Docker noob question

Hello, i am completely new to docker and ive been following this tutorial in hopes of getting better at it, but im stuck on step 6 Nana Janashia / techworld-js-docker-demo-app · GitLab

I have no idea where or what the app directory is. Can someone please help me? Merry Christmas

There are two preconditions for this step:

  1. Nodejs is installed on your local machine. If not: consult google how to install nodejs for your os.
  2. The git repo is cloned to your local machine.

Open a terminal, change to the app folder directory within the folder where you cloned the repository to, and then execute the commands.
