Need help installing and configuring

I don’t know programming, can someone help me install and configure
I don’t even know where to start. A bit of jab in JSON and using Zapeir. Will there be enough such knowledge to use this product on my own?
What do you need to install the program? What are the basic settings and where to do it? I read the documentation, but did not understand where to start.
Please, help

First welcome to the community!
That depends on where you want to install it exactly (on your computer for testing or a server).
If you want to install it just to play around a little bit and test it. You would have to first install either Node.js or Docker (recommended). How that is done depends on your operating system. So if you google “how to install docker on X” you should find some tutorials on how to do that. Once that is done you can simply follow the instructions here:
So in the simplest way you can start n8n with this command this:

docker run -it --rm \
  --name n8n \
  -p 5678:5678 \
  -v ~/.n8n:/root/.n8n \
  n8nio/n8n \
  n8n start --tunnel

On the other hand, if you want to install it on a server to run it long term “properly” it is best to get a server which runs on Ubuntu and then simply follow the step by step guide here:

I hope that helps!
