This part of the site covers simanim 242 to 365 of the Shulchan Aruch, Orach Chayim, grouped under “Hilkhot Shabbat” (in Sefaria's index, the section הלכות שבת covers simanim 242 to 344, and הלכות עירובין simanim 345 to 395), then, from siman 366, Hilchos Eruvin. We progress in the order of the Mechaber. The simanim below are available; others will be added as the study progresses.
For each siman: full Hebrew text of the Choulchan Aroukh + Hagahah of the Rama, translation and explanation, sources from the Rishonim and Acharonim, plus the pilpul of the great commentators (Mishna Brura, Choulchan Aroukh of the Admour HaZaken, Yabia Omer, Igrot Moshe…).
