+# Docker Development Environment Setup
+The following instructions demonstrate how to set up a development environment for OpenSearch Dashboards using Docker. It utilizes tools such as `Docker` and `VS Code`, and users should be familiar with the basic usages of them. Users will be able to develop and run the application inside VS Code without additional configurations.
+
+1. Install [Docker](https://docs.docker.com/get-docker/) if not already installed. 
+    * Make sure that Docker daemon is running. (For windows and macos，you need to have [Docker Desktop](https://docs.docker.com/desktop/), or its alternatives, such as [Finch](https://github.com/runfinch/finch))
+
+2. In the terminal, run the command below.
+    * This should create a folder named `opensearch-dashboards-docker-dev` and it should contain two files: `docker-compose.yml` and `entrypoint.sh`. 
+    * Here is the link to the installer script: `https://raw.githubusercontent.com/opensearch-project/OpenSearch-Dashboards/main/dev-tools/install-docker-dev.sh` if needed.
+
+```bash
+curl -o- https://raw.githubusercontent.com/opensearch-project/OpenSearch-Dashboards/main/dev-tools/install-docker-dev.sh | bash
+```
+
+3. Open VS Code or [install it](https://code.visualstudio.com/download), if it's not already installed. 
+    * Make sure VS Code has the extensions `Dev Containers` and `Docker` installed. If not, go to `Extensions` tab, search and install them.
+
+4. Under the Discover tab, click `Open Folder`, and open the `opensearch-dashboards-docker-dev` folder that we just created.
+
+5. Open the `opensearch-dashboards-docker-dev` folder in VS Code integrated terminal, set environment variable for the fork repository URL by running the command below.
+    * If fork repo has not been created: Go to [OpenSearch Dashboards github page](https://github.com/opensearch-project/OpenSearch-Dashboards) and under fork, select create a new fork, and then copy the https link of the fork url and use it in the above command. The command needs to be re-run every time it re-start the docker compose file in a new terminal.
+```bash
+export REPO_URL=[insert your fork repo url here]
+``` 
+
+6. Run the `docker-compose.yml` file in the background by typing: 
+```bash
+docker compose up -d --build
+```
+
+7. Under the `Docker` tab in VS Code, verify that there are two containers running: `opensearchproject/opensearch:latest` and `abbyhu/opensearch-dashboards-dev:latest`. 
+    * This can also be verified by using the command line: 
+    ```bash
+    docker ps
+    ```
+
+8. Right-click `abbyhu/opensearch-dashboards-dev:latest`, and select `Attach Visual Studio Code`. 
+    * This will ssh into the container and you will be able to view and edit the files using VS Code as the code editor. 
+    * If you do not wish to use VS Code as the code editor, the alternative way of ssh into the container is by using the command below: 
+    ```bash
+    docker exec -it dev-env /bin/bash
+    ```
+
+9. For the new VS Code window, if it is not showing the repository code, then select `Open Folder`. Then open `/workspace-docker/OpenSearch-Dashboards`.
+
+10. In the terminal, start the OpenSearch Dashboards application by typing:
+```bash
+yarn start:docker
+```
+
+11. Now that OpenSearch Dashboards is running, you should be able to see a log line similar to `[info][server][OpenSearchDashboards][http] http server running at http://0.0.0.0:5603/dog`. 
+    * The last three letters `dog` are randomly generated every time we start dashboards.
+
+12. Wait for the optimizer to run, which takes about 100s - 200s. Once the optimizer is finished running, it will show a line such as `[success][@osd/optimizer] 48 bundles compiled successfully after 204.9 sec, watching for changes`.
+
+13. Then paste the link into a chrome browser and view dashboard running in browser, but change ‘0.0.0.0’ to ‘localhost’. So here the link should be `http://localhost:5603/dog`.
+    * Files are constantly watched, so when you make code changes, OpenSearch Dashboards will rebuild and restart automatically. Refresh the link in the browser and the new changes should be applied.
+
+14. `Git` is already configured in the `entrypoint.sh` file, and the remote is already tracking the fork repository. You can start contributing by creating your branch off the main, and commit your first PR!
