It includes the commandments to: love God, study the Torah, read the Shema prayer(Expressing the unity of God) twice daily, wear Teffilin and affix a Mezuzah on the doorposts.
The mezuzah must be written by a qualified Scribe on parchment made from the skin of a clean animal.

The mezuzah is attached to the upper part of the doorpost at the entrance of each room in a slanting position.
