+# OpenSearch Dashboards Plugin Generator
+
+This package can be used to generate a OpenSearch Dashboards plugin from the OpenSearch Dashboards repo.
+
+## Setup
+
+Before you can use this plugin generator you must setup your [OpenSearch Dashboards development environment](../../CONTRIBUTING.md#development-environment-setup). If you can successfully run `yarn osd bootstrap` then you are ready to generate plugins!
+
+## Compatibility
+
+The plugin generator became a part of the OpenSearch Dashboards project as of OpenSearch Dashboards 6.3. If you are targeting versions **before OpenSearch Dashboards 6.3** then use the [Kibana plugin sao template](https://github.com/elastic/template-kibana-plugin).
+
+If you are targeting **OpenSearch Dashboards 6.3 or greater** then checkout the corresponding OpenSearch Dashboards branch and run the plugin generator.
+
+## Quick Start
+
+To target the current development version of OpenSearch Dashboards just use the default  `master` branch.
+
+```sh
+node scripts/generate_plugin --name my_plugin_name -y
+# generates a plugin in `plugins/my_plugin_name`
+```
+
+To target 6.8, use the `6.8` branch.
+
+```sh
+git checkout 6.x
+yarn osd bootstrap # always bootstrap when switching branches
+node scripts/generate_plugin --name my_plugin_name -y
+# generates a plugin for OpenSearch Dashboards 6.8 in `../opensearch-dashboards-extra/my_plugin_name`
+```
+
+The generate script supports a few flags; run it with the `--help` flag to learn more.
+
+```sh
+node scripts/generate_plugin --help
+```
+
+## Updating
+
+Since the Plugin Generator is now a part of the OpenSearch Dashboards repo, when you update your local checkout of the OpenSearch Dashboards repository and `bootstrap` everything should be up to date!
+
+> ***NOTE:*** These commands should be run from the OpenSearch Dashboards repo, and `upstream` is our convention for the git remote that references https://github.com/elastic/kibana.git, unless you added this remote you might need to use `origin`.
+
+```sh
+git pull upstream master
+yarn osd bootstrap
+```
+
+## Plugin Development Scripts
+
+Generated plugins receive a handful of scripts that can be used during development. Those scripts are detailed in the [README.md](template/README.md) file in each newly generated plugin, and expose the scripts provided by the [OpenSearch Dashboards plugin helpers](../osd-plugin-helpers), but here is a quick reference in case you need it:
+
+> ***NOTE:*** All of these scripts should be run from the generated plugin.
+
+  - `yarn osd bootstrap`
+
+    Install dependencies and crosslink OpenSearch Dashboards and all projects/plugins.
+
+    > ***IMPORTANT:*** Use this script instead of `yarn` to install dependencies when switching branches, and re-run it whenever your dependencies change.
+
+  - `yarn start`
+
+    Start OpenSearch Dashboards and have it include this plugin. You can pass any arguments that you would normally send to `bin/opensearch-dashboards`
+
+      ```
+      yarn start --opensearch.hosts http://localhost:9220
+      ```
+
+  - `yarn build`
+
+    Build a distributable archive of your plugin.
+
+  - `yarn test:mocha`
+
+    Run the server tests using mocha.
+
+For more information about any of these commands run `yarn ${task} --help`. For a full list of tasks run `yarn run` or take a look in the `package.json` file.
