+```sh
+export AWS_ACCESS_KEY_ID='...'
+export AWS_SECRET_ACCESS_KEY='...'
+export AWS_REGION='ap-northeast-1'
+dyna -e -o Dynafile  # export DynamoDB Table
+vi Dynafile
+dyna -a --dry-run
+dyna -a               # apply `Dyanfile` to DynamoDB

-## Development
+## Help
 
-After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake spec` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.
+```

+    -p, --profile PROFILE_NAME
+        --credentials-path PATH
+    -k, --access-key ACCESS_KEY
+    -s, --secret-key SECRET_KEY
+    -r, --region REGION
+    -a, --apply
+    -f, --file FILE
+    -n, --table_names TABLE_LIST
