PtoS project is a notebook to contain the pre-notes to EGA(/SGA) (see this). Please write to aayushverma6380@gmail.com for any typos and comments. In spirit, it is an evolving notebook subject to regular updates (which will contain provisional sections and likely unfinished threads). The following is a (tentative) plan and the content table of the notes.
