Specifications! 1. Number of networks for authorization - 4 pieces (Vkontakte, Facebook, Instagram, OK) 2. Ability to edit the welcome page (picture, text, name of the institution) 3. Ability to customize the posted advertising post Vkontakte and Facebook; 4. Ability to specify groups Vkontakte, Facebook, Instagram to join them 5.

I also need documentation on the project. What, where, how, why, why, what is responsible for and so on. This is a long-term project that assumes further development of the functional and technical support after the implementation of the base, so the focus is on long-term relationships. Thank you all for your time. Interested responses from understanding professionals, ideally those who implemented this. In the answer, specify the approximate cost and terms.
