 This is a part of blek! File that is responsible for serving and uploading files.  
 This module is released under the GPLv3 with additions, copy of which is included in the top level of this repository.
 
+## Required files
+You need to have `.env` and `config/filed.toml` files for it to run. They have templates that end with `.example` that you can copy and edit.
