 1. The Container Lifecycle

+Created ---> Running ---> Stopped
+   ^          |  ^          |
+   |          |  |          |

+
+States and Transitions
+
+1. **Created**
+   - Initial state after `docker create`
+   - Can transition to:
+     - Running (via `docker start`)
+     - Removed (via `docker rm`)
+
+2. **Running**
+   - Container is executing
+   - Reached via `docker start` from Created or Stopped state
+   - Can transition to:
+     - Stopped (via `docker stop` or when process completes)
+     - Paused (via `docker pause`)
+
+3. **Stopped**
+   - Container has been stopped
+   - Can transition to:
+     - Running (via `docker start`)
+     - Removed (via `docker rm`)
+
+4. **Paused**
+   - Container execution is paused
+   - Can transition to:
+     - Running (via `docker unpause`)
+
+5. **Removed**
+   - Container is deleted
+   - Final state, reached via `docker rm` from Created or Stopped state
+
+Key Docker Commands
+
+- `docker create`: Create a new container (Created state)
+- `docker start`: Start a container (transition to Running)
+- `docker stop`: Stop a running container (transition to Stopped)
+- `docker pause`: Pause a running container (transition to Paused)
+- `docker unpause`: Unpause a paused container (return to Running)
+- `docker rm`: Remove a stopped or created container (transition to Removed)
