+## File System Layout
+Inside the data folder, create sub-folders per device. Inside each of the device folders, store the raw files that contain the sub-ghz data, etc.
+
+The device order list, and button list, is based on the sorted file order. This is enforced by the following naming convention:
+
+```
+/data_folder
+  - 00_Device_1
+  - 01_Device_2
+     - 00_Button_1.sub
+     - 01_Button_2.sub
+```
+
+The first two digits and underscore will be stripped before display. Additionally, underscores in folder and filenames will be replaced with spaces.
