 To extend the build process, you can create a `additional_packaging.py` file in the same file level where you have your globalConfig file.
 
-This file should have the `additional_packaging` function, which accepts add-on name as its only argument.
+This file should at least have:
+
+- the `cleanup_output_files` function, which accepts `output_path` (str), `add-on name` (str) as its arguments.
+- the `additional_packaging` function, which accepts `add-on name` (str) as its only argument.
+
+First the `cleanup_output_files` function would be called from `ucc-gen` build process and then `additional_packaging` function.
 
 See the following example for proper usage:
 
-* Build custom UI after `ucc-gen` finishes all its necessary steps.
-* Use a workaround for a `ucc-gen` feature that has not been implemented.

 # `.uccignore` file
 
+!!! warning "Deprecation Notice"
+    This feature has been deprecated from UCC framework as of v5.53.0 as the feature is ambiguous. You can achieve the same functionality using [additional_packaging.py](./additional_packaging.md). The `cleanup_output_files` provides a feature to clean up files after the source code has been copied.
+
 This feature can be used to remove files from the output **after** the UCC template files were copied and **before** the source of the
 add-on recursively overrides the output folder.
