+2. AI text generation smart picker

+
+Chat with AI
+~~~~~~~~~~~~
+
+1. Chat User Instructions for Chat Completions
+
+.. code-block::
+
+   occ config:app:set assistant chat_user_instructions --value="hello world"
+
+The user instructions that are prepended before the chat messages for the AI model to understand the context of the block of text. This is a good place not only to instruct the AI model to be polite and kind but also to for example answer all the queries in a particular language or better yet, follow the user's language. The sky is the limit.
+
+2. Chat User Instructions for Title Generation
+
+.. code-block::
+
+   occ config:app:set assistant chat_user_instructions_title --value="hello title"
+
+This field is appended to the block of chat messages, i.e. attached after the messages. It is done this way to allow it to be used even with text completion models which could have the instructions as "The title for the above conversation could be \"".
+
+3. Last N messages to consider for chat completions
+
+.. code-block::
+
+   occ config:app:set assistant chat_last_n_messages --value=10
+
+The number of latest messages to consider for generating the next message. This does not include the user instructions, which is always considered in addition to this. This value should be adjusted in case you are hitting the token limit in your conversations too often.
+The AI text generation provider should ideally handle the max token limit case.
