Warehouse management - where to find how to use erpnext to manage inventorylevels and locals

I am trying to find more information on the warehouse management functions of erpnext

I plan on moving from 3rd party logistics to my own warehouse in the next couple of years.

I have read that erpnext does offer this as a function, but I do not know how it works and where to find it.

Can some one point me in the right place to learn about it?

Thanks

Joseph

A good place to start is the official documentation.
