-Welcome to the todo backend plugin!
+Backend for the `@backstage/plugin-todo` plugin. Assists in scanning for and listing `// TODO` comments in source code repositories.
 
-_This plugin was created through the Backstage CLI_
+## Installation
 
-## Getting started
+Install the `@backstage/plugin-todo-backend` package in your backend packages, and then integrate the plugin using the following default setup for `src/plugins/todo.ts`:
 
-Your plugin has been added to the example app in this repository, meaning you'll be able to access it by running `yarn start` in the root directory, and then navigating to [/todo](http://localhost:3000/todo).
+```ts
+import { Router } from 'express';
+import { CatalogClient } from '@backstage/catalog-client';
+import {
+  createRouter,
+  TodoReaderService,
+  TodoScmReader,
+} from '@backstage/plugin-todo-backend';
+import { PluginEnvironment } from '../types';
 
-You can also serve the plugin in isolation by running `yarn start` in the plugin directory.
-This method of serving the plugin provides quicker iteration speed and a faster startup and hot reloads.
-It is only meant for local development, and the setup for it can be found inside the [/dev](/dev) directory.
