    Mention sponsoring at start of Join preparations
    
    Potential contributors often complain
    that the joining process is too complicated.
    Most probably the sponsorship process is the main cause for this,
    because it does not have definite steps to follow.
    Adding a brief note about the process right in the beginning,
    so that it does not come as a surprise later.
