Not sure that you want to 'learn the ropes' while high up in the mountain.
Probably better to find yourself a nice safe place to practise.
Take a look at videos like
And practise on safe ground. Appreciate its difficult with the patchy snow we get but i learn/practised ice axe arrest on llangynidr moors and traversing slopes/walking with crampons on the side of the A470 at storey arms. Just make sure theres a good concave run off with no rocks below. Youll be surprised how knackering it can be 1st time walking in snow.
Stiff boots are best way to go.
