+# Plugins
+
+Nx plugins are npm packages that contain schematics and builders to extend a Nx workspace. Schematics are blueprints to create or modify code, and builders perform actions on the code.
+
+> A list of plugins maintained by Nrwl is found in the [Nrwl/nx repo](https://github.com/nrwl/nx/tree/master/packages). \
+> A list of custom plugins created by the community is found in the [Plugins](/nx-plugins) section.
+
+## nx list

+# Workspace Plugin
+
+The workspace plugin contains builders and schematics that are useful for any Nx workspace. It should be present in every Nx workspace and other plugins build on it.
+
+## Schematics
+
+- [library](/angular/plugins_workspace_schematics/library) - Create a plain typescript library
+- [move](/angular/plugins_workspace_schematics/move) - Move a project to another directory and update all references
+- [remove](/angular/plugins_workspace_schematics/remove) - Remove a project from the workspace
+- [workspace-schematic](/angular/plugins_workspace_schematics/workspace-schematic) - Scaffold a custom schematic for use within your workspace
+
+## Builders
+
+- [run-commands](/angular/plugins_workspace_builders/run-commands) - Execute an arbitrary command line script
