+Besides the broker protocol it also provides REST endpoints for handling schedules, jobs, calls and histories (basic CRUD operations), these endpoints are called by the [scheduler-plugin](https://github.com/rabobank/scheduler-plugin/).  
 In the background it also runs a routine that checks the existing schedules to see if it needs to run cf tasks, or needs to call URLs.
 
 ### Deploying/installing the broker
 
-## Prepare the database
+## Prepare the database on the CF deployment
 
+In most cases you will use the cf mysql database for the broker.  
 Do a bosh login into one of the cf database servers (_bosh -d cf ssh database/0_), and switch to root.
 Do a _mysql -u scheduler -p -h 127.0.0.1 --database=scheduler_, you will be prompted for the password, get this from credhub entry **/bosh/cf/scheduler_database_password**
+By setting the SSB_DB_HOST to another host, you can use another database server, outside CF.
 
 # Update cf-deployment
 We recommend using the cf mysql database.
