+
+## Contributor License Agreement
+
+It's required to sign CLA before your first code submission to MindSpore community.
+
+For individual contributor, please refer to [ICLA online document](https://www.mindspore.cn/icla) for the detailed information.
+
+## Getting Started
+
+- Fork the repository on [Github](https://github.com/mindspore-ai/mindspore) or [Gitee](https://gitee.com/mindspore/mindspore).
+- Read the [README.md](README.md) and [install page](https://www.mindspore.cn/install/en) for project information and build instructions.
+
+## Contribution Workflow
+
+### Code style
+
+Please follow this style to make MindSpore easy to review, maintain and develop.
+
+* Coding guidelines
+
+    The *Python* coding style suggested by [Python PEP 8 Coding Style](https://pep8.org/) and *C++* coding style suggested by [Google C++ Coding Guidelines](http://google.github.io/styleguide/cppguide.html) are used in MindSpore community.
+
+* Unittest guidelines
+
+    The *Python* unittest style suggested by [pytest](http://www.pytest.org/en/latest/) and *C++* unittest style suggested by [Googletest Primer](https://github.com/google/googletest/blob/master/googletest/docs/primer.md) are used in MindSpore community.
+
+### Fork-Pull development model
+
+* Fork MindSpore repository
+
+    Before submitting code to MindSpore project, please make sure that this project have been forked to your own repository. It means that there will be parallel development between MindSpore repository and your own repository, so be careful to avoid the inconsistency between them.
+
+* Clone the remote repository
+
+    If you want to download the code to the local machine, `git` is the best way:
+    ```shell
+    # For GitHub
+    git clone https://github.com/{insert_your_forked_repo}/mindspore.git
+    git remote add upstream https://github.com/mindspore-ai/mindspore.git
+    # For Gitee
+    git clone https://gitee.com/{insert_your_forked_repo}/mindspore.git
+    git remote add upstream https://gitee.com/mindspore/mindspore.git
+    ```
+
+* Develop code locally
+
+    To avoid inconsistency between multiple branches, checking out to a new branch is `SUGGESTED`:
+    ```shell
+    git checkout -b {new_branch_name} origin/master
+    ```
+
+    Then you can change the code arbitrarily.
+
+* Push the code to the remote repository
+
+    After updating the code, you should push the update in the formal way:
+    ```shell
+    git add .
+    git status # Check the update status
+    git commit -m "Your commit title"
+    git commit -s --amend #Add the concrete description of your commit
+    git push origin {new_branch_name}
+    ```
+
+* Pull a request to MindSpore repository
+
+    In the last step, your need to pull a compare request between your new branch and MindSpore `master` branch. After finishing the pull request, the Jekins CI will be automatically set up for building test.
+
+### Report issues
+
+A great way to contribute to the project is to send a detailed report when you encounter an issue. We always appreciate a well-written, thorough bug report, and will thank you for it!
+
+When reporting issues, refer to this format:
+
+- What version of env (mindspore, os, python etc) are you using?
+- Is this a BUG REPORT or FEATURE REQUEST?
+- What happened?
+- What you expected to happen?
+- How to reproduce it?(as minimally and precisely as possible)
+- Special notes for your reviewers?
+
+**Issues advisory:**
+
+- **If you find an unclosed issue, which is exactly what you are going to solve,** please put some comments on that issue to tell others you would be in charge of it.
+- **If an issue is opened for a while,** it's recommended for contributors to precheck before working on solving that issue.
+- **If you resolve an issue which is reported by yourself,** it's also required to let others know before closing that issue.
+
+### Propose PRs
+
+* Raise your idea as an *issue* on [GitHub](https://github.com/mindspore-ai/mindspore/issues) or [Gitee](https://gitee.com/mindspore/mindspore/issues)
+* If it is a new feature that needs lots of design details, a design proposal should also be submitted.
+* After reaching consensus in the issue discussions and design proposal reviews, complete the development on the forked repo and submit a PR.
+* None of PRs is not permitted until it receives **2+ LGTM** from approvers. Please NOTICE that approver is NOT allowed to add *LGTM* on his own PR.
+* After PR is sufficiently discussed, it will get merged, abondoned or rejected depending on the outcome of the discussion.
+
+**PRs advisory:**
+
+- Any irrelevant changes should be avoided.
+- Make sure your commit history being ordered.
+- Always keep your branch up with the master branch.
+- For bug-fix PRs, make sure all related issues being linked.

+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,

+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+

+## What Is MindSpore
+
+MindSpore is a new open source deep learning training/inference framework that
+could be used for mobile, edge and cloud scenarios. MindSpore is designed to
+provide development experience with friendly design and efficient execution for
+the data scientists and algorithmic engineers, native support for Ascend AI
+processor, and software hardware co-optimization. At the meantime MindSpore as
+a global AI open source community, aims to further advance the development and
+enrichment of the AI software/hardware application ecosystem.

+
+For more details please check out our [Architecture Guide](https://www.mindspore.cn/docs/en/0.1.0-alpha/architecture.html).
+
+### Automatic Differentiation
+
+There are currently three automatic differentiation techniques in mainstream deep learning frameworks:
+
+- **Conversion based on static compute graph**: Convert the network into a static data flow graph at compile time, then turn the chain rule into a data flow graph to implement automatic differentiation.
+- **Conversion based on dynamic compute graph**: Record the operation trajectory of the network during forward execution in an operator overloaded manner, then apply the chain rule to the dynamically generated data flow graph to implement automatic differentiation.
+- **Conversion based on source code**: This technology is evolving from the functional programming framework and performs automatic differential transformation on the intermediate expression (the expression form of the program during the compilation process) in the form of just-in-time compilation (JIT), supporting complex control flow scenarios, higher-order functions and closures.
+
+TensorFlow adopted static calculation diagrams in the early days, whereas PyTorch used dynamic calculation diagrams. Static maps can utilize static compilation technology to optimize network performance, however, building a network or debugging it is very complicated. The use of dynamic graphics is very convenient, but it is difficult to achieve extreme optimization in performance.
+
+But MindSpore finds another way, automatic differentiation based on source code conversion. On the one hand, it supports automatic differentiation of automatic control flow, so it is quite convenient to build models like PyTorch. On the other hand, MindSpore can perform static compilation optimization on neural networks to achieve great performance.
+
+<img src="docs/Automatic-differentiation.png" alt="Automatic Differentiation" width="600"/>
+
+The implementation of MindSpore automatic differentiation can be understood as the symbolic differentiation of the program itself. Because MindSpore IR is a functional intermediate expression, it has an intuitive correspondence with the composite function in basic algebra. The derivation formula of the composite function composed of arbitrary basic functions can be derived. Each primitive operation in MindSpore IR can correspond to the basic functions in basic algebra, which can build more complex flow control.
+
+### Automatic Parallel
+
+The goal of MindSpore automatic parallel is to build a training method that combines data parallelism, model parallelism, and hybrid parallelism. It can automatically select a least cost model splitting strategy to achieve automatic distributed parallel training.
+
+<img src="docs/Automatic-parallel.png" alt="Automatic Parallel" width="600"/>
+
+At present, MindSpore uses a fine-grained parallel strategy of splitting operators, that is, each operator in the figure is splited into a cluster to complete parallel operations. The splitting strategy during this period may be very complicated, but as a developer advocating Pythonic, you don't need to care about the underlying implementation, as long as the top-level API compute is efficient.
+

+# Security Risk Description
+
+1. When MindSpore is used for AI model training, if the user-defined computational graph structure (for example, Python code for generating the MindSpore computational graph) is provided by an untrusted third party, malicious code may exist and will be loaded and executed to attack the system.
+2. Model files are stored in binary mode. When MindSpore is used to optimize or infer AI models and the model files are loaded in deserialization mode, once malicious code is written into the model files, the code are loaded and executed, causing attacks on the system.
+3. MindSpore performs only model training and inference based on the data provided by users. Users need to protect data security to avoid privacy leakage.
+4. MindSpore is a distributed training platform. When MindSpore is used for distributed training, if an Ascend chip is used for training, a device provides a secure transmission protocol for gradient fusion. If GPUs or other clusters are used for training, identity authentication and secure transmission are not provided.
+
+# Security Usage Suggestions
+
+1. Run MindSpore in the sandbox.
+2. Run MindSpore as a non-root user.
+3. Ensure that the source of a computational graph structure is trustworthy. Do not write code irrelevant to model training in the network structure definition.
+4. Ensure that the source of a network model is trustworthy or enter secure network model parameters to prevent model parameters from being tampered with.
+5. Ensure that GPU distributed training is performed on an isolated cluster network.
