+### Translation rules
+
+Since there can be different additional instructions for each page, there is the concept of a "translation rule" 
+that defines additional instructions with conditions when these are to be used. Such a rule has:
+
+- an optional path pattern that has to match the path of the page
+- an optional content pattern that has to appear in the content of the page
+- the additional instructions to be added when both patterns match or no pattern is given.
+
+A common use case would be to give specific translations for certain words. That'd be done by adding a rule with the 
+translated word / phrase as content pattern and "Translate XXX as YYY" as additional instruction.

 ## Notes about the implementation
 
 - To have a painless startup, the identification of properties that need translation is heuristic. Standard

+OpenAI provides [function calling](https://platform.openai.com/docs/guides/function-calling) so that the AI can trigger
+operations on it's own. There is an interface

+that can be implemented by OSGI services to provide such operations. There are two basic services
