 ```bash
 # format
-redis://x:<password>@<primary-region>.<appname>.internal:5432

 # example in scl
-redis://x:[email protected]:5432

 Read replicas are similar, but using a different region prefix (the `$FLY_REGION` environment variable is handy here).
 
 To generate a local read replica with Node.js, you might do something like:
 
 ```javascript
-const primary = new URL("redis://x:[email protected]:5432")
+const primary = new URL("redis://x:[email protected]:6379")
 const replica = new URL(primary)
 replica.hostname = `${process.env['FLY_REGION']}.my-redis-app.internal`
 replica.toString()
-// 'redis://x:[email protected]:5432'
-```
+// 'redis://x:[email protected]:6379'
