 ## Using Yarle via command line
+
 Just open a terminal, specify config options in a config file (options detailed in [Configuration](#Configuration)) and type the following:
 
-```javascript
-npx -p yarle-evernote-to-md@latest yarle --configFile <path_to_your_file e.g. ./config.json>
+```sh
+npx -p yarle-evernote-to-md@latest yarle --configFile ./config.json # path to your config file
 ```
 
+You can also override properties in the configuration file with command-line arguments. Note that only properties of types like `string`, `string[]`, and `boolean` can be overridden. 
+
+```sh
+npx -p yarle-evernote-to-md@latest yarle \
+  --configFile ./config.json \
+  --enexSources ./test.enex \
+  --outputDir out-new
+```
