Warning

Firewall rules blocked me from connecting to one or more addresses

I tried to connect to the following addresses, but was blocked by firewall rules:

• api.openweathermap.org
  • Triggering command: /usr/local/bin/node /home/REDACTED/work/weather-app/weather-app/node_modules/react-scripts/scripts/test.js --passWithNoTests --watchAll=false (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to my firewall allow list

This pull request was created as a result of the following prompt from Copilot chat.

Replace the existing README.md with a new, comprehensive documentation specific to this Simple Weather App project. The new README should include:

1. Project Overview: Brief description of the app and its purpose.
2. Features: List of main features (search by city, display weather details, responsive design, etc.).
3. Installation: Steps to clone and run the app locally.
4. Usage: Instructions for using the app.
5. API Configuration: How to set up the weather API key in the JavaScript file.
6. Project Structure: Overview of key files (index.html, style.css, script.js).
7. Contributing: Guidelines for contributing.
8. License: Specify MIT license.

Remove all Create React App default content. The README should be clear, concise, and informative for users and contributors.
