+# @backstage/backend-common
+
+Common functionality library for Backstage backends, implementing logging,
+error handling and similar.
+
+## Usage
+
+Add the library to your backend package:
+
+```sh
+yarn add @backstage/backend-common
+```
+
+then make use of the handlers and logger as necessary:
+
+```typescript
+import {
+  logger,
+  errorHandler,
+  notFoundHandler,
+} from '@backstage/backend-common';
+
+const app = express();
+app.use('/home', myHomeRouter);
+app.use(errorHandler());
+app.use(notFoundHandler());
+
+app.listen(PORT, () => {
+  logger.info(`Listening on port ${PORT}`);
+});
+```
