+The rules2yml.py generates a yml file for each OSI proto file containing the rules specified in OSI.
+The yml files are located in the specified rules folder given as an input parameter.
+Additionally, the script generates respective yml schema files to validate the rule yml files in <rules_folder>/schema.
+The schema files contain the message names of the original OSI proto file and a list of applicable rules.
+If a rule has an associated value, e.g. a string or a number, the type of the value is also checked.
 When executing osivalidator, all rule files are validated against their respective schema.
 
+If needed, the rules folder can be copied and modified for specific use cases, e.g. by adding or removing certain rules.
+This way, osivalidation can be used with different sets of rules.
+
 After successfully running the validation the following output is
 generated:
