S-Corp elections was not filed on time.  How do I go about filing a late S-Corp election with the first year tax return?  

 I have read this needs to be included at the top of the tax return "FILED PURSUANT TO REV. PROC. 2013-30.".  I entered in the reasonable cause sections that the company's president neglected to file form 2553 on time and he did not know advanced notice was required.  Is that all that needs to be included?  Are there other steps to assure the election is approved?
