The text plays on the common saying 'If at first you don't succeed, try, try again,' but humorously substitutes the end of the saying with 'call it Version 1.0', which is a reference to software versioning where the first, often imperfect, release of software is labeled as version 1.0. This creates a humorous reinterpretation of the original saying.
If at first you don ' t succeed , call it Version 1 . 0
