-Owned by: Platform
+The `@bitwarden/nx-plugin` library is a custom Nx plugin developed specifically for Bitwarden projects. It
+provides generators tailored to Bitwarden's architecture and coding standards.
 
-Custom Nx tools like generators and executors for Bitwarden projects
+## Overview
+
+This plugin extends Nx's capabilities with Bitwarden-specific **nx generators** that help maintain
+consistency across the codebase.
+
+### What are Nx Generators?
+
+Nx generators are code generation tools that follow templates to create or
+modify files in your project. They can:
+
+- Create new files from templates
+- Modify existing files
+- Update configuration files
+- Ensure consistent project structure
+- Automate repetitive tasks
+
+If you're familiar with the code generation tools of say, the angular CLI, then you can just think of =nx= generators as that but on a larger scale. Generators can be run using the Nx CLI with the `nx generate` command (or the shorthand `nx g`).
+
+### When to Use Generators
+
+Use generators when:
+
+- Creating new libraries, components, or features that follow a standard pattern
+- You want to ensure consistency across similar parts of your application
+- You need to automate repetitive setup tasks
+- You want to reduce the chance of human error in project setup
+
+## How `@bitwarden/nx-plugin` Fits Into the Project Architecture
+
+`@bitwarden/nx-plugin` is designed to:
+
+1. Enforce Bitwarden's architectural decisions and code organization
+2. Streamline the creation of new libraries and components
+3. Ensure consistent configuration across the project
+4. Automate updates to project metadata and configuration files
+5. Reduce the learning curve for new contributors
+
+By using this plugin, we maintain a consistent approach to code organization and structure across
+the entire project.
+
+## Installation and Setup
+
+The plugin is included as a development dependency in the project. If you're working with a fresh
+clone of the repository, it will be installed when you run:
+
+```bash
+npm install
+```
+
+No additional setup is required to use the generators provided by the plugin.
+
+## Available Generators
+
+The plugin currently includes the following generators:
+
+- `basic-lib`: Creates a new library with standard configuration and structure. Specific documentation for the `basic-lib` generator can be found [here](./docs/using-the-basic-lib-generator.md)
+
+Additional generators may be added in the future to support other common patterns in the Bitwarden
+codebase.
+
+## Creating A Nx Generator
+
+This library is maintained by platform, but anyone from any team can add a
+generator if there is any amount of value added. If you need to create a new
+generator please do so by running
+
+```bash
+npx nx generate @nx/plugin:generator libs/nx-plugin/src/generators/your-generator-name-here}
+```
+
+This will create a basic generator structure for you to get started with.
