+# Community Plugin Submission
+
+Thanks for submitting your Nx Plugin to our community plugins list. Make sure to follow these steps to ensure that your PR is approved in a timely manner.
+
+## Plugin Requirements
+
+Before you submit your plugin to be listed in our registry, it needs to meet the following requirements:
+- Run some kind of automated e2e tests in your repository
+- Include `@nx/devkit` as a `dependency` in the plugin's `package.json`
+- List a `repository.url` in the plugin's `package.json`
+
+i.e.
+
+```
+{
+  "repository": {
+    "type": "git",
+    "url": "https://github.com/nrwl/nx.git",
+    "directory": "packages/web"
+  }
+}
+```
+
+Note: We reserve the right to remove unmaintained plugins from the registry.  If the plugins become maintained again, they can be resubmitted to the registry.
+
+## Steps to Submit Your Plugin
+- Use the following commit message template: `chore(core): nx plugin submission [PLUGIN_NAME]`
+- Update the `astro-docs/src/content/approved-community-plugins.json` file with a new entry for your plugin that includes `name`, `url`, `description`:
+
+Example:
+
+```json
+// astro-docs/src/content/approved-community-plugins.json
+
+[{
+    "name": "@community/plugin",
+    "url": "https://github.com/community/plugin",
+    "description": "This plugin provides the following capabilities."
+}]
+```
+
+Once merged, your plugin will be available when running the `nx list` command, and will also be available in the Plugin Registry on [nx.dev](https://nx.dev/docs/plugin-registry)
