 ## Configure Dag Controller
 
-Dag Controller is a task scheduling tool that can schedule the jobs which type is DAG (directed acyclic graph). The job consists of multiple tasks to form a directed acyclic graph, and there is a dependency between the tasks.
+Dag Controller is a task scheduling tool that can schedule the jobs whose type is DAG (directed acyclic graph). The job consists of multiple tasks to form a directed acyclic graph, and there is a dependency between the tasks.
 
 The Dag Controller can perform complex graph computing with NebulaGraph Analytics. For example, the Dag Controller sends an algorithm request to NebulaGraph Analytics, which saves the result to NebulaGraph or HDFS. The Dag Controller then takes the result as input to the next algorithmic task to create a new task.
 
 ### Steps
 
 1. Complete the SSH password-free configurations so that the Dag Controller machine can log directly into the NebulaGraph Analytics machines and all machines within the NebulaGraph Analytics cluster can connect directly to each other without passwords.
 
-  For example, the user in the machine A (Dag Controller) log directly into machine B-1 in the NebulaGraph Analytics cluster over SSH  without passwords. Run the following commands on the machine A:
