Hi, everyone !

Could you help me understand the meaning of to rig a sling for someone
The situation is as follows:

[Mister Micawber]

.
1-- Take a large square of cloth; fold it diagonally, so that it is now triangular in shape; place the widest portion beneath the injured arm; tie the two narrow corners around the victim's neck, so that the arm is supported horizontally in front of the body.

2-- You have 'it'll keep' correctly defined.
