+Demo 07 - Functions
+===============================================
+
+We will allow the LLM to call a function that you have defined in your code. The LLM will decide when and with 
+which parameters to call the function.
+
+# Function calling
+Function calling is a mechanism offered by some LLMs (GPTs, Llama…). It allows the LLM to call a function that 
+you have defined in your application. When the application sends the user message to the LLM, it also sends 
+the list of functions that the LLM can call.
+
+Then the LLM can decide, if it wants, to call one of these functions with the parameters it wants. 
+The application receives the method invocation request and executes the function with the parameters provided by the LLM. 
+The result is sent back to the LLM, which can use it to continue the conversation, and compute the next message.
