Last year we used this resource from Desiring God as we prepared for Resurrection Sunday. As you will read in the introduction, these can be done weekly beginning at Lent, or daily beginning on the Saturday of Palm Sunday weekend (the weekend before Easter). This article also gives instructions for lighting candles along with the reading if you choose to add that to your devotion time. I highly recommend using the candles because it is a helpful visual aid. As you get closer to Good Friday, there will be less and less candles lit. The last one gets blown out on Friday. None are to be lit on Saturday. Then on Sunday morning, all are relit!
