Installing\updating composer

[amirHossein5]

I was following your instructions, but In my case the composer was not on the latest version(was 2.0), and I don't have permission to update that.

So when I was running composer, there were lots of warnings about deprecations, and worse than that it couldn't install the dependencies.

I've found this answer and worked for me.

So if you could add a new part for installing\updating composer.
