+# No Main Hand
+
+A simple client-side fabric mod that visually removes the main hand.
+The hand in first person as well as the player model main arm are set to be
+invisible.
+
+Changing the main hand game option decides which arm is hidden.
+The sleeve of the skin can be left enabled or disabled via its vanilla
+setting.
