+## Running Blend_My_NFTs Headlessly
+
+If you are working with Blender in an environment where you can't use the user interface to change settings within the addon, such as Google Colab, you can instead pass in a config file containing the settings from your local instance.
+
+In order to generate this config file, you can use the `Export BMNFT settings to a file` button.
+![image](https://user-images.githubusercontent.com/16054364/162890685-142ebefe-9ec1-4ff9-9f28-60e800345444.png)
+This file will be saved in the folder indicated by the `Save Path` field.
+
+Once you have this config file, you can run this addon in Blender headlessly by running this command from the directory of your Blender installation:
+
+On Windows
+```
+.\blender.exe --background <path to your .blend file> --python <path to Blend_My_NFTs __init__.py> -- --config-file <path to the generated config.cfg> --operation create-dna
+```
+
+On Linux
+```
+./blender --background <path to your .blend file> --python <Path to Blend_My_NFTs __init__.py> -- --config-file <path to the generated config.cfg> --operation create-dna
+```
+
+There are two mandatory arguments that you need to run this script from the terminal/command line:
+  - Config file location
+    This argument tells Blend_My_NFTs where to find your `config.cfg` file in order to load your desired settings.
+    
+    `--config-file`
+  - Operation
+    This argument tells Blend_My_NFTs which operation you want to perform.
+    
+    `--operation` or `-o` with one of the following three options afterwards:
+    ```
+    create-dna
+    generate-nfts
+    refactor-batches
+    ```
+
+There are also additional optional arguments that you can use:
+  - Change save location
+    This argument takes priority over the save path indicated in `config.cfg`.
+    
+    `--save-path` or `-s`
+
+You can also view this information from your terminal/command line by running:
+
+On Windows
+```
+.\blender.exe --background --python <path to Blend_My_NFTs __init__.py> -- --help
+```
+
+On Linux
+```
+./blender --background --python <Path to Blend_My_NFTs __init__.py> -- --help
+```
+
+It is important that you place the python arguments after the `--` because of how blender parses arguments from the command line. More info about blender command line arguments can be found [here](https://docs.blender.org/manual/en/3.0/advanced/command_line/arguments.html).
