+**Note:**
+
+For excluding files and path we use [ignore](https://www.npmjs.com/package/ignore) package.
+
+_`ignore` is a manager, filter and parser which implemented in pure JavaScript according to the .gitignore spec 2.22.1.
+
+**All paths provided must be relative to the source path**
+
+Examples
+--------
+
+#### Convert LESS files inside a folder excluding `node_modules` and `vendor` subfolders.
+
+```bash
+$ less2scss -s ./less_folder  -d ./scss_folder -r -e 'node_modules,vendor'
+```
+
+#### Convert LESS files inside a folder excluding all subfolders whose name begins with `test`.
+
+```bash
+$ less2scss -s ./less_folder  -d ./scss_folder -r -e 'node_modules,vendor'
+```
