When new users run docker run … in the tutorial and Docker Desktop isn’t running, they just get cryptic errors.

[Rahilralu]

Add a small script (in Bash for Linux/macOS and PowerShell for Windows) that:

Checks if Docker is running

Prints a friendly message if it’s not

Suggests how to start it

Example (Bash):

bash
Copy
Edit
#!/bin/bash
if ! docker info > /dev/null 2>&1; then
echo "❌ Docker is not running."
echo "Please start Docker Desktop and try again."
exit 1
fi
echo "✅ Docker is running fine!"
This could live in a scripts/ folder and be mentioned in the tutorial.
