 ```bash
-dgraph acl -d localhost:9180 mod -u groot

 Now type in the password for the groot account, which is the superuser that has access to everything. The default password is `password`.

 5. Assign predicate permissions to the group
 ```bash
-dgraph acl mod -d localhost:9180 -g dev -p friend -P 7
+dgraph acl mod -d localhost:9180 -g dev -p friend -m 7
 ```
 The command above grants the `dev` group the `READ`+`WRITE`+`MODIFY` permission on the `friend` predicate. Permissions are represented by a number following the UNIX file permission convention.
 That is, 4 (binary 100) represents `READ`, 2 (binary 010) represents `WRITE`, and 1 (binary 001) represents `MODIFY` (the permission to change a predicate's schema). Similarly, permisson numbers can be bitwise OR-ed to represent multiple permissions. For example, 7 (binary 111) represents all of `READ`, `WRITE` and `MODIFY`.
 In order for the example in the next section to work, we also need to grant full permissions on another predicate `name` to the group `dev`
 ```bash
-dgraph acl mod -d localhost:9180 -g dev -p name -P 7
+dgraph acl mod -d localhost:9180 -g dev -p name -m 7

 ### Access data using a client
 
 Now that the ACL data are set, to access the data protected by ACL rules, we need to first log in through a user.
-In the dgo client, this is done through the `Login` method:
-```go
-	serviceAddr := "localhost:9180"
-	conn, err := grpc.Dial(serviceAddr, grpc.WithInsecure())
-	if err != nil {
-		return err
-	}

-	ctx := context.Background()

-	}
-
-	txn := dg.NewTxn()
-	defer txn.Discard(ctx)
-	_, err = txn.Mutate(...)
