+## Developer Certificate of Origin
+
+OpenSearch is an open source product released under the Apache 2.0 license (see either [the Apache site](https://www.apache.org/licenses/LICENSE-2.0) or the [LICENSE.txt file](LICENSE.txt)). The Apache 2.0 license allows you to freely use, modify, distribute, and sell your own products that include Apache 2.0 licensed software.
+
+We respect intellectual property rights of others and we want to make sure all incoming contributions are correctly attributed and licensed. A Developer Certificate of Origin (DCO) is a lightweight mechanism to do that.
+
+The DCO is a declaration attached to every contribution made by every developer. In the commit message of the contribution, the developer simply adds a `Signed-off-by` statement and thereby agrees to the DCO, which you can find below or at [DeveloperCertificate.org](http://developercertificate.org/).
+
+```
+Developer's Certificate of Origin 1.1
+
+By making a contribution to this project, I certify that:
+
+(a) The contribution was created in whole or in part by me and I
+    have the right to submit it under the open source license
+    indicated in the file; or
+
+(b) The contribution is based upon previous work that, to the
+    best of my knowledge, is covered under an appropriate open
+    source license and I have the right under that license to
+    submit that work with modifications, whether created in whole
+    or in part by me, under the same open source license (unless
+    I am permitted to submit under a different license), as
+    Indicated in the file; or
+
+(c) The contribution was provided directly to me by some other
+    person who certified (a), (b) or (c) and I have not modified
+    it.
+
+(d) I understand and agree that this project and the contribution
+    are public and that a record of the contribution (including
+    all personal information I submit with it, including my
+    sign-off) is maintained indefinitely and may be redistributed
+    consistent with this project or the open source license(s)
+    involved.
+ ```
+
+We require that every contribution to OpenSearch is signed with a Developer Certificate of Origin. Additionally, please use your real name. We do not accept anonymous contributors nor those utilizing pseudonyms.
+
+Each commit must include a DCO which looks like this
+
+```
+Signed-off-by: Jane Smith <jane.smith@email.com>
+```
+
+You may type this line on your own when writing your commit messages. However, if your user.name and user.email are set in your git configs, you can use `-s` or `--signoff` to add the `Signed-off-by` line to the end of the commit message.
+
+## License Headers
+New files in your code contributions should contain the following license header. If you are modifying existing files with license headers, or including new files that already have license headers, do not remove or modify them without guidance.
+
+### Typescript/Javascript
+```

 ## Finding contributions to work on
 Looking at the existing issues is a great way to find something to contribute on. As our projects, by default, use the default GitHub issue labels (enhancement/bug/duplicate/help wanted/invalid/question/wontfix), looking at any 'help wanted' issues is a great place to start.

+# Developer Guide
+
+## Prerequisites
+
+To work on OpenSearch-Dashboards(OSD) plugins, you must have OpenSearch and OpenSearch-Dashboards running.
+
+1. Follow this [link](https://opensearch.org/docs/latest/install-and-configure/install-opensearch/index/) to setup OpenSearch, you can easily get OpenSearch up and running [with Docker](https://opensearch.org/docs/latest/install-and-configure/install-opensearch/docker/)
+2. You also need to run OSD dev server, check this [link](https://github.com/opensearch-project/OpenSearch-Dashboards/blob/main/DEVELOPER_GUIDE.md) to setup local development environment
+
+## Setup
+
+1. Fork this repository
+2. Change working directory to OSD `/plugins` folder: `cd OpenSearch-Dashboards/plugins`
+3. Clone this repo to plugins folder, `git clone git@github.com:<your-github-username>/ml-commons-dashboards.git ./`
+
+## Install and Run
+
+```bash
+# install dependencies in OpenSearch-Dashboards/plugins/ml-commons-dashboards
+cd ml-commons-dashboards
+yarn osd bootstrap
+
+# Go to OSD project root and run bootstrap to make sure all deps are installed
+yarn osd bootstrap
+
+# start OSD dev server
+yarn start
+```
+
+If everything went well, OSD will be available on `http://localhost:5601/`
+
+## Unit Test
+
+In `plugins/ml-commons-dashboards` folder
+
+```bash
+# run tests
+yarn test:jest
+
+# or in watch mode
+yarn test:jest --watch
+```
+
+NOTE: Before creating a pull request, please make sure all tests are passed. You’re also encouraged to write tests to cover the code changes you made.
