 ## Usage
 - Run `docker-compose build`.
 - Run `docker-compose up -d`.
-- Run `docker-compose exec builder bash`.
-- Run `cp /opt/caffe/build/tools/extract_nfeatures .` in container.
 
 You can get the executable file (`extract_nfeatures`) in source folder.
 
-## Run in DeepSentiBank
+## Run DeepSentiBank
+### Test in docker
+
+You can test creating json in this builder project.
+
+After running the following command, `test_image.json` file will be output to source/DeepSentibank folder.
+- Run `docker-compose exec builder sh test.sh`.
+
+### Test in your project
 Download `caffe_sentibank_train_iter_250000` file from [HERE](https://www.dropbox.com/s/lv3p67m21kr3mrg/caffe_sentibank_train_iter_250000?dl=1).
 
 Then, add `extract_nfeatures` and `caffe_sentibank_train_iter_250000` file to your [DeepSentiBank](https://github.com/generalmilk/DeepSentiBank) folder, and run `python sentiBank.py test_image.jpg`. 
 
 You can get output json file: `test_image.json`.
