# Docker Usage Guide
## Starting Docker in Container Environments
Please check if docker is already installed. If so, to start Docker in a container environment:
```bash
# Start Docker daemon in the background
sudo dockerd > /tmp/docker.log 2>&1 &
# Wait for Docker to initialize
sleep 5
```
## Verifying Docker Installation
To verify Docker is working correctly, run the hello-world container:
```bash
sudo docker run hello-world
```
