 This is the backend part of the `code-coverage` plugin. It takes care of processing various coverage formats and standardizing them into a single json format, used by the frontend.

+## Installation
+
+`yarn workspace backend add @backstage/plugin-code-coverage-backend`
+
+First create a `codecoverage.ts` file here: `packages/backend/src/plugins`. Now add the following as its content:
+
+```diff
+diff --git a/packages/backend/src/plugins/codecoverage.ts b/packages/backend/src/plugins/codecoverage.ts
+--- /dev/null
+++ b/packages/backend/src/plugins/codecoverage.ts
+@@ -0,0 +1,15 @@
+import { createRouter } from '@backstage/plugin-code-coverage-backend';
+import { Router } from 'express';
+import { PluginEnvironment } from '../types';
+
+export default async function createPlugin(
+  env: PluginEnvironment,
+): Promise<Router> {
+  return await createRouter({
+    config: env.config,
+    discovery: env.discovery,
+    database: env.database,
+    urlReader: env.reader,
+    logger: env.logger,
+  });
+}
+
+```
+
+Finally we need to load the plugin in `packages/backend/src/index.ts`, make the following edits:
+
+```diff
