariant and prove some of its useful properties.
Furthermore we will show how it can be used to obstruct the existence of cobordisms between algebraic knots.
