+# Custom configuration file
+
+Due to the nature of how plugin updates work, your `renamerOnUpdate_config.py` file will get replaced with the fresh copy resetting it to default values. To work around that you can create a custom config file and use it instead.
+
+- Create a copy of `renamerOnUpdate_config.py`
+- Rename your copy to `config.py`
+- Use the `config.py`(it will default to `renamerOnUpdate_config.py` if not found)
+
+> **Note**: Since `config.py` file is not tracked it won't get updated with new configuration options, so you will need to update it manually.

 ## Template
 To modify your path/filename, you can use **variables**. These are elements that will change based on your **metadata**.
 
  - Variables are represented with a word preceded with a `$` symbol. (E.g. `$date`)
  - If the metadata exists, this term will be replaced by it:
 	 - Scene date = 2006-01-02, `$date` = 2006-01-02
- - You can find the list of available variables in `config.py`
+ - You can find the list of available variables in `renamerOnUpdate_config.py`

 In the example below, we will use:
 - Path: `C:\Temp\QmlnQnVja0J1bm55.mp4`
