+### RECTOR PHP
+Inside `magento-condign-standard` project. You can execute rector php as follows:
+```bash
+vendor/bin/rector process Magento2 Magento2Framework PHP_CodeSniffer --dry-run --autoload-file vendor/squizlabs/php_codesniffer/autoload.php
+```
+The rules from rector that are applied are set inside the config file: `rector.php`
+
+The option `--dry-run` allows that the errors are displayed, but the code is not automatically refactored.
+
+To run rector for `magento` projects you need to:
+- Specify the magento path and the autoload file for the magento project: 
+```bash
+vendor/bin/rector process MAGENTO_PATH --dry-run --autoload-file MAGENTO_AUTOLOAD_FILE
+```
+Example:
+```bash
+vendor/bin/rector process magento2ce/app/code/Magento/Cms/Model --dry-run --autoload-file magento2ce/vendor/autoload.php
+```
