Ledge Climbing mechanic

Hi, my name is Mark and I am a high school student currently working on Unity for a competition. My idea is a 2.5D platformer based on stealth. One mechanic I would love to add would be a mechanic where the character jumps to a ledge and grabs onto it and climbs to the next platform. The problem is, I don't have much experience with the engine and I don't know where to start. The animations are no problem, but I wouldn't know what to script for the character to complete the action. Is there anyone that can help with this problem or show me a video contributing to this issue?
Thank you for listening

 

in the nicest possible way... google.

"unity ledge grab site:forum.unity3d.com"

(towards the bottom of the first page that brings up there is even an "open source" pakour system to look at etc...)

 

Thanks, I really appreciate it.
