Candles are added to the hanukkiyah (menorah) from right to left but are kindled from left to right. The newest candle is lit first. (On the Shabbat of Hanukkah, kindle the Hanukkah lights first and then the Shabbat candles.)
Light the shamash (the helper candle) first, using it to kindle the rest of the Hanukkah lights. As you do, say or sing:
Baruch atah, Adonai Eloheinu, Melech haolam, asher kid’shanu b’mitzvotav v’tsivanu l’hadlik ner shel Hanukkah.
Blessed are You,our God, Sovereign of all, who hallows us with , commanding us to kindle the Hanukkah lights.
Baruch atah, Adonai Eloheinu, Melech haolam, she-asah nisim laavoteinu v’imoteinu bayamim hahaeim baz’man hazeh.
Blessed are You, Adonai our God, Sovereign of all, who performed wonderous deeds for our ancestors in days of old at this season.
Baruch atah, Adonai Eloheinu, Melech haolam, shehecheyanu v'kiy'manu v'higiyanu laz'man hazeh.
