+# Run OpenSearch Dashboards using the development server
+
+If you want to develop on OpenSearch Dashboards or maybe create plugins for it,
+you need to run it from source using the included development server.
+
+### Prerequisites
+
+You need to have an OpenSearch server up and running to be able to run OpenSearch
+Dashboards. The easiest way to do it is [using Docker]({{site.url}}{{site.baseurl}}/opensearch/install/docker).
+
+We recommend using [Node Version Manager](https://github.com/nvm-sh/nvm) to install
+the node version we need.
+
+## Bootstrap OpenSearch Dashboards
+
+While OpenSearch is starting, you can already bootstrap OpenSearch Dashboards:
+```bash
+$ git clone https://github.com/opensearch-project/OpenSearch-Dashboards.git
+$ cd OpenSearch-Dashboards
+$ nvm use
+$ yarn osd bootstrap # This command will also install npm dependencies
+```
+
+## Configure OpenSearch Dashboards
+
+*This step is only mandatory if you have https/authentication enabled, or if you use the OpenSearch Docker image in its default configuration.*
+
+Once the bootstrap of OpenSearch Dashboards is finished, you need to apply some
+changes to `opensearch_dashboards.yml` in order to connect to OpenSearch.
+
+```yml
+opensearch.hosts: ["https://localhost:9200"]
+opensearch.username: "admin" # Default OpenSearch username
+opensearch.password: "admin" # Default OpenSearch password
+opensearch.ssl.verificationMode: none
+```
+
+## Run OpenSearch Dashboards
+
+After you've installed OpenSearch Dashboards and configured it, you can start
+the development server:
+```bash
+$ yarn start
+```
+
+When the server is up and ready, click on the link displayed in your terminal to
+access it.
