-3. At this point you are in the docker environment and can run the qlib scripts. An example:
-    ```bash
-    >>> python scripts/get_data.py qlib_data --name qlib_data_simple --target_dir ~/.qlib/qlib_data/cn_data --interval 1d --region cn
-    >>> python qlib/workflow/cli.py examples/benchmarks/LightGBM/workflow_config_lightgbm_Alpha158.yaml
-    ```
-4. Exit the container
-    ```bash
-    >>> exit
-    ```
-5. Restart the container
-    ```bash
-    docker start -i -a <container name>
-    ```
-6. Stop the container
-    ```bash
-    docker stop <container name>
-    ```
-7. Delete the container

-
-==================
-Build Docker Image
-==================
-
-Dockerfile
-==========
-
-There is a **Dockerfile** file in the root directory of the project from which you can build the docker image. There are two build methods in Dockerfile to choose from.
-When executing the build command, use the ``--build-arg`` parameter to control the image version. The ``--build-arg`` parameter defaults to ``yes``, which builds the ``stable`` version of the qlib image.
-
-1.For the ``stable`` version, use ``pip install pyqlib`` to build the qlib image.
-
-.. code-block:: bash
-
-    docker build --build-arg IS_STABLE=yes -t <image name> -f ./Dockerfile .
-
-.. code-block:: bash
-
-    docker build -t <image name> -f ./Dockerfile .
-
-2. For the ``nightly`` version, use current source code to build the qlib image.
-
-.. code-block:: bash
-
-    docker build --build-arg IS_STABLE=no -t <image name> -f ./Dockerfile .
-
-Auto build of qlib images
-=========================
-
-1. There is a **build_docker_image.sh** file in the root directory of your project, which can be used to automatically build docker images and upload them to your docker hub repository(Optional, configuration required).
-
-.. code-block:: bash
-
-    sh build_docker_image.sh
-    >>> Do you want to build the nightly version of the qlib image? (default is stable) (yes/no):
-    >>> Is it uploaded to docker hub? (default is no) (yes/no):
-
-2. If you want to upload the built image to your docker hub repository, you need to edit your **build_docker_image.sh** file first, fill in ``docker_user`` in the file, and then execute this file.
-
-How to use qlib images
-======================
-1. Start a new Docker container
-
-.. code-block:: bash
-
-    docker run -it --name <container name> -v <Mounted local directory>:/app <image name>
-
-2. At this point you are in the docker environment and can run the qlib scripts. An example:
-
-.. code-block:: bash
-
-    >>> python scripts/get_data.py qlib_data --name qlib_data_simple --target_dir ~/.qlib/qlib_data/cn_data --interval 1d --region cn
-    >>> python qlib/workflow/cli.py examples/benchmarks/LightGBM/workflow_config_lightgbm_Alpha158.yaml
-
-3. Exit the container
-
-.. code-block:: bash
-
-    >>> exit
-
-4. Restart the container
-
-.. code-block:: bash
-
-    docker start -i -a <container name>
-
-5. Stop the container
-
-.. code-block:: bash
-
-    docker stop -i -a <container name>
-
-6. Delete the container
-
-.. code-block:: bash
-
-    docker rm <container name>
-
-7. For more information on using docker see the `docker documentation <https://docs.docker.com/reference/cli/docker/>`_.

-# Introduction
-
-What is GeneralPtNN
-- Fix previous design that fail to support both Time-series and tabular data
-- Now you can just replace the Pytorch model structure to run a NN model.
-
-We provide an example to demonstrate the effectiveness of the current design.
-- `workflow_config_gru.yaml` align with previous results [GRU(Kyunghyun Cho, et al.)](../README.md#Alpha158-dataset)
-  - `workflow_config_gru2mlp.yaml` to demonstrate we can convert config from time-series to tabular data with minimal changes
-    - You only have to change the net & dataset class to make the conversion.
-- `workflow_config_mlp.yaml` achieved similar functionality with [MLP](../README.md#Alpha158-dataset)
-
-# TODO
-
-- We will align existing models to current design.
-
-- The result of `workflow_config_mlp.yaml` is different with the result of [MLP](../README.md#Alpha158-dataset) since GeneralPtNN has a different stopping method compared to previous implementations. Specificly, GeneralPtNN controls training according to epoches, whereas previous methods controlled by max_steps.
