-When a Docker container is created with `docker create`, it can be started using `docker start` multiple times (you can also use the `docker run` command to create and start a container simultaneously). The container may run and finish immediately or run for an extended duration, depending on the processes it executes.

-A [[Docker]] container is a process or a set of processes with isolated resources that are logically (not physically) allocated from the hard drive by the kernel using `namespacing` and `cgroups`. 
+A [[Docker]] container is a process or a set of processes with isolated resources that are logically (not physically) allocated from the hard drive by the kernel using `namespacing` and `cgroups`. Each container has its own lifecycle, see [[Docker Container Lifecycle]] for more information.
 
 - `namespacing` is an OS feature that segments hardware resources for specific processes. For example, creating separate segments on the hard drive for Python 2 and Python 3, and directing system calls to the appropriate segment based on which application is making the call.
 - `cgroups` (Control Groups) limit the amount of resources (CPU, memory, network bandwidth) a process can use.

+
+## docker create
+
+The `docker create` command takes an [[docker image|image]] and creates a new [[docker container|container]] without running it. It then prints the `container_id` for further operations. You can specify a **startup command** for this container at the time of creation, which will be executed each time the container is started.
+
+```bash
+docker create [options] image_name [command]
+```
+
+>[!example]
+> The following example creates a new container from the `busybox` image and assigns a startup command of `echo hello`.

+>docker create busybox echo hello
+># 610ea68044541a3b4e2bac5ca889b6978e1fa529dd5c96199aeeb11b9b9b5765
+>```
+
+## docker start
+
+The `docker start` simply starts the [[docker container|container]] we created with `docker create`, or restarts the [[docker container|container]] that was already finished and stopped.
+
+```
+docker start [options] container_id
+```
+
+>[!example]
+>The following example starts the `busybox` container with the command `echo hello`. We also append an `-a` flag to display the output of the container. 
+>```bash
+>docker start -a 610ea68044541a3b4e2bac5ca889b6978e1fa529dd5c96199aeeb11b9b9b5765
