>>2714555Attend a mountaineering course and read the book "Mountaineering: the freedom of the hills"
Acquire basic gear like mountaineering boots (important for stability, warmth and crampon compatibility) crampons (at least semi automatic/hybrid crampon with a rear lever, require a heel welt on boots), an ice ax (long and straight, for walking, not the short and curved ones for ice climbing) and a helmet.
Learn how to self arrest and self belay using the ice ax. Practice a lot to get it into muscle memory.
Don't fall. Don't fall for summit fever either. It's better to turn around and live, than to summit and die. A quote from mountaineer Ed Viesturs comes to mind: "Getting to the summit is optional, getting down is mandatory".
And lastly, respect the mountain.
