How to add RayMarching to Unity 2019.3 HDRP with Volumes?

I don’t know how to do it. HELP!

What have you tried so far? You would most likely implement raymarching as a post-processing effect. But there are other ways of doing it, too.

Ye-a. I tried a ready-made Ray-Marching code for post-processing. I am not strong in him. But the new Unity uses Volumes/

I have code and shader with raymarching of volumetric clouds that work in standart render of Unity, but i can’t use it for HDRP/

can you share some code that help me with this problem, 'cause i can’t find information about raymarching in HDRP/

You wrote that there are several ways to do this. Can you write what are these ways?
