Normal forms of ADE singularities

Given a two dimension hypersurface $X:f(x,y,z)=0\subset \mathbb{A}^{3}_{\mathbb{C}}$ with only ADE singularities, how does one determine the correct singularity type of $X$ by computing the normal forms of $X$?

Does a similar procedure also exist in positive characteristic?
