 Why do I need this?
--------------------------------------
+===================
+
+To make things simpler, and bring Composable Kernel and its dependencies together, 
+docker images can be found on `Docker Hub <https://hub.docker.com/r/rocm/composable_kernel/tags>`_. Docker images provide a complete image of the OS, the Composable Kernel library, and its dependencies in a single downloadable file. 
+
+Refer to `Docker Overview <https://docs.docker.com/get-started/overview/>`_ for more information on Docker images and containers.
+
+Which image is right for me?
+============================
+
+The image naming includes information related to the docker image. 
+For example ``ck_ub20.04_rocm6.0`` indicates the following:
+
+* ``ck`` - made for running Composable Kernel;
+* ``ub20.04`` - based on Ubuntu 20.04;
+* ``rocm6.0`` - ROCm platform version 6.0.
 
-To make our lives easier and bring Composable Kernel dependencies together, we recommend using
-docker images that can be found on `Docker Hub <https://hub.docker.com/r/rocm/composable_kernel>`_.
+Download a docker image suitable for your OS and ROCm release, run or start the docker container, and then resume the tutorial from this point. Use the ``docker pull`` command to download the file::

+=================================
 
-To run all the test cases including tests and examples run::
+After finishing the tutorial, or just when you have completed your work session, you can close the docker container, or stop the docker container to restart it at another time. Closing the docker container means that it is still in the active state, and can be resumed from where you left it. Stopping the container closes it, and returns the image to its initial state. 
 
-    make test
+Use the ``Ctrl-D`` option to exit the container, while leaving it active, so you can return to the container in its current state to resume the tutorial, or pickup your project where you left off. 
 
-We can also run specific examples or tests like::
+To restart the active container use the ``docker exec`` command to specify the container name and options as follows::
 
-    ./bin/example_gemm_xdl_fp16
-    ./bin/test_gemm_fp16
+    docker exec -it <container_name> bash
 
-For more details visit `CK github repository <https://github.com/ROCmSoftwarePlatform/composable_kernel>`_,

+Where: 
 
--------------------------------------
-And what is inside?
--------------------------------------
+* `exec` is the docker command
+* `-it` is the interactive option for `exec`
+* `<container_name>` specifies an active container on the system
+* `bash` specifies the command to run in the interactive shell
 
-The docker images have everything you need for running CK including:

-* `CMake <https://cmake.org/>`_
-* `Compiler <https://github.com/RadeonOpenCompute/llvm-project>`_
+    You can use the ``docker container ls`` command to list the active containers on the system.

-Which image is right for me?

-Let's take a look at the image naming, for example ``ck_ub20.04_rocm5.6``. The image specs are:
+To start a container from the image, use the ``docker start`` command::
 
-* ``ck`` - made for running Composable Kernel;
-* ``ub20.04`` - based on Ubuntu 20.04;
-* ``rocm5.6`` - ROCm platform version 5.6.

-So just pick the right image for your project dependencies and you're all set.
+Then use the docker exec command as shown above to start the bash shell.

+Use the ``docker stop`` command to stop the container and restore the image to its initial state::

+The Composable Kernel (CK) library provides a programming model for writing performance critical kernels for machine learning workloads across multiple architectures including GPUs and CPUs, through general purpose kernel languages like HIP C++. This document contains instructions for installing, using, and contributing to the Composable Kernel project. To learn more see :ref:`what-is-ck`.

-This tutorial is aimed at engineers dealing with artificial intelligence and machine learning who
-would like to optimize their pipelines and squeeze every performance drop by adding Composable
-Kernel (CK) library to their projects. We would like to make the CK library approachable so
-the tutorial is not based on the latest release and doesn't have all the bleeding edge features,

-During this tutorial we will have an introduction to the CK library, we will build it and run some
-examples and tests, so to say we will run a "Hello world" example. In future tutorials we will go

 Description

+===========
 
-Modern AI technology solves more and more problems in all imaginable fields, but crafting fast and
-efficient workflows is still challenging. CK is one of the tools to make AI heavy lifting as fast
-and efficient as possible. CK is a collection of optimized AI operator kernels and tools to create
-new ones. The library has components required for majority of modern neural networks architectures
-including matrix multiplication, convolution, contraction, reduction, attention modules, variety of
-activation functions, fused operators and many more.

 Build the library

+=================
 
-First let's clone the library and rebase to the tested version::
+This tutorial is based on the use of docker images as explained in :ref:`docker-hub`. Download a docker image suitable for your OS and ROCm release, run or start the docker container, and then resume the tutorial from this point. 
 
-    git clone https://github.com/ROCmSoftwarePlatform/composable_kernel.git
-    cd composable_kernel/
-    git checkout tutorial_hello_world
-
-To make our lives easier we prepared
-`docker images <https://hub.docker.com/r/rocm/composable_kernel>`_ with all the necessary
-dependencies. Pick the right image and create a container. In this tutorial we use
-``rocm/composable_kernel:ck_ub20.04_rocm5.6`` image, it is based on Ubuntu 20.04 and
-ROCm v5.6.
