 #### Content of a config file
 
+A config file consists of two parts. The first part are some metadata about the device and the second parts are the steps to unlock the bootloader, flash a recovery and install the ROMs.
+
+##### How to write Metadata
+Every config file should have metadata with the following fields:
+- `maintainer`: str; Maintainer and author of the config file.
+- `devicename`: str; Name of the device.
+- `devicecode`: str; The official device code.
+- `twrp-link`: [OPTIONAL] str; name of the corresponding twrp page.
+
+In addition to these metadata, every config can have optional requirements. If these are set, the user is asked to check if they are meet.  
+- `android`: [OPTIONAL] int|str; Android version to install prior to installing a custom ROM.
+- `firmware`: [OPTIONAL] str; specific firmware version to install before installing a custom ROM.
+
+##### How to write steps:
 Every step in the config file corresponds to one view in the application. These steps should contain the following fields:
 - `type`: str; Corresponds to the type of view to generate. There are the following options:
   - `text`: Just display the text given in content.
