Here is a step-by-step guide to deploy a Docker Nginx "Hello World" app:

Install Docker on your machine. You can find the installation instructions for your operating system at the official Docker website.
Create a new directory for your app and navigate to it in your terminal.
Create a new file named "Dockerfile" in this directory and paste the following content:

FROM nginx:alpine
COPY index.html /usr/share/nginx/html/

<!DOCTYPE html>
<html>
  <head>
    <title>Hello World</title>
  </head>
  <body>
    <h1>Hello World</h1>
  </body>
</html>

docker build -t hello-world-nginx .

Run the following command to start a new container based on the image you just built:

docker run -p 8080:80 hello-world-nginx

Visit http://localhost:8080 in your browser to see the "Hello World" message displayed by Nginx.

That's it! You have successfully deployed a Docker Nginx "Hello World" app.
