 ## How to index TechDocs documents

 1. Import the `DefaultTechDocsCollatorFactory` from

+   ```typescript
+   import { DefaultTechDocsCollatorFactory } from '@backstage/plugin-techdocs-backend';

 2. If there isn't an existing schedule you'd like to run the collator on, be
    sure to create it first. Something like...
 
-    ```typescript
-    import { Duration } from 'luxon';
+   ```typescript
+   import { Duration } from 'luxon';
 
-    const every10MinutesSchedule = env.scheduler.createScheduledTaskRunner({

+     timeout: Duration.fromObject({ seconds: 900 }),
+     initialDelay: Duration.fromObject({ seconds: 3 }),
+   });
+   ```
 
 3. Register the `DefaultTechDocsCollatorFactory` with the IndexBuilder.
 
-    ```typescript
-    indexBuilder.addCollator({
-      schedule: every10MinutesSchedule,
-      factory: DefaultTechDocsCollatorFactory.fromConfig(env.config, {
-        discovery: env.discovery,

+   indexBuilder.addCollator({

 choice!
