+# Add custom patches
+
+You can add custom patch files to this directory. All custom patch filenames must have the `.patch` extension, for example `<patch_name>.patch`.
+After all Magento patches are applied, custom patches are applied in alphabetical order from the root of the Magento project as shown in the following example:
+
+    ```
+    diff -Naur a/vendor/package-name/ClassName.php b/vendor/package-name/ClassName.php
+    --- a/vendor/package-name/ClassName.php
+    +++ b/vendor/package-name/ClassName.php
+    ...
+    ```
+    
+You can use the following command to apply all Magento patches and your custom patches locally.
+``` 
+php ./vendor/bin/ece-patches apply
+```
