1) coasting in neutral / foot not on clutch;

2a) push clutch all the way in;
b) let the clutch out part way (to spin up the motor);
c) then press it back down;

3) shift into the appropriate gear;

4) touch the throttle to bring up the engine speed / to match the transmission speed

5) then release the clutch.

I presume that re-engage in #5 of instructions means release.

Is this all correct?
Not quite. Here is how to bump start

While coasting with engine off and in neutral

1) clutch in
2) select 2 gears higher than you would normally be at any given speed
3) let off the clutch slowly until the engine fires on
4) then immediately step on the clutch again (this is to prevent the car from jerking)
5) select your normal gear at any given speed
6) blip the throttle to rev match
7) release clutch, then if you rev matched properly, the car should not jerk
8) continue driving
