-## Set Up

-1. Install the plugin using:
-
-```bash
-# From your Backstage root directory
-yarn --cwd packages/backend add @backstage-community/plugin-nomad-backend
-```
-
-2. Create a `nomad.ts` file inside `packages/backend/src/plugins/`:
-
-```typescript
-import { createRouter } from '@backstage-community/plugin-nomad-backend';
-import { Router } from 'express';
-import { PluginEnvironment } from '../types';
-
-export default async function createPlugin(
-  props: PluginEnvironment,

-  return await createRouter(props);
-}

-3. Modify your `packages/backend/src/index.ts` to include:

-
- import { Config } from '@backstage/config';
- import app from './plugins/app';
-+import nomad from './plugins/nomad';

-   const authEnv = useHotMemoize(module, () => createEnv('auth'));

-   const apiRouter = Router();
-   apiRouter.use('/catalog', await catalog(catalogEnv));

 Note: for this backend to work, the `nomad` configuration described in the README of `@backstage-community/plugin-nomad` must be implemented.
