 NOTE: `--method graph` and `--num-group` are required to create groups.
 
-It is required to use the graph argument to generate groups through the graph partitioning.
-To generate groups using the Kernighan-Lin grouping algorithm use the flag `--method graph`
+It is required to use the graph argument to generate groups through the graph

 ```shell
-pipenv run python gatorgrouper_cli.py --file filepath --method graph --num-group NUMBER
+pipenv run python gatorgrouper_cli.py --file filepath --method graph
+--num-group NUMBER
 ```
 
 To load student preferences, a preference weight, use the flag `--preferences`
 
 ```shell
-pipenv run python gatorgrouper_cli.py --file filepath --method graph --num-group NUMBER
---preferences filepath
+pipenv run python gatorgrouper_cli.py --file filepath --method graph
+--num-group NUMBER --preferences filepath
 ```
 
 To indicate student preference weight use the flag `--preferences_weight`
 
 ```shell
-pipenv run python gatorgrouper_cli.py --file filepath --method graph --num-group NUMBER
---preferences filepath --preferences_weight PREFERENCES_WEIGHT
+pipenv run python gatorgrouper_cli.py --file filepath --method graph
+--num-group NUMBER --preferences filepath --preferences_weight PREFERENCES_WEIGHT
 ```
 
 To indicate preference weight match use the flag `--preferences_weight_match`
 
 ```shell
-pipenv run python gatorgrouper_cli.py --file filepath --method graph --num-group NUMBER
---preferences filepath --preferences_weight PREFERENCES_WEIGHT --preferences_weight_match
-PREFERENCES_WEIGHT_MATCH
+pipenv run python gatorgrouper_cli.py --file filepath --method graph
+--num-group NUMBER --preferences filepath --preferences_weight PREFERENCES_WEIGHT
+--preferences_weight_match PREFERENCES_WEIGHT_MATCH
 ```
 
 To add objective measures use the flag `--objective_measures`
 
 ```shell
-pipenv run python gatorgrouper_cli.py --file filepath --method graph --num-group NUMBER
---objective_measures LIST --objective_weights LIST
+pipenv run python gatorgrouper_cli.py --file filepath --method graph
+--num-group NUMBER --objective_measures LIST --objective_weights LIST
 ```
 
 To add objective weights use the flag `--objective_weights`
 
 ```shell
-pipenv run python gatorgrouper_cli.py --file filepath --method graph --num-group NUMBER
---objective_measures LIST --objective_weights LIST
+pipenv run python gatorgrouper_cli.py --file filepath --method graph
+--num-group NUMBER --objective_measures LIST --objective_weights LIST
 ```
 
 A command line of all agruments would be:
 
 ```shell
-pipenv run python gatorgrouper_cli.py --file filepath --method graph --num-group NUMBER
---preferences filepath --preferences-weight PREFERENCES_WEIGHT --preferences-weight-match
-PREFERENCES_WEIGHT_MATCH --objective-measures LIST --objective-weights LIST
+pipenv run python gatorgrouper_cli.py --file filepath --method graph
+--num-group NUMBER --preferences filepath --preferences-weight PREFERENCES_WEIGHT
+--preferences-weight-match PREFERENCES_WEIGHT_MATCH --objective-measures LIST
+--objective-weights LIST
