Is Node and Yarn needed to install Encore?

[PhoneixS]

In the guide Install Encore apperars the next text:

First, make sure you install Node.js_ and also the Yarn package manager_.
The following instructions depend on whether you are installing Encore in a
Symfony application or not.

With and also it appears to me that you need to install both but I think that you can install Encore with only npm.

Is it correct that you could install it with only npm or do you need to install both?

If you only need one, I think the documentation should be changed to reflect that. Else, I think it should be explained as new users (as me) could be confused by the fact that said and but then in the examples said if you use X do Y.

You are right. We're improving this in #16123. Thanks!
