 ## Configuring the application
 
 1. The Natural Language Classifier service must be trained before you can successfully use this application. The training data is provided in the file `training/weather_data_train.csv`.  
  If you have `username` and `password` credentials, train a classifier by using the following command:
 
-  ```none
-  curl -i -u "<username>":"<password>" \
+  ```sh
+  curl -i -u "apikey":"<apikey>" \
   -F training_data=@training/weather_data_train.csv \
   -F training_metadata="{\"language\":\"en\",\"name\":\"TutorialClassifier\"}" \
   "<url>/v1/classifiers"
   ```
-  Make sure to replace `<username>`, `<password>` and `<url>`.  
-  If you have `apikey` credentials, use the word "apikey" as your username and your `apikey` as the password.  
+  Make sure to replace `<apikey>` and `<url>`.  
   After running the command, copy the value for `classifier_id`.
