-End users don't have to copy _syside-cli.js_ near the _syson-application_ jar anymore.
-_org.eclipse.syson.syside.path_ application option is not useful and has been removed.
+By default, end users don't have to copy _syside-cli.js_ near the _syson-application_ jar anymore.
+The embedded _syside-cli.js_ is copied in a system temp folder and executed from there (with node).
+But, if you encounter execution rights problem, you can still copy _syside-cli.js_ in a place where you have the appropriate rights and use the _org.eclipse.syson.syside.path_ application option.
